Sig Sauer Kilo3K BDX Rangefinder

Sig Sauer Kilo3K 6x22mm with BDX 2.0

I bought this brand new two weeks ago. It works perfectly but I had 3 RF’s and am only keeping one. 
This one has Ballistic Data Xchange 2.0 (applied ballistics). There are 8 predetermined ballistic groups on the rangefinder that can be used, or you can use the Sig BDX App on a smartphone to build up to 25 custom bullet profiles. 
It has onboard temperature, pressure and humidity sensors for ballistic calculations. 
$580 shipped to you.
