RE: What is a "serious bowhunter"?
I consider myself a "serious bowhunter" in the sense that I spend more time bowhunting than any of my other passions although I spend a lot of time on them as well.
I do not consider myself a "serious archer" however. I shoot enough to be proficient at targets out to 60 yards so that I can be proficient on animals in the 30 yard or closer range ( a little further when I am elk/mule deer hunting).
I keep my equipment in shape and properly tuned, but I seldom change anything or ever shoot in 3D or any other competition nor do I have any desire to do so.
But while I am not a serious "archer", I have no desire to hunt with anything except a bow, so I guess I am a serious bowhunter.
