I really like the Leica 900 that Doug hooked me up with several years ago when they were a close out. Can’t speak to Leica customer service, as I haven’t needed it. I can routinely range past 700 yards, it is simple and quick with a narrow beam. I haven’t even had to change the battery, but suspect I will soon just for insurance.
I have used some ranging binoculars, and so far, have found them heavier than I want around my neck. When they lighten a bit more I’ll consider them, but for now color me happy with the 900s. And btw, all the fancy extra ballistic stuff in some of these things is just gack. I want a fast and reliable reading, period. Anything else gets in the way.
