The horn has a 304 grade stainless steel diaphragm and mounting bracket to prevent corrosion in marine environments. The twin horn effect provides a loud blast for a small unit. This model is compact so it can be mounted out of the way on the bow or cabin top your boat.
All electric horns meet the American Boat and Yacht, Council (ABYC) Regulation Number A-23 for boats up to 12 meters. All AFI Air Horns meet U.S. Coast Guards C.O.L.R.E.G.S. and US Inland Navigation Rules, Annex II Regulations for boats up to 20 meters.
