Is there a way, that I can communicate with a Raspberry Pi, that is underwater. The depth of the Raspberry Pi will be about 20 meters or less. I was thinking of using Bluetooth, or 433Hz RF Transmitter or other such sensors, but I am not too sure, if they will work. My goal is to have a transmitter and receiver with the Raspberry Pi, and I will have a controller that has transmitter and receiver as well, but I am not sure what transmitters and receivers, or if any, will work on the Raspberry Pi.

A good General rule of thumb, is if it will work on an Arduino Due or Zero (those are the 3.3 volt Arduinos I know of), it will work with a Pi.
Another solution is, if the Pi is tethered for power or something else, is to run a physical cable carrying whatever you need transmitted.
