I disagree with whip on this one!
I shoot a lot of 3D and I like to compete. 3D is a game. I do not want to lose points when I made a great shot that hit right where I was looking, but I was looking in the wrong place. The 12-rings on a lot of 3D targets are not in the same place where I would aim on a real live critter! If I miss the mark, I want it to be because I made a bonehead shot, and not because I was looking in the wrong place. I use the binos on nearly every target, and do fast enough that I do not hold anyone up. At all the Traditional Bowhunters of Texas shoots, the rule is that you cannot use binos from the stake, so I look before I even get to the stake, and take no longer than any other shooter.
I use Alpen Shasta Ridge 8x42 binos (about $200 new) for my 3D shoots. I bought my first pair in 2005 and used them with no problems until this past September (these are also my hunting binos. I do not need high end binos fo my hunting as I rarely ever hunt open country where I have to see very far. I was on a mule deer hunt in NM and while getting out of my truck one morning, they fell from the truck seat to the ground. They had been knocked around and dropped several times before this with no ill effects. This time something broke inside the binos and one side would not work any more. When I got home from that hunt I called Alpen and was told they had a lifetime warranty. I sent them in, and in less than two weeks, had a brand new pair in my mailbox. I am sold on the Alpen brand now because of their great customer service.
For carrying them I have a J hook on my quiver belt. I then have a small braided paracord attached to my binos (maybe 5" long) and the binos hang on the hook when I am not using them. It works very well. Up till this year I used a shoulder strap. That worked OK, but got heavy after a while, and was a pain to get off when someone wanted to borrow the binos for a second.
