I got that expensive Leica RF. It's a small one that bounces around on your front from it's string if I can remember where I put it today.
As an oldtimer I have a lot of gear. I read there are rangefinders built into binoculars now. If I did not have the Leica 1300 or whatever it is I might try that way.
The one item I like is the 7/ 12 x 32mm Leupold switch power binoculars. Those are so handy for scanning while hunting and then switching to 12X to see: "what is it".
The problem is that they were expensive and may not be made anymore. If I did not have the pair I do I would search the net and buy another pair. They are outstanding.
I also got the Nikon Action Zoom 7/15 x 35mm binoculars. They are inexpensive however they are bulky with a narrow field of view.
