Rok, I’m looking for binoculars that lock in the eyespan adjustment I’m sure there is a term for this, but do not see it when searching for a new set. My friends Luepold gold rings lock which I love. I have had a pair of cheap vortex diamondbacks 10x42s forever that I’m going to upgrade and one of the top features I’m looking for is that locking ability so I don’t have to constantly adjust to my eye span. If there is a way to do that on all binoculars and Ive been blind to it or any specific models you recommend that would great. Do not need anything too fancy. Mostly whitetail hunt southeast timber. Out west/adventure hunt once every three years. Thanks
