FW 3
FW 3 is a foghorn with high mechanical resistance and low energy consumption. The foghorn is made of corrosion-resistant aluminum to withstand the harsh marine environment. FW 3 is approved by the USCG (United States Coast Guard) up to 0.5 miles (805 m). Thanks to the small but powerful amplifiers, the FW 3 is among the smallest foghorns in its size on the market.
