Attwood Marine Bellows Signal Horn, Lung-Powered, 110 dB, USCG Rule 33

Overview

The Attwood Marine 2460-7 is a lung-powered bellows signal horn that gives you a 110 dB sound signal without any battery, CO2 cartridge, or Freon. It meets U.S. Coast Guard Rule 33 (Annex III) and Federal/EPA regulations, and its 8 in. height by 3-1/2 in. width makes it easy to keep with onboard safety gear.

This is a straightforward handheld option for boats that need a portable horn that is not tied into the vessel's electrical system. It works well where quick access matters, such as near the helm, in a cockpit locker, or in a grab bag for small craft and tenders.

Key features

• Lung-powered bellows horn with 110 dB output
• Meets U.S. Coast Guard Rule 33 (Annex III) and Federal/EPA regulations
• No batteries, CO2, or Freon to replace or monitor
• Portable 8 in. x 3-1/2 in. form for easy stowage on board
• Useful where you want an audible signal without adding a 12V or 24V circuit

Compatibility and fit

This horn suits skiffs, tenders, inflatables, paddle craft, and sailboats, and it also makes sense as a backup sound signal on larger boats. There is no wiring, fuse protection, switch panel space, or network integration to plan around, so fit comes down to keeping it in a spot that is easy to reach underway.

Use on board

Because it is powered by breath, it stays ready after long periods in storage and does not depend on shore power, battery condition, or a working horn circuit. For day boats and open boats where space is limited, that can be a simple way to keep an audible signal close at hand.
