RE: Magnetic vibrators
Yeah we have a couple. I believe the ones we have our called "quiver magnets". We cut flaps on the backs of our floater decoys, almost like the flaps on mojos. The velcroed the magnets to the bottom of the floater. They seem to work good, you just have place the decoy carefully. If you toss it out the impact of the decoy hitting the water will jar the batteries loose.
