Best Cheap RC Submarine - Create Toys  

This little RC submarine is by far the best you can get for the money. Forward, back, turn left, turn right, dive, and emerge. The transmitter is also waterproof so no worries if you get it under the water too. It will work in a Hot Tub, so take it on vacation with you and use it either in a Hot Tub or Pool.
GearBest has them for under $20.
