Once you have located fish, the PowerRay's precision bait drop can be utilized to lure them closer.

Tie the bait drop to the fishing line of your rod, placing the hook at the end. Attach the bait drop to the PowerRay and swim to the selected location where you wish to fish. 

Press the bait drop button (in the center of the remote controller, under the speed switch) to release the bait. The sinker will drop, taking the hook with it. Then, simply wait for the fish to be drawn in.
