My Nikon 440 has a lanyard on it I have always just looped around one of the straps on my harness. It always worked well. That snap thing looks OK. $12.50 seems like a reasonable price too.
I lost my rangefinder in Alaska due to this! It took like an hour to find the darn thing as well. When stalking, you can basically leave NOTHING in your pockets or it won't be there at the end, and I learned that the hard way. Who knows if it'll work but it looks good enough for me. Just ordered one, thanks for the link!
Muddy harness has a place for binos, I keep them in a pouch on my stand, so my rangefinder goes there.
Looks cool. Kinda like the "gear Keeper" on out turn out gear for our lapel mics. I think u just gave me an idea. I'm gonna see how much those run & see what I can do to hook it up. thanks for the idea cfdjay.
