My old Zeiss Victory 8X45 RF binoculars crapped out after 15 years. I would like opinions of the above listed range finders. The Revic BR4 and the Leica 3500 CRF are priced similarly. I have a Kestrel Elite so I am familiar with compatibility of the Terrapin X and the Leica. I like the Revic's 10X vs the 7X of the Leica and Terrapin X. Interested on you opinion of reliability, warranty, range, etc.
