Abstract
A wireless fully submersible transmitter includes the substantially water-resistant casing within which there is located an audio frequency circuit, a radio frequency circuit, antenna, and a rechargeable battery. A microphone is connected through the casing between the inside of the casing and a position external the casing. A receiver includes a squelch circuit to eliminate the volume when the transmitter is submersed within water such that the RF signal from the transmitter is lost. The transmitter is operable from outside of the casing by a switch which interacts with an operable reed switch on the inside of the casing. An antenna is located inside the casing using the circuit board as the ground.
