How well do you know the proper sound and light signals for your size vessel for periods of reduced visibility? Now, how often do you send out that signals? Trying to signal manually while also operating your vessel while in the stressful conditions of fog can be areal challenge. This package, the Signal Mate from Kimberlite Assemblers in Baltimore, can be placed on the bow (well-secured, of course) and it will automatically send the necessary sound and light signals, leaving you free for more important tasks.
From the press release: Signal Mate from Kimberlite assemblers is a fully automatic, waterproof controller producing all sound and light signals required by the U.S. Coast Guard Navigation Rules. It is specifically designed to enhance boating safety in conditions of restricted visibility and emergency situations such as engine breakdown, sail/rigging damage or flooding. An especially valuable piece of equipment for cruising yachts and sailboats involved in offshore racing.
Signal Mate is turned on in fog and automates the required light and sound signals. This frees the helmsman and crew to focus on the safe navigation of the vessel.
