This device is simple to use and IGFA allowed. It works on a principle that has proven to attract Mako Sharks. Just hook it up to your 12-volt boat battery, place the transducer in the water and the device is automatically activated - that's it! It is now emitting a rich tone, while acoustically vibrating the water in a 360-degree pattern. You are now being heard a minimum of 1 mile under water. The rocking motion of the ocean further activates additional circuitry and breaks up the tone by adding an intermittent harmonic. Since this device emulates baitfish, it should be caged, or it will be eaten. The sound is heard by game fish as an invitation to a slow-moving, wounded meal. That means a greater selection of game fish caught. Supply the standard 12 volts from your boat's electrical system and place transducer over board, or can be mounted within the bottom of the boat.
