Quad Train Horn for Kobalt® 24v Battery

Sound is the one signal that works everywhere on the water. When you're swinging the boat back around to pick up a swimmer, or the kids have drifted past the buoy line and can't hear you yelling, a 130dB quad-trumpet blast settles it instantly. This horn clips onto the same Kobalt® 24v battery that runs your drill and impact driver at home — drop one in at the dock and you're set for the day.

• Four metal trumpets that produce a deep, train-style tone
• 130dB output — a blast that rolls right over ordinary vehicle horns
• Wireless remote triggers it from up to 160 ft; an available long-distance remote extends that to 2,000 ft
• Accepts any Kobalt® 24V battery — branded or aftermarket, any capacity
• Powder-coated finish, available in Black, Chrome, or Red
• Handheld, cordless, and fully pre-assembled — no installation, no wiring, no air tank to fill

Why Four Trumpets?

Quad trumpets are what give this horn its depth. Instead of a thin, single-note beep, you get a rich, layered air horn blast built so every note lands loud and clean — the kind of sound that carries across open water, down a trail, or over a crowd. The metal trumpets wear a protective powder-coated finish, so spray, dust, and rough handling in a boat locker won't wear it down.

The remote is where it gets fun. Stash the horn at the bow and fire it from the helm, or hand the remote to a spotter while the horn stays with the gear. Beyond the lake, it earns its keep as a safety signal in low-visibility conditions, an attention-getter at outdoor events, and a deterrent that convinces curious wildlife to keep moving.

Setup takes seconds: slide a compatible battery into the mount and the battery-powered horn is live. Nothing to bolt to a hull or a truck bed — it goes wherever the trip goes.
