Awesome combination!!!!! - SIG SAUER BDX Combo Kit 6.5-20X52mm Rifle Scope w/KILO1600BDX Laser Rangefinder

Not sure what other reviewer is talking about. Glass on mine is clear and bright. Can't tell much difference between this Sig BDX scope or my Vortex viper HS/Leupold VX3i for clarity.
Reticle is a little thick, so not really a precision type of sight, but that's not it's purpose.
As far as I know, you'll need a smart phone to bond the scope with range finder, no other way to do so to my knowledge. Once bonded, no phone necessary. However, you want the phone/app combo to store your custom loads, which will then optimize the accuracy for a given load, with the scope at any distance ranged from the range finder.
Range finder is excellent, fast. Transmit data to scope quickly. Scope will be ready before you are.

Very pleased, definitely recommend.
