Safety Technology 129dB Air Horn – Compact Personal Safety & Marine Signal Horn, US Coast Guard Compliant for Boats Up to 65 Feet, 5.13″ Handheld Design, 0.3 lbs, Multi-Use for Outdoors & Emergencies

129 Decibels of Attention — On Water or On Land Sound is one of the most effective tools for getting noticed. At 129dB, this air horn is louder than a chainsaw and approaching the volume of a thunderclap. It’s designed to be heard — across a lake, down a trail, or through a parking lot. Originally built to meet US Coast Guard marine signal requirements, this air horn serves double duty as a personal safety device, wildlife deterrent, and outdoor signal. It’s small enough to carry in a hand, a bag, or a boat’s storage compartment. Who This Air Horn Is For Boaters who need a Coast Guard-compliant signal horn for vessels up to 65 feet. Hikers and campers who want a wildlife deterrent that works on bears, coyotes, and other animals sensitive to loud noise. Runners or walkers who want a simple, non-contact way to draw attention if they feel unsafe. Also useful for coaches, event coordinators, and anyone who needs a loud, reliable signal that cuts through ambient noise without batteries or electronics. Is This the Right Choice for You? Choose the 129dB Air Horn if you want: A loud, non-contact way to draw attention or deter wildlife A US Coast Guard-compliant marine signal horn A compact device that works instantly with no batteries or charging Consider something else if you need: A reusable electronic alarm with continuous sound — this is a canister-based horn with limited bursts A defense tool with stopping capability — this creates sound only Why Sound Works as a Safety Tool Loud sound does two things: it draws attention from people nearby, and it startles anyone or anything causing a problem. At 129dB, this air horn accomplishes both in an instant. There’s no aiming required, no contact needed, and no learning curve. Press the button and the sound speaks for itself. For marine use, it meets the specific requirements set by the US Coast Guard for boats up to 65 feet. That’s not a marketing claim — it’s a compliance standard. If you’re on the water and need to signal other vessels, alert nearby boaters, or comply with marine safety regulations, this handles it. On land, the same 129dB output works as a deterrent for aggressive wildlife. Bears, coyotes, and mountain lions respond to sudden loud noise by retreating. It’s used by park rangers, trail workers, and experienced hikers as part of a broader wildlife awareness strategy. Quick Comparison: How Does the Air Horn Stack Up?

Frequently Asked Questions How many blasts does this air horn provide? The number of blasts depends on the duration of each press. Short, quick bursts will give you more uses than long sustained blasts. As a canister-based horn, it has a finite supply of compressed air. For marine and outdoor use, short signal bursts are standard practice and will maximize the life of the canister. Is it refillable? No. This is a sealed canister-based air horn. Once the compressed air is depleted, the unit is replaced. This is consistent with most portable marine signal horns — they’re designed for reliability and simplicity over refillability. Will it actually deter a bear? Air horns are recommended by wildlife agencies as one tool in a bear safety plan. The sudden loud sound startles most bears and encourages them to move away. However, no single tool is a guarantee in a wildlife encounter. It’s best used as part of a broader approach that includes awareness, bear spray, and proper food storage. Can I take this on an airplane? No. Compressed air canisters are generally prohibited in both carry-on and checked luggage by most airlines. If you’re traveling to a destination where you’ll need it, plan to purchase one at your destination or ship it ahead via ground transport.
