Cheap air horn

[PDA1]

The air horns that require the small canister are, in my case, famous for running out of "gas" just when I need them. Typically that happens on the 3rd of 5 blasts.

So I was looking for a alternative to the canister type horn and found a hand pump air horn on ebay here- Air Horn Hand Held Pump Airhorn Boating Sporting Events Emergencies Party | eBay

I bought one and was surprised how LOUD it is! (So were our neighbours)

For $6 it's perfect.

Man, it's loud.

Interesting, but "loud" is subjective.

It's also interesting that you run out of power with the conventional canister horns. I've only "used up" one in several years. They are only a backup for me, I have dual electric trumpet horns and they do the job. The portables are nice though in that you can aim the blast at the person whose attention you are trying to get.

110 dB is pretty loud.

The horn is perfect for my West Wight Potter 15.

Compact, no electricity or gas required.

I've seem then that screw onto an empty water bottle, loud as heck, but do these things meet USCG requirements?

I had one that screwed onto a empty pop bottle. I have 5 bridges to open to get to salt water. Got tired of pumping it up more than once just to get through the bridges.

On the plus side you'd get Popeye arms if you were ever out in fog.

123 dB is louder!

The problem with boat horns is, they are competing with a lot of other noise for attention. Think of the guy towing a wake boarder with his supersized stereo at full volume for example.

If what you bought suits your needs and any regulations, that's fine. A whistle might meet the requirements as well.

The OEM horns on most boats are totally inadequate.

We have one that you blow into. Plenty loud and as long as you can breath fine, it will continue to work.

In boat accidents most likely both boats have some God-awful loud air horns.

The real trouble is the operator isn't paying attention.

I have one of the exact same units. Two days ago it saved my boat from some serious damage.
There was a 50'+ trawler anchored nearby with a party on board in Boca Raton. When they pulled anchor they went into reverse and came right at us. A quick blast from that horn brought him to a stop, at which point the captain came rushing out the back to see what was up. He had stopped about 10 metres from us. He then proceeded in forward, away from us and left.
Without that horn I am sure he would have run right into us before even realizing he was in reverse.
