Nikon Trailblazers. Compact and Inexpensive. I carry them all the time, in my fishing pack and pop them out constantly. Mainly, using them for looking at risers, trying to figure out what stage, of what bug, is on the menu, on my two, local, Spring Creeks. I cant say enough good things about them for the price, about $100.00. Excellent for camp and for birding also. If I still Archery hunted, I'd carry them for that also.
Next up in price is the Vortex Diamondback model. My adult son uses them extensively hunting and shed hunting. He beats the shit out of them dropping them on rocks, dropping them in creeks and they never have faltered. Last weekend, at the Coast, he dropped them in the shorebreak. They got carried about 100 yards down the beach, until I found them after a wave receded. They were submerged for about 45 seconds, in salt water. We rinsed them off in fresh water and dried them out. Next day, they were good as new. I was very, very impressed.
Here's the kicker, he has and uses a bino harness. He just forgets to clip them in at times.
Have fun.
