To do that, you have to collect weather data, lunar data and solar data for the times you are seeing animals and the times you aren’t. Obsessive Hunting Disorder  does this for you.

You enter the location, time of day and the animal activity and all of the other data is automatically calculated for you. Create reports to pull the information that has been entered by you and many other hunters.

This is how you really pattern an animal!

You cant do it without Obsessive Hunting Disorder

Bowmaddness–                Hi Levi, Have you archery hunted in PA this year if so have you had any luck?

Levi Morgan– I hunted in Greene county PA this past season with no luck…hunted public ground and it was tough…I killed a good one there a couple years ago though

Double S- Thank you Levi for all the things you do for the great sport of archery. That’s all. pass

Levi Morgan – Man I appreciate that….It’s been good to me

Ghost23– Levi, what is your greatest accomplishment in archery?

Levi Morgan– My greatest accomplishment in archery ……wow….that’s a good ???……It would have to be winning Louisville!

Ohio Mossy Oak– … Ohio Deer harvest numbers and deer/vehicle accidents have been on the decline for multiple years and many hunters are saying they are not seeing the deer they used to, and that herd numbers may be down overall .Not buck numbers, but in general……. I know you hunt and manage land in Ohio. Have you noticed anything of this sort? And how do you feel about increased cost for both Resident an non-resident deer hunters equally, and decreased antlerless bag limits?

Levi Morgan– I definitely feel that deer numbers overall are down in Ohio…but not buck numbers…I think it is due to the liberal rules on doe harvest jumping in the last couple years….I wish the tags wouldn’t go up as well….

PAbowhunter86– Levi, how many shoots do you attend each year?

Levi Morgan– around 15 or 16….its alot but I love competing ….all those are in a 6 month period

SierraMtns– Hey Levi, Any pointers for someone wanting to compete. I have done a couple 3D shoots. There seems like some many different types of competition. How did you get started?

Levi Morgan– I agree and think that there are way too many venues in this sport…..but I would say pick the one that you feel more confident in and the one that you can best practice for!

Levi Morgan– My dad was a huge hunter….and he introduced it to me….

SierraMtns– Cool…thanks

XFBrian– Do swackers really work like they say or is it just tv???

fasst– lol

Levi Morgan– Man if there is one product that I truly believe in…it is swacker I have no issues at all with them…from the design to toughness they are no doubt my favorite bhead….just stay away from the shoulder bone….the only deer I have lost was from a shoulder shot…but if u hit a deer just right in the shoulder with any bhead u r screwed….no need to hit that far forward with that big of a cut

XFBrian                – lmao thanks for your time

XFBrian                – and CONGRATS on the baby

YoungTNArcher– What is the longest shot you have taken at a target? What is your longest shot while hunting?

Levi Morgan–  200 at a target…….I don’t know if I should answer this but oh well…..120 on a mule deer!

Levi Morgan–  thanx xfbrian

YoungTNArcher– Did you hit the mule deer?

Levi Morgan–  Smoked it….but very controlled situation

buckeyeguy2299– BESIDES NAME THAT GAME:)…WHAT IS YOUR FAV HUNTING SHOW ON TV? AND WHAT ABOUT IT DO YOU LIKE?

Levi Morgan – Its Name The Game Jason…lol…and I would say the Drurys stuff…they are awesome hunters and I’ve been watching them since as long as I can remember…I’ve learned alot from them

buckeyeguy2299–  GREAT …….HAVE A GOOD NIGHT BUDDY AND TTYL

ferretboy–  First off, pleasure meeting you again and now my question: Many purists dont consider 3d real archery, we all know that you’re one of the best in the world at that game, how did it feel shutting down the naysayers by having such a huge indoor win and how proud were you to put that one into your vast and growing list of accomplishments? And congratulations on both the Championship and the new baby.

Levi Morgan–  3d is the toughest venue of archery….thats why so many great shooters dont shhow up….u actually have to think and plan…and manage…..and shoot…and judge….Indoors was awesome for me because I never practice that stuff and because people said the only reason I won was because of my yardage….you cant win a 3d on yardage alone

youngbuck98–  oh ok

Levi Morgan–  Indoors are tough because they are so easy everyone can compete…

Levi Morgan-  if that makes sense…lol

youngbuck98–  levi what method do you use to judge yardage?? do you look at the target or go bye the ground

Levi Morgan–  I use a little of both young buck….but mostly target

ferretboy–  total sense, i shoot both and perform better in 3d, for some reason i feel less stress, thank you for the answer

geezer047–  Hey, gonna be hot this weekend if you and Sam need a cold drink of water stop by Koty’s truck. Charlie

Levi Morgan–  Haha…no problem man…I may make Sam stay home in this heat…not good for being 7 months along

hrtlnd164–  Levi, which would you rather have. A 180" buck or another World Championship…(and you can’t say both).

Levi Morgan–  Definitely a 180” buck…easiest one yet…haha

Levi Morgan–  heck a 160

hrtlnd164–  I’m with ya there

ironarcher–  Oh I’m not sure.. ok I guess I didn’t really understand the answer about judging yardage..

ironarcher–  or maybe I missed it haha

Levi Morgan–  I look at the target and study it for detail while taking alot of other things like lighting, terrain, etc. into consideration…if I’m still not confident I will check it with the ground to see if I get something different

ironarcher–  got ya thanks Levi

jrm81–  Who are some the guys that you just flat out enjoy shooting with in 3D and indoors? Also in your opinion, who are some of the up and coming archers that we should keep our eye on?

Levi Morgan–  Guys Like Darrin Christenberry, Nathan Brookes, Danny Mcarthy, Ken Lance, Chance B, and so many I cant name em all…….and a couple up and comers are Garrett Ayresman from WV that kid is awesome…..and Ty Adkins to name a couple….and Jeremy Elliot

masonbanta–  Did you just decide one day to start shooting the Pro stake or did you work your way up to it over the years?

Levi Morgan–  I’ve shot since I was 6 years old and worked my way to a win in the mens open class in the ASA when i was 13…I quit for a couple years and when I came back I was hungry to be the best of the best so I jumped right in

masonbanta–  Thanks Levi and good luck this weekend.

Levi Morgan–  thank u

rdraper_3–  Can’t really think of any questions right now. I’d just like to say congrats to you and Samantha and good luck in Marengo, OH

Levi Morgan–  thanks so much…really appreciate that

scott*devin–  ohh sorry, Levi do you like the Mathews monster series bows?

Levi Morgan–  Yea I do man…I have had my ups a downs with them by my ups have been amazing…..I love them especially for hunting….but I’ve also won 3 Worlds with a monster 7

sugice–  levi, first it is a pleasure to meet you and I really enjoy your show, now what was your most exciting hunt and which state has presented the most challenging hunt of your career and why?

Levi Morgan–  most exciting was the double double droptine from my dads farm in Ohio…no doubt that’s the most exciting hunt of my life…..most challenging is spot and stalk muleys in the Missouri river breaks of Montana….but that’s also one of my fav hunts….

sugice–  thank you, good luck this weekend and congrats to you and Samantha. If you ever get up to Maine look me up, I've got some great hunting land available.

Leviticus–  Awesome…..MOOSE????

sugice–  absolutely!

sugice–  bear and some big bucks

sugice–  got my permit for a bull this October

Levi Morgan–  awesome

20ftup–  you bought it

tarheelmr7–  what target/lighting/terrain scenarios trick you the most? Can you pick one scenario and give a tip on how not to get my butt kicked by the yardage?

Levi Morgan–  Tarheel—-The one that gets me the most is if the lighting isn’t consistent…if its dark the targets look farther and if its bright the targets look closer…..so if it has been overcast all day and I’m calibrated for that, then all of the sudden the sun comes out and the target is bright…if I’m not careful I will shoot him in the knee…lol

Levi Morgan–  …see ya’

fasst–  lol

tarheelmr7–  thanks man. I’m gonna pm you. Hope to see you this weekend

Levi Morgan–  no problem

youngbuck98–  do you think a c4 is a good bow for target shooting or should I go with the apex 8, either one what would be the length on the front and back bar and how many weights to balance it out good, i shoot b-stinger premiere xl bars

Levi Morgan–  29″ draw and under I would go with c4…over that I would go apex 8….both good target bows….I would start with a 30″ front bar with about 4oz and a 12″ back bar with about 13-15oz

fasst–  I am going to run thru the names that haven’t had a chance to ask a question yet, before we double up. Levi only has a few more minutes slated for the chat!

youngbuck98–  ok thanks man,

Levi Morgan–  no problem

3Dblackncamo–  hey levi, what are your goals in 3D archery right now and how do I get you to Big Pine for some local 3D! good luck in metropolis

Levi Morgan–  I want to win shooter of the year for 3 more years in ASA and help make the organizations better…I’m gonna try to make it out at some point i enjoy shooting out there

AdvanTimberLou–  Levi, congrats on winning Louisville, I was there and see what I thought was the word “manimal” on your shooter belt, what is the meaning behind that?

AdvanTimberLou–  It could have been my bad eyes too, you guys shooting inside outs all day was cool to watch! 🙂

Levi Morgan–  Thats a nick name that Greg Poole gave me…he had that quiver made for me….he says im not all human and that I have to be at least half animal…lol…so he calls me the manimal

fasst–  lol

Fortyneck–  Hey Levi, thanks for your time, In your opinion what peep/sight housing/pin size combo is best suited for hunting at longer distances? Also do you have a favorite older model bowhunting bow that stands out with exceptional accuracy and/or shootability for those that can’t afford the absolute latest equipment.

AdvanTimberLou–  After seeing you shoot, you’re not human! Congrats again and congrats on the future addition!

JHENS87–  sounds like poole

Levi Morgan–  I would go with a 1/8 peep and either a .10 or .19 for pin size but if u can see smaller then I would say go for it….and for an older bow I loved the switch backs

GoosebyFLuFLu–  How long do you plan on shooting professionally? Also do you plan on shooting until you no longer are able to or until is no longer is fun? Thanks for taking the time to answer everyone’s questions.

Levi Morgan–  thanks lou

Fortyneck–  Thanks, BTW Manimal…great show

Levi Morgan–  I’m not real sure…I’ve got a little boy on the way and I can already tell that archery is taking a back seat…as it should….I am going to pray about it as time goes on and we will see what the Lord has in store…good question

GoosebyFLuFLu–  Thanks!

fasst–  good answer!

Levi Morgan–  thanks fortyneck

JHENS87–  Whats your hunting setup for whitetails this year? Any sidebar, lens, longer front stab normally seen in target shooting?

Levi Morgan–  I will be running same as usual for me…mr7 with a 15″ front bar and a 10″ back bar…..7 pin CBE tek hunter but no lense….also gonna use the Helium some I like that bow….especially in blinds

JHENS87–  nice, thanks

Levi Morgan–  no problem

NY911–  Levi – not so much a question, but a comment – thanks for taking a stance with the shenanigans at recent tournaments it really shows how you (and the other Pros who spoke up) care for the future of the sport. Your voice alone equals 100 of ours. Keep tearing it up and good luck on the future addition!

Levi Morgan–  Thanks…I want to do all I can to help these orgs out with rules and decisions…there is a small group of us pros that are starting to work together to get things changed for the better..

Wazz13– Outside of your Pro Hunter’s, what would be your go to arrow for hunting? What would be you goto arrow for 3D?

Levi Morgan–  I would go with a velocity 300 for hunting and TRiple xxxs for 3d

Wazz13                –   Thanks Levi, best of luck and God bless.

archerdad–  nothing just here to observe… congratulations on your good fortune levi the baby and the winnings

Levi Morgan–  thanks guys

hitman846–  In your travels, have you ever had a fan or someone you don’t know tell you “Dude, you should hunt with me for a few days at my place” and took them up on it?

Levi Morgan–  yes and no…not really that spur of the moment but I have had people email me with an idea for a hunt and within the month i was there…not to say I wouldn’t if the circumstance was right….haha

hoytbullrider–  Whats your best advice for a younger shooter , like myself, to get into 3d and indoor when only having a hunting rig (mathews monster) competition against the guys with bows setup just for 3D/indoor , sorry if its a wild question

Levi Morgan–  that’s a good question….I wouldn’t be scared to take my hunting rig to a tournament….that bow doesn’t know its not a tournament bow….while its probably a little more critical and maybe slower and doesn’t have all the bells and whistles it will more than likely still shoot awesome….just think of it this way…if you can beat them with a hunting set up then imagine what u could do with a tourney rig…..

Ohio Mossy Oak–  I wouldn’t mind getting in a follow up if he has time. Or maybe I can just hit him up on facebook?

hoytbullrider–  thanks

Ohio Mossy Oak–  On my last question regarding Ohio deer an tags etc. Did you say you’re in favor of a reasonable increase in cost for Residents an non-resident deer hunters?

Ohio Mossy Oak–  Also..I feel if you own over 50acres even as a non res you should pay less being a property owner…Just wanted to say that

Levi Morgan–  I obviously would rather the price not go up when I think of myself….but if the state is using the money to put back into conservation then a little raise would be ok with me….I agree with u on the landowner thing…I’ve been saying that for years…haha

 Levi Morgan–  not that it matters to them what I think

GoosebyFLuFLu–  Before I leave I wanted to thank you again for taking the time to answer my question and others as well.

Mathews122–  Levi do you have any idea what would be the best 3d tournament bow for a person witha 26 in draw

Levi Morgan–  no problem man. I wish we were all in a room so I could answer in more detail

Levi Morgan–  id say Mathews prestige

Ghost23–  What has been the best archery advice given to you, and how did it affect you as an archer:?

fasst–  OK Folks, let’s all give Levi a big hand for taking the time to host this chat!

JHENS87–  Yep thanks again Levi, been a very good chat

Mathews122–  Thank you

Christopher67–  Thank You

hoytbullrider–  thanks

Double S–  A Big thank you Levi!.

geezer047–  THANKS Levi, see you this weekend. Charlie

PAbowhunter86–  Thank Levi Congrats on becoming a dad no feeling in the world can compare!

20ftup–  Thanks Levi stay cool

fasst–  And Levi, please be sure to tell Greg that I was serious in my last text to him a little while ago!…..lmao

fasst–  levi, can you answer one last question for us please?

Levi Morgan–  Thanks guys I really enjoyed the questions

Levi Morgan–  yes sir

fasst–  go for it Ray

ferretboy–  Thanks a lot Levi Morgan

JHENS87–  Good luck, and try to avoid this 100degree heat your coming into as much as possible haha

rdraper_3–  What would you like to see improve in the IBO? I’d personally like to see the Pro’s shooting on the SAME courses as those in lower classes. I’ve only been in it for 2 years and really like it and plan on going to MBO next year, I’m currently in MBR but the only thing stopping me is the whole adjustable sight thing. I’m deathly afraid I’d forget to adjust it and miss a target.

Ohio Mossy Oak– Thanks alot levi. Getting insight on the deer herd here, from a highly managed ohio land owner like yourself means alot..An re-affirms many takes on the deer herd…Good luck this weekend. And god bless your an yours<

zakseppala– what would be the one tip you would give for someone looking to improve their shooting

rdraper_3-  Thanks for letting me get it in there Travis

Levi Morgan–  O wow ray?…thats a long list…lets see….pros shoot on sight….a legit awards ceremony….a qualification to get ur pro card….a shoot off….20 targets per day….a speed limit….etc etc etc

Levi Morgan–  Thanks guys and good night

rdraper_3–  Thanks Levi

Ohio Mossy Oak–  Speed limit !! YES! I love it

archerdad–  thanks for your time levi

Christopher67–  Thanks Levi

AdvanTimberLou–  Thanks again Levi and all the shooter of the year titles won’t mean a thing when you become the title of dad! Enjoy every moment of it! God Bless you and Samantha!

ferretboy–  Another class act, I have really enjoyed the last two featured chats

 

Wanted to give everyone a heads up on the Sure Loc Icon. I recently purchased the Icon 550 with 9 inch extension from a web store. I was very excited to try this new site with the Zero Gravity technology. My enthusiasm was quickly met with disappointment. I put the site together and noticed the vertical frame did not seem square to the mount. The vertical form almost looked bent out from the bottom. My next issue was with how hard the site elevation adjustment turned to make adjustment to various distances (Although this did losen up after awhile.) The windage adjustment was just as difficult. However worse then that was the ‘Cant and third axis adjustment they were next to impossible to change by trying to use the knob, even with the set screw backed out all the way. The only way to make the adjustment was by Allen wrench but if this was by design why have the knobs? Here’s the last complaint and this is a killer. When the site was together there was actualy some play between the vertical form and extension bar. Not good for any site let alone a micro adjust target site. So I called Sure Loc the only thing I can say is there customer service was worse then the site. I was greeted by an automated answering system that told me if I was calling between business hours (8:00 am to 5:00 pm) they were experiencing high call volumes. Which I guess occur all the time because no human did ever answer the phone between those hours. I called several times and left a voice message as instructed. They never returned my call so I shipped the site back to the dealer and purchased an Axcel. I bought my first Sure Loc about 18 year ago and loved it but that was back when Steve Gibbs was still running the company God rest his soul he must be turning in his grave.

“Sport specific training” is a big buzz word for any activity. Bow Hunters scour the internet and youtube for “hunting specific” exercises that will increase their ability to harvest deer come fall.  As a fitness professional and international presenter I deal with lots of questions from clients and other trainers regarding how to develop sport specific programs but is “sport specific” really the way to go? Does sport specific training even exist in the fitness world? 

 

 

 

 

 

 

 

 

 

 

With the modern day ritual of “hunting camp” hunting does not always get associated with health and wellness. Perhaps it is because at camp there are usually more calories consumed in liquid form then sold, many items in the cupboard would survive a nuclear apocalypse and a pound of butter is the standard unit of measurement for most recipes. Hunting camp aside there is an amazing benefit modern hunting offers the hunter and his/her family when it comes to their wellbeing. I am referring to seeing your meat in the field before you see it on your plate.

 

I grew up in a suburb of Detroit and spent my whole life in metropolitan areas until I was almost 23 years old. If you were to ask me, “were does your beef come from” I would answer you “Meijer” and then look at you like you had a third eye growing out of your head. What I was really saying was I have no idea, where my meat comes from, what’s in it, what it as eaten, how it was raised and how long it has been since it met its demise. These are important things to know! We eat what our food eats, what is put into its body we put into ours. That can be a laundry list of things I would never consciously consume but do every day because I don’t know it’s there.

 

Laporte Archery would like to introduce you to a new archery sport; the Bow-Trap!

We are organizing an introductory tour in the states of Virginia,West Virginia, Kentucky, Tennessee, North & South Carolina from June to August with a possible extension to September.

I am a math teacher in a small high school in Alaska and we began exploring a concept this year for an idea I had a while back.  The general thought is – if you make a laser site and have it mounted above the arrow can you align it to approximate the trajectory of the arrow?  If you can, how far would it approximate that trajectory?  We took that idea a step further and said, if we add a second laser to start approximating the trajectory where the first one leaves off we can really extend the range of the site.  In fact multiple lasers could be used to approximate the trajectory as far out as desired.  Multiple lasers would project multiple dots on the target but the lowest dot would always be the one to use.

We did in fact develop the theory behind this and built a working prototype.  It works.  The students won best of show at the local school wide district science fair.

It only took two lasers to approximate the trajectory on a Bowtech Allegiance out to 50 yards with a maximum 2″ of error.  The following video is of us testing the site shortly after we set it up.  The first clip show 5 shots at random distances out to 50 yards and the second clip shows popping balloons at 10, 20, 30, 40, and 50 yards on a bright sunny day.

If you are interested in the theory behind the development we established the following procedure:

This procedure includes a fair bit of math – that was of particular interest to me as a teacher using this as a learning project – but this can be automated with the computer and the initial setup of this site is actually quite simple, fast and effective.

Procedure

Since the flight of an arrow follows a decaying parabola, its trajectory can be approximated with a quadratic equation in the form of y=ax²+bx+c where y=drop and x=distance from the target.

1. Record arrow drop from three distances covering the effective range of the bow by shooting groups of arrows from each distance and recording average arrow drop from aim point.
2. Create three different equations using the known x and y values, with x=distance from target and y=arrow drop from aim point.

Y₁=ax₁²+bx₁+c

Y₂= ax₂²+bx₂+c

Y₃= ax₃²+bx₃+c

1. Solve for the unknowns: a, b and c.  Do this by using a graphing calculator and setting the numbers up into a matrix and transforming the matrix to reduced row echelon form.
2. Once coefficients a, b and c are solved for they can be plugged into the quadratic equation ax²+bx+c.  This will create the quadratic equation that predicts the arrow trajectory.
3. Use Excel and the quadratic equation to graph the predicted arrow trajectory.
4. Once graphed, use lines of best fit over different ranges to follow the trajectory of the arrow with an acceptable margin of error. Ultimately, these will be the lasers.
5. By using multiple lasers, or lines of best fit, we should be able to approximate arrow trajectory out to the effective range of the bow. Multiple lasers will project multiple dots on the target, but the bottom laser dot will always be the approximating arrow trajectory.
6. Construct a laser mounting apparatus that can be mounted onto a bow and which allows lasers be adjusted in elevation as well as fine tuned left, right, up or down. This laser mount must be rigid enough to maintain its position on the bow while sustaining the shock of repeated shots.
7. Take the first line of best fit and find the equation of the line in slope-intercept form. B, or the y-intercept, will be the distance between the laser and the arrow.  Mount the laser at this distance above the arrow.
8. The line of best fit will cross paths with the arrow trajectory at two places on the parabola.  Solve for the x values, or distances, where this occurs by setting the equation for the line of best fit and the quadratic arrow trajectory equation equal to each other and solve for x.
9. Site the first laser in at the previously solved for x values by shooting a group of arrows at the two distances and adjusting the laser accordingly. After this step your bow should be striking your aiming point at the two distances.
10. The next laser can be aligned without shooting the bow at all.  The two lasers will cross at a specific distance. This distance can be solved for by setting the equations of the lines of best fit equal to each other and solving for x.  Simply adjust the top laser so it is on top of the previous laser. Ultimately, at these two distances you will see only one dot.
11. Repeat the previous step to align any additional lasers.

Now you can test-shoot the bow from essentially any distance that your bow is effective to and see if the lasers allow you to shoot within the predicted margin of error at these distances.

The following is the actual implementation of the procedure on the test bow (Bowtech Allegiance) with the real numbers and generated formulas.

Step 1: Record Arrow Drop.

 

	Distance from Target	Arrow Drop (Inches)
Group 1	15 Feet or 5 Yards	0.4375 Inches
Group 2	60 Feet or 10 Yards	-5.3125 Inches
Group 3	150 Feet or 15 Yards	-46.8125 Inches

 

Step 2: Create Equations.

 

0.4375=a(32400)+b(180)+c

-5.3125=a(518400)+b(720)+c

-46.8125=a(32400000+b(1800)+c

 

Step 3: Using spreadsheet program utilizing rref solve for a, b and c.

 

a= -0.0000171467764060

b= 0.00478395061728

c= 0.1319444444444440

 

Step 4: The quadratic equation predicting arrow trajectory is:

 

-0.0000171467764060x²+0.00478395061728x+0.1319444444444440

 

Step 5: Use Excel to make a graph of projected arrow trajectory using the previously found quadratic formula.

Step 6: By graphing trajectory over shorter distance ranges and using line of best fit on Excel, we were able to come up with a combination of two lines of best fit that approximates the projected arrow trajectory from zero out to 50 yards with an error of + or – 2 inches.

First Line of Best Fit:

 Second Line of Best Fit:

 Step 7: We were able to use 2 lasers and have a margin of error of 2 inches and were able to approximate an arrow strike point out to 50 yards. The top laser mount location is 25 inches above the arrow.  With a top laser mount of 33 inches we, we were able to approximate arrow strike point out to 60 yards.

 

Step 8: We chose 1 inch extruded aluminum display rail since it was readily available, rigid, lightweight and laser fixtures could be mounted anywhere along its length. This was mounted to the bow utilizing the bow’s standard site mounting holes.

 

We modified a generic green laser pointer to use as our laser sites. To allow for windage and elevation adjustment of lasers we mounted one end of the laser on a horizontal threaded bolt and the other end of the laser on a vertical threaded bolt in an aluminum square tube.

 

For our power source we made a battery pack using standard plumbing supplies and screwing it into the stabilizer-mounting hole on the bow. The bow was used as the ground and we routed one positive wire through a momentary push-button switch on the bow handle up to each laser.

 

The lasers were mounted onto the bolts by soldering a nut onto a ½ inch copper pex crimp fitting and crimping it onto the laser.

 

Step 9: The equation for the first laser line is y=-0.0137x+4.028.  The laser should be mounted at four inches above the arrow.  Mount second laser at 25 inches above the arrow, the equation for this laser is y=-0.0384x+25.132.

 

y-intercept=4.028=distance laser is mounted above the arrow.

 

y-intercept=25.132=distance laser is mounted above the arrow.

 

Step 10: Find where the first laser crosses at both places on the parabola.  See below.

Step 11: We adjusted the laser fairly close at 8.7 yards and then adjusted it to be right on at the next distance: 21.2 yards.  A quick check showed that the laser was right on at 8.7 yards as well.

 

Step 12: We solved for the distance that the laser crossed.  See Below.

 

We then aligned the lasers as to make one solid dot at 23.7 yards.

 

Step 13: There were no additional lasers.

 

Step 14: We tested the site by shooting arrows at random distances out to 50 yards, and all the arrows were within the predicted margin of error (+ or – 2 inches in elevation). See video. Further testing was done to demonstrate both the accuracy of the site out to 50 yards and the visibility of the green laser on a bright sunny day by shooting balloons at 10, 20, 30, 40 and 50 yards. See video.

 

I would certainly like our students to receive feedback on your thoughts about this concept.  We did file a provisional patent on the idea.  I can be contacted at [email protected]
