An elongated vibration generating device with a self contained vibration generating mechanism having its own power source including a battery driven motor, and eccentric weight and means to vary the vibration that can be easily attached to an ordinary fishing rod having a reel and line mounted thereon to cause the fishing rod shaft to vibrate in a manner to cause a bait or lure attached to the line to vibrate in a selective manner to attract fish. The device is firmly detachably attached to a fishing rod shaft by the co-acting combination of: (1) a soft and resilient extension depending from one end of the device and having a curvilinear cavity defined by a wall adapted to frictionally engage the top of a fishing rod shaft, and a first strap which is fixably attached at one end to the device above the extension wrapped around the fishing rod and the extension, with the other end of the strap adjustably secured to the fixed end of the strap by a hook and loop fastening system (2) a pair of spaced metal or hard plastic vibration-transmitting nubs depending from the device at the opposite end from the extension, adjacent the vibration generating mechanism, for self-aligning mounting on the rod, and a second strap fixably attached at one end to the device above the spaced projections, with the other end of the strap wrapped around the fishing rod and adjustably secured to the device by a hook and loop fastening system.
