Advancements in technology will never replace ones ability to effectively shoot a bow without practice,preparation,scent control etc, and most of all luck. I have bowhunted with a recurve bow for over thirty five years with a modicum of success. If technological advances in bowhunting offers a hunter a better chance at killing a deer I have no problem with it. Good luck if you you can spend a buck to increase your odds. Its hunting and technological improvements in hunting implements are a natural progression.
