Three trumpets fire at 880, 820, and 780 Hertz for a layered blast that carries over wind and engine noise. The compressor, relay, tubing, and mounting brackets all come in the box, so you've got everything to wire in a serious signaling horn.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eThe Hella Marine 003001671 is a triple-tone air horn kit built to cut through wind and engine noise out on the water. It's a three-trumpet setup that fires at 880, 820, and 780 Hertz all at once, so you get that layered, chord-like blast that carries a lot farther than a single tinny electric horn. Everything you need to wire it in comes in the box. The compressor, the relay, the tubing, and the mounting brackets are all there.\u003c\/p\u003e\n\u003cp\u003eHere's the thing about air horns on a boat. A stock horn is fine for a polite toot at the fuel dock, but when you need to be heard, a real compressor-driven trumpet horn is a different animal. This Hella unit pushes air through three separate trumpets tuned to slightly different frequencies. Those three tones stack up into a fuller, more attention-grabbing sound. On a powerboat under 30 feet, where the tones carry cleanly over the wind, it's genuinely loud and hard to ignore. That's exactly what you want when you're signaling intentions in a channel or getting someone's attention in a tight anchorage.\u003c\/p\u003e\n\u003cp\u003eLet's talk about the sound for a second. The three frequencies, 880, 820, and 780 Hertz, sit close together on purpose. When they blend, your ear hears a rich, slightly dissonant chord instead of one flat note, and that texture is what makes the horn read as urgent and easy to locate. A single-note horn can get lost in ambient noise. Three tones stacked together don't. It's the same idea behind big truck air horns, scaled and tuned for a boat's 12-volt system.\u003c\/p\u003e\n\u003cp\u003eInstall is straightforward if you plan the wiring. The compressor pulls a healthy amount of current on startup, so give it a dedicated circuit. We run a 30-amp fuse and 10-gauge wire to the compressor, and we let the included relay do the switching so the dash button only carries the trigger signal, not the full load. Wire it that way and the relay stays cool and the horn fires cleanly every time. Skip the relay or undersize the wire and you'll cook something eventually.\u003c\/p\u003e\n\u003cp\u003eMount the compressor and the trumpets somewhere solid and dry. The brackets in the kit handle a flat console or bulkhead mount easily. If you're going onto a flybridge rail or a hardtop, the stock brackets can come up a little short, and it's an easy fix with a piece of quarter-inch aluminum angle. Mount the relay on a rigid surface away from the compressor so vibration doesn't make it chatter. And keep the air tubing runs smooth. Avoid sharp kinks, clamp the barb connections, and the air path stays sealed for the long haul.\u003c\/p\u003e\n\u003cp\u003eThe trumpets are molded plastic finished in painted red, which keeps the whole assembly light and rust-free. Plastic means no corrosion, and that's a real advantage in salt air where a chromed steel horn would start weeping rust in a season. Give the mounting ears a stainless backing plate if you're bolting to a spot that sees a lot of engine vibration, and they'll stay put.\u003c\/p\u003e\n\u003cp\u003eWhat's in the box matters too, because a lot of horn kits leave you sourcing parts. This one is complete. You get the three-trumpet horn assembly, the air compressor that feeds it, the relay that handles the switching load, the air tubing that connects compressor to trumpets, and the mounting brackets for both pieces. Add a fuse, a length of appropriately sized wire, and a momentary switch, and you've got everything for a clean install in an afternoon.\u003c\/p\u003e\n\u003cp\u003eWho's this for? Center consoles, bay boats, walkarounds, and smaller cruisers that need a serious signaling horn and have 12-volt power to run a compressor. It wires into any 12-volt system. Pair it with a simple momentary push button at the helm and you've got a proper, loud, three-tone horn that answers the need for an audible signaling device. If you run a sailboat and want a horn mainly for close-quarters signaling, the layered tones are still effective, they just shine brightest on a powerboat where they punch through the wind.\u003c\/p\u003e\n\u003cp\u003eHella Marine builds this the way they build the rest of their line. Quality materials, a fit-and-forget mindset, and a design meant to keep working season after season. Wire it right, mount it solid, and this little three-trumpet kit will be answering the helm button for a long time.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003eTriple-tone output at 880, 820, and 780 Hertz for a layered blast that carries over wind and engine noise\u003c\/li\u003e\n  \u003cli\u003eThree molded trumpets keep the sound full and easy to locate across the water\u003c\/li\u003e\n  \u003cli\u003e12-volt compressor-driven design delivers real volume, not a thin electric beep\u003c\/li\u003e\n  \u003cli\u003eComplete kit: compressor, relay, air tubing, and mounting brackets all included\u003c\/li\u003e\n  \u003cli\u003eIncluded relay handles the switching load so your dash button only carries the trigger signal\u003c\/li\u003e\n  \u003cli\u003ePainted-red plastic construction stays rust-free in salt air where chromed steel weeps rust\u003c\/li\u003e\n  \u003cli\u003eMounting brackets fit flat console or bulkhead installs right out of the box\u003c\/li\u003e\n  \u003cli\u003eHella Marine fit-and-forget engineering for season-after-season reliability\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cdiv class=\"nvn-trust\"\u003e\n  \u003ch2\u003eWhy Buy from NVN Marine\u003c\/h2\u003e\n  \u003cul\u003e\n    \u003cli\u003eAuthorized Hella Marine reseller, full manufacturer warranty\u003c\/li\u003e\n    \u003cli\u003eNMEA member and ABYC certified, advice from real boat techs\u003c\/li\u003e\n    \u003cli\u003eSame-day shipping before 3 PM ET on in-stock items\u003c\/li\u003e\n    \u003cli\u003eNY headquarters and Fort Lauderdale flagship retail store\u003c\/li\u003e\n  \u003c\/ul\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cdiv class=\"nvn-faq\"\u003e\n  \u003cdetails\u003e\n    \u003csummary\u003eWhat makes this a triple-tone horn?\u003c\/summary\u003e\n    \u003cp\u003eIt has three separate trumpets tuned to 880, 820, and 780 Hertz.
