I wouldn't buy anything if I were you because I think these variants are not as good as they should be. When I started hunting, I wanted to buy a rangefinder, so I used Google in order to find a suitable variant for myself but I didn't manage to do it. I asked my family about this issue, but they said that they didn't know anything. After some days, my friend found out about my problem, and he advised me to use this site: https://www.atncorp.com/range-finder . I purchased laserballistics 1000 from there and everything is okay with it.
