I think technology has become the biggest factor in increase in big buck bow kills. First as pointed out bows are better whether that is taking shots from a greater distance or not. They are faster, better, more accurate and sights better etc. Also the technological advancements in trail cameras with the cell phone applications makes it so much easier to get real time info and pattern big bucks. Then ad in the aps for predicting weather fronts and barometric pressure. Also tons of info on internet youtube etc about food plots and creating bedding sanctuaries and patterning big deer. All of these factors involve advances in technology which in my opinion help bow hunting the most due to the length of bow season and especially early season hunting. Oh yeah and HECS suits ok lmao I’m joking on this point but maybe they work I have to say I’m very skeptical on this supposed technological advancement.
