If you are shooting to compete and not just practice for hunting, and the guy next to you is using binoculars...you will lose.
It is a competition whether you guys like it or not. If you choose not to compete and just practice for hunting, that is your option. But don't be aggravated by someone who chooses to shoot to win!
Sometimes I compete, sometimes I practice for hunting.
If I use binos, I love Nikon Monarch's. It's what I hunt locally with. They are not too big and bulky, and give a very clear view. They don't get in the way of my draw. (Without breaking the wallet too bad).
