SIG SAUER Sierra3 BDX 3.5-10x42mm Rifle Scope 30mm Tube, Second Focal Plane SOSBDX33111
Tons of awesome tech packed in this scope but as someone who typically has horrible luck with new tech and gadgets, this worked like a dream. Super easy to set up the ballistic calc and the rest was like shooting with a spotter. Well worth the investment. Also love the illuminated R1 reticle

I am very old school when it comes to sites but decided to take a leap on digital scope. Setting up the zero was typical like any rifle scope, but with the assistance of the application and selecting ammunition type made changing of ammo even easier. I also like the fact if you don't have your phone it will automatically preset to last loadout on rifle. I set multiple ranges on the app and went back to try everyone out and I hit steal every time. I'm still skeptical about digital scopes but this seems to be changing my mind.
Pros:
easy set up
user frendly
application amazing
Cons:
uses batteries
Would recommend: Yes
