Micro RC Submarine is one particualr toy RC appropriate to be used inside a bath tub, aquarium, or small pool. The SeaWolf Class Submarine is yet another pool or pond-sized sub designed to seem like real U.S. Navy subs. Obvious the swimming pool by having an RC Shark that even includes a controller that may go underwater.
You'll find rc models representing nearly any kind of full-size vehicle you could imagine (along with a couple of you can't). Including ships for underwater exploration. RC Submarines range in proportions from little tub or aquarium toys for in-home exploration to submarines that are as huge as your tub produced for offshore (or at the best deep lake) exploration.
