Battery pack was easy to install and last all night for hunting

Great quality great price great customer service super fast shipping will definitely buy from again

This thing is the bomb and the way it works with my scopes makes it great. I thought about buying the individual rangefinders that mounted on the gun but this one works with any of my ATN scopes and i just had to buy one.

have not yet mounted it, directions to download firmware is a little complex for an old man , seems a bit heavy

This range finder will add to the already, ability of the scope I purchased. I am well pleased. My hardest decision will be what rifle I will mount it on.
