Use the PowerRay Bait Drop to position your baited hook when fishing with the Power Vision PowerRay underwater remotely operated vehicle. The Bait Drop, offered here in a pack of five, attaches magnetically to the underside of the PowerRay and drops free at the touch of a button on the ROV's remote control. Made of electromagnetic soft iron, with a diameter less than that of a penny and weighing less than four ounces, the Bait Drop is designed with a lip that makes attaching your fishing line easy.
