Buying Guide

Signal loudness (decibels)

Look for horns with clear decibel ratings—marine horns in this roundup include models around 122 dB for daytime visibility and lower but still effective outputs for short-range signaling

Power source: canister vs. 12V

Canister air horns (1.4–3.5 oz cans) provide portable, maintenance-free bursts while 12V trumpet horns deliver continuous, vehicle-style signaling and require wiring and power

Coast Guard compliance

Choose horns labeled or described as meeting marine signaling standards; compliant units ensure the tone and range align with safety regulations

Durability and materials

For saltwater use prefer stainless-steel or corrosion-resistant housings and weather-resistant fittings to reduce maintenance and corrosion risk

Package options and redundancy

Consider multi-pack canister sets or combining an air horn with an electric horn to provide redundancy if one system fails during an emergency
