Orion 509 8 oz Air Horn | 120 dB Marine Signal
Orion 509 8 oz Air Horn | 120 dB Marine Signal — Product description
The Orion 509 is a compressed-gas air horn that does one thing well: it's loud. A 120 decibel single-tone blast at 10 feet, up to 106 blasts from the 8 ounce can, and no batteries to worry about. It's the simple sound signal you want aboard for docking, hailing, and getting seen.
The Orion 509 is a compressed-gas air horn built for one job: making noise loud enough that other boats hear you. A 120 decibel blast at 10 feet, single tone, off an 8 ounce canister. Press it and it goes. No batteries, no charging, no fuss.
Every boat needs a way to make a sound signal. The Navigation Rules ask for it, and a good horn covers it. When you're backing out of a slip in a crowded marina, rounding a blind bend, or trying to get the attention of a boat that hasn't seen you, one press of this horn does far more than a shout ever will. It's the kind of gear you hope you never need in an emergency, but you're very glad it's aboard when you do.
The 8 ounce canister is good for up to 106 blasts, so a single can lasts most boaters a season or more of normal use. The horn trumpet threads onto the canister, and the whole thing is small enough to stash in a console cubby, a ditch bag, or a life-jacket pocket. Keep it somewhere you can reach it fast, not buried under the anchor rode.
A few honest notes. This is a single-tone horn, so you get one clean, loud blast, nothing fancy. It runs on an HFC-152a gas canister, which is the consumable part. When a can runs low you'll notice the blast getting weaker and shorter. That's your cue to swap in a fresh canister rather than counting on the last few puffs. Store it upright and out of direct sun, and it'll be ready when you reach for it.
For recreational boats, PWCs, sailboats, and dinghies alike, it's the simple, reliable signaling device that just works. Toss one aboard and forget all about it until the day you actually need it.

Frequently asked questions
How loud is the Orion 509 air horn?
It puts out a 120 decibel single-tone blast measured at 10 feet. That's plenty loud to be heard over an outboard and across a busy harbor.
How many blasts do I get from one can?
Up to 106 blasts from the 8 ounce canister. For most boaters that's a season or more of normal docking and hailing use.
Does it need batteries or power?
No. It's a compressed-gas horn, so there's nothing to charge and nothing to fail. Press the button and it sounds right away.
Will this cover the sound-signal requirement for my boat?
The Navigation Rules require every boat to have a means of making an efficient sound signal, and a loud handheld horn like this is the common way recreational boaters handle it. Check the requirements for your boat size and waters.
Can I replace just the canister?
Yes. The 8 ounce canister is the consumable part. When the blast starts getting weaker and shorter, swap in a fresh can rather than relying on the last few puffs.
How should I store it?
Keep it upright and out of direct sun, somewhere you can grab it fast. A console cubby or the top of your ditch bag beats burying it under the anchor rode.
