I have the 320 second gen with decoy. First day I took it out I called in 6, got 2 missed 1. 3 of those dogs came right on top of me in a pack at 35yrds, I could only get a bead on one. The decoy took the focus away from my position.
It worked pretty good I would say, first e-caller I have ever used. Remote has crazy range too, saw a video they tested it to 300 yards. It will work without line of sight too.
