Re: Best rangefinder at any price & best for the $
The best at any price? I guess Leica Vectors (several models available) around 18000 Euro. Not really fanny pack size and may not go down to 20m.
Best non military kit, what Pete said.
Best non binocular LRF, look at recent post on Bushnell 1500, Swarovski Laser Guide, Leica 1200.
