Looks like a winner for crossbow guys - SIG SAUER Whiskey5 10x42mm Rifle Scope 30mm Tube, Second Focal Plane

I was a little hesitant at first but thought I'd give this a try. I have a Ravin crossbow with over 400 fps. I did upgrade all firmware (and made sure all units had full power since after reading these reviews I do not want to power down anything while updating) Gotta go into some sub menu in App but I entered FPS and Bolt weight. Set up the targets on my 5 acres and WOW. Very impressed with the hold overs. All of this took a little time and techy know how which is why I'm giving it a 4 star instead of 5.
