I have been using the bino-harness for about 15-16 years. I have used it in Africa and in the US. I prefer it. I too crawl around on the around on the ground a bit and have never had an issue with binoculars hanging up or digging in. The binoculars are high on my chest and above my arms when I crawl. The elastic straps keep them there. I prefer to shoot from prone when I can, right or left handed which ever is convenient. The binoculars have not got in the way yet.

I like all of us, I am sure, have did the straight over the neck carry and know what a pain in the back side (and neck) that is. It's for me not even an option.

Some years ago I saw someone promoting the over the shoulder carry as MS promotes. I tried it. It is a good way to carry the binoculars if all you do is stand upright and shoot strong side only. If you have to crawl with that carry method, gravity assures those binoculars will be under you. Trying to crawl with a pair of binoculars under your hip bone can be pain. If you have to move fast and or spend all day walking around the bounce is going be uncomfortable.

If you work into a shooting position that requires you to work from the weak side and use the binoculars, you have switch hands with the rifle or move the bino's. To much movement and awkward motions.

MS method of carry for dangerous game with a double rifle makes perfect sense to me close combat, contact imminent.

My favorite shooting activity is gopher hunting. In Montana this is usually done from the front seat of the truck, shooting out and resting the rifle on the open door window. I wear my binocular hardness while driving all day long.
