I got an email with the following question: “Any tips on estimating distance when shooting 3-D?”
Archery competitions have included unmarked yardage elements for, well, ever. Obviously bowhunters hunted game for thousands of years with no distances to the prey supplied, so being able to figure out how far to shoot is a valuable skill. Modern competitions, though, have included some innovations, such as rules that ban mental schemes for determining distance to a target! WTF?!
The use of such techniques, being mental, was hard to police, so it turned out if you wanted to win, you had to cheat (along with all of your competitors), that is using the techniques while pretending not to! FITA, now World Archery, went so far as to publish the techniques to “level the playing field” while keeping them as being illegal! (See Understanding FITA Field Archery, an extract from the FITA Field Guidelines booklet published by FITA in 1995.)
Hey, World Archery! How about making these techniques legal? After, all they are just mental skills that everyone can learn to do. Then no one would be forced to cheat to win an unmarked shoot!
The first person to publish these techniques and blow the cover of those using them was Kirk Ethridge in his book Professional Archery Technique, which is still in print because we made it so. (I hot linked it if you want a copy.) I will leave it to Kirk to discuss the fine points as he was the first.
