Standard Horizon Submersible Speaker Microphone

The Standard Horizon Submersible Speaker Microphone Model MH-73A4B is designed for serious boaters, anglers, and commercial mariners who require reliable two-way communication in harsh marine environments. This submersible unit provides full water resistance, ensuring that it can withstand the rigors of marine use without compromising audio clarity or operational convenience.

Constructed with a sealed, submersible housing, the MH-73A4B integrates both speaker and microphone functions into a compact unit, reducing deck clutter and eliminating the need for extra cables. Its rugged design is built to endure saltwater environments and the daily handling that occurs on fishing vessels and patrol boats. Weighing only 0.4 lbs and measuring 5 x 3 x 7 inches, it is easy to mount in various locations where operators need hands-free communication access.

This microphone is an ideal upgrade for Standard Horizon radio systems already installed on recreational and commercial vessels. Experienced captains and crew will appreciate the submersible design, especially in rough-water conditions where traditional microphones may fail, making it a reliable choice for tournament fishing, offshore patrol operations, or extended hours on the water.
