my 2 cents worth. First, just so you know, I'm VERY cheap when it comes to bow hunting. I do not believe in spending money on things like range finders, $300.00 ground blinds, scent-lok suits, $1000.00 bow set ups, etc. I don't understand how you plan on using your range finder during bow. Once the deer starts heading your way are you going to contiusly check his distance...30, 25, 20,19,18,17,16. Then put the range finder down and draw your bow. To me that's a set up to fail. Now if you are hunting with a rifle and you see a buck at about 200 yards...then I can see using one.

Good luck!
