Nikon Scope .... I have a Nikon Rangefinder too, but there may be something better for the money.... I haven't found it, but there might be ...... but the scopes are a lock.
I read a little bit and someone mentioned that Bushnell is discontinuing the 4200? Sometimes the things you read aren't true, but I wonder if there is a reason (if true).
I second HEAD0001. Spend $600 on something like a Zeiss Conquest and forget the range finder for anther day. If you are shooting something like a 243. Win., 270 Win., 280 Rem., 308 Win., 30.06 Spr., 7mm/08, 7 mm Rem Mag. etc. .... you sight in dead on at 150 yards and you are more or less good to go from right on you out to 250 yards with little or no vertical "hold" adjustments necessary for deer sized kill zones.
Bushnell came out with the 6500 Elites this year but the 4200's are still available. The 6500's are more costly. For that price I'd get a Zeiss Conquest.
