Enjoy some sky-trolling as you go drone fishing with the SwellPro New TS2 Trollsafe specially designed for Fisherman FD1 Fishing Drone. The Trollsafe mounts directly on your Fisherman FD1 drone and can work in conjunction with the PL1-F or PL2-F payload release. Once you get a bite, the Trollsafe can automatically release the line. This tension is adjustable, so you can accommodate rougher or calmer conditions. The Trollsafe also helps protect your drone by releasing the line in the event of a reel jam or if the line is struck by a bird.
