AFI Stainless Steel Dual Trumpet Electric Boat Horn, 12 Volt, 110 dB

The AFI Stainless Steel Dual Trumpet Electric Boat Horn (model 10011) is a 12 volt marine horn built with a 100% stainless steel exterior and a type 304 stainless steel diaphragm, protecting the inner workings from harsh marine environments. Its compact dual trumpet design allows it to be installed in smaller spaces while still delivering an authentic two-tone marine horn sound. The horn produces a 110 dB rating at one meter, with a dual fundamental frequency of 420 +/- 20 Hz and 370 +/- 20 Hz for a richer, layered blast than a single-trumpet horn. Running on a 12 volt system, it draws a maximum of 7 amps. Measuring 16 inches long, 7.5 inches wide, and 4 inches high, it is sized for mounting on a wide range of vessels where a durable, weather-resistant horn is needed. The all stainless steel construction resists corrosion, salt spray, and UV exposure better than plastic-bodied alternatives, making it a long-lasting choice for boaters who want dependable signaling equipment.
