I think xbows are responsible for the vast majority of the increase. OnX, Gaia and other mapping software is just a digital copy of what we did for years on topo maps. Mark them up, look for terrain features, overlay with aerial photos... I have killed plenty of deer prior to having Gaia, just by picking terrain features on a map and going in. 1st or 2nd hunt... As far as learning, social media like Youtube, FB, etc videos, are the last place I would look to learn abouy bowhunting.
The jump from compound to xbow is less than stick to compound....
Remember the last time you nestled the stock of your compound against your shoulder. Fingers wrapped around the pistol grip. Forestock securely clamped in a tripod. Peer thru the 4x scope with lighted reticle and range preset from built in range finder. Flip the safety off. Send a razor tipped arrow towards a deer. 80 yards away.
Ya, me neither.
