Thank you very much for the information, Malgus. I have always been a “use the height of the critter as a reference and eyeball the distance” shooter. Only since I started modern archery have I gotten into ranging with electronic devices. We did use an old rangefinder that used lines and a known measurement for double checking distances, but I really learned old school from my dad. I am actually really excited to start learning newer methods. Old school has worked, but new school is definitely the way to go and thus why I am converting.
