I learned rangefinders are not covered!! I sent one back 3 or 4 years ago when the display went south. I got an e mail back saying the rangefinder was not covered under their warranty, but that they would ship a new model (upgrade) that was significantly better than the one I sent to them for repair at a very favorable cost. I replied back that that was acceptable as the new models had features that I liked. when I received the replacement, the bill attached was as much or more than what I could purchase the new model for at multiple retail stores here in Reno. I have probably 15 of their scopes on my rifles and slowly swapping out older models for newer ones when I can get favorable prices on the internet. I have had minor issues with many regarding tracking issues, but once sighted in, they have held zero perfectly on hunts. But, I have found the 30 MM tubes to be helpful for my 70+ year old eyes.
