This is a joke, right? (LOL)

Actually, except for the fish-finder part, it's not a new idea. Salt-Water Big Game Fisherman have been using remote control boats to take out heavy baits for shark and other behemoths, for several decades. We used to do it in Galveston back in the 60s. Any remote control model boat would work. You just layed the bait on the deck, opened the bail on your reel, and when it gets where you want, just close the bail and your bait would fall off the back end of the boat. Simple.

If you really wanted to have fun, you could use a remote control helicopter model, or maybe a dive-bomber like an SBD Dauntless or TBF Avenger. If your gonna use toys, make 'em good ones!!!! I have a neighbor that has built a remote control 4 engined B-29 model that actually drops projectiles. You could make precision bomb runs with your lures.

Semper Fi!
