I have a pair of (now discontinued) Leupold 10x42's and don't see anywhere to screw in an adapter; am I missing it or does it require something else to mount to a tripod?
I don't know if you can use a screw in adapter on those but Leupold makes a velcro stretch strap mount for 20 bucks. It worked very well on their 15's I tried recently.
Let me know if you want a strap down type one to try out and I'll send one up to you. I've got the one Leica makes and it just sits, I'd rather send it to someone to use it.
