I will say technology does matter to a certain point. For example, using game cameras, scent protection, calling devices, stands etc..can greatly improve your success rates.
However, having the latest greatest bow may be over hype. I am starting to believe you can kill a deer with a $400 bow just about as easily as a $1000 bow. That is not to knock those who wish to spend the money, they probably have a better bow. The question is though, how much better? Idid shoot my dad's 15 year old bow and there is a HUGE difference in today's technology and would be worth the upgrade.I'm going to buy a used bow from a friend and take the savings to buy more game cameras, a stand and a gps!!!
