Best I've used: worth the extra few $$$
October 14, 2015
i've owned an older Callaway and a newer Nikon 40i rangefinder. The Callaway was good, lasted years, until I finally lost it. The Nikon 40i I returned twice due to oil spots appearing in viewfinder. I then purchased the Bushnell Jolt Slope. It is ergonomically better designed (button much easier to use). It is faster acquiring pin than either of the other units. I initially thought the jolt feature would be more of a gimmick, but in all frankness it is pretty cool. And accuracy is fine. It was definitely worth the extra $$$.
Pros:easy to use, fast pin acquisition, bright optics, well made
Cons:none so far
