A true noise canceling microphone with outstanding sound quality that can withstand the harsh marine environment. A special membrane is used on both sides of the diaphragm which allows air, but not water, to enter. This allows the microphone to cancel noise that is more then 1/4 in. away. Racket such as air, bubbles and breathing noise are virtually eliminated. This is especially noticed when using a full face mask with an oral-nasal cavity.

Designed to be robust, the membrane is designed to allow a user to take the mask off at the back of the boat while in the water.  In the past, microphones being exposed to sea water or to water while cleaning had a short life, not so with the Hot Mic. The Hot Mic element can withstand a differential pressure of about 12 feet. In OTS's tests, several dives were made to 35 feet and the AGA full face mask with a Hot Mic was removed.  After putting the mask back on and clearing it, communications were fine.

The Hot Mic will give you the finest intelligibility available and last for months with little maintenance.

The ME16R Microphone element has the following specifications:

• Membrane is designed to allow a user to take the mask off at the back of the boat while in the water
• Can withstand a differential pressure of about 12 feet, which means if a diver takes off the ffm at the back of the boat and drops down to 15 feet, the membrane will not be able to keep the water out and the microphone element will be damaged.
• If you expose the Hot Mic® at any depth down to 130 feet and come up, no damage will occur.
