I have owned a Swarovski rangefinder for many years and to tell you the truth I have never needed it once for Minnesota hunting. That is becasue most shots in Minnesota for deer are usually going to be between 50 and 200 yards, which means that if you sight your gun in for being exactly on the mark at about 130 yards you can aim strait on from 50 to 200 yards and not have to worry about anything.

As for scopes, I finally got wise this year. Took off the heavy variable (zeiss conquest) and put on a lightweight old used Buris signature 4x. Should be no problem anywhere in Minnesota, and its nice and light weight to complement the Kimber Montana which is also nice and light in weight. (you spend a lot more time carrying them than shooting them)

Good luck this year.
