Don’t have any experience with the Fury in the field but quite a bit with various Leica rangefinders.
Optically, from what I’ve read and seen the Fury’s are somewhere near the Viper in properties. The Geovid is a high-end Leica Porro Prism Binocular with very crisp optics. So, compared to the Geovid and your SLCs they‘ll be noticeably less crisp for a lot of detailed glassing, which may be a bit frustrating to use for extended periods as a main glass. This would make me consider bringing along another binocular and kind of defeats the overall purpose. Instead of the Fury’s, if wanting a quality ballistic rangefinder and funds are an issue, I’d recommend the Leica CRF 3500. It has ballistic readouts, has one of the most advanced laser systems available, is extremely compact, wears on your belt, and the 7x monocular is Leica quality. Also lets you bring your favorite bino as a main glass.
In addition, all of the ranging systems seem to work OK in ideal conditions. But I’ve been in a number of misty, hazy, rainy or otherwise limited visibility conditions where the Leicas worked and other brands were either compromised or weren’t able to range. Leica has been doing this forever, so their system appears to be superior for ruggedness in all conditions.
Also know there are some CS concerns. All of my recent experiences with Leica over the past few years have been night and day compared to years past. They now have the best warranty of the Big 3 and believe they really mean it.
