Uses your Gopro so the HD quality is great and gets rid of the distorted wide angle. And video through your actual scope is nice. Theres a bit of recoil with the .338 LM used in the video but I imagine on one of my guns that just lay there and smile at me I could use the 240 frame per second setting and watch the bullet fly. One version is through the scope and the other removes the gopro fish bowl look, mounts on any picatinny rail and has 20x power.
