Thanks all for your responses, and love your horns Mark, I just can't cost justify it and don't have available air. So likely I will go with a duel trumpet electric all stainless model. AFI does claim to have the loudest electric at about 128 db I believe. Any other electrics out there in use that are loud and have a good tone??

Imagine hearing Mark's horn in thick fog, you would think you had the QM2 bearing down on you.
Luckily, we don't have much in the way of fog over here, so a standard single trumpet model gets us through marine regulations, never used it in anger. Well, that's not quite correct, when the kids were young, it was their favourite toy, much to my mounting frustration(that and grabbing the lower helm while I was on the flybridge steering with the upper helm, that's definitely off-putting)

Like Andy, I just have a single electric trumpet horn thingy, and when you have the horn switch on, which I routinely do...just in case some yobbo doesn't know the rules of engagement...to fire the beastie one presses the button marked horn, and it goes BLAAAAARGH...
Of course so far I only get to use it at midnight on 01/01 at the fireworks up the Brissy river...that's fun.

Guests often suggest inappropriate uses of Coot's horn. I rarely comply.

Normally use the horn at least twice each outing: both entering and exiting the marina:
(Is that tug going to exit with the barge? Yes, she did; here at high tide, while failing to signal.)

Hand held air horn and electric horn. The only vessels that sound signals here are the ferries leaving the landing. That's a good thing in my opinion.
FWIW, the IMO regs have whistle frequency characteristics. Lower the frequency, bigger the vessel. You're not really supposed to sound like a ship, unless you are a ship....

Someone needs to inform Kahlenburg. They have size ranges listed on their website showing what regulations their horn covers. Mark's seemed within "spec" to me (according to their website) and it is obviously low frequency.
Frankly Spy I was wondering if there was a regulation somewhere covering horn tone and db level.

Kahlenberg used to have a chart on its Internet site showing volumes and frequencies for variously-sized boats/ships. I wouldn't worry about it if one selects a horn in the "yacht" category. For volume, the rule was "not less than."

AusCan: while Australian state regulations don't specifically require an electric or air horn, all DO require a vessel to have a sound signalling device on board: could be a bell, a whistle, a horn...but you do need something that will make a noise. At least in NSW, it has to be good for 2nm hearing.
I have used an air horn while chartering in Alaska when the proper horn on a Grand Banks packed it in. Lots of fog over the 3 weeks we were there..a single can lasted fine and was plenty loud enough. To answer the OP, your can-of-air is plenty good enough functionally...but reading between the lines you really want something 'loud and pretty', don't you? The Kahlenberg air horns are the bees knees: I have a single trumpet air horn but if I win the Lottery, a Kahlenberg is on the list. Absolutely not a necessity....but what a blast !

Saved money by dropping the teak-deck option and getting a Kahlenberg.

I just picked up a Grover Products horn at a sale for ten bucks. It had dirt dobber nest inside ,took it apart and cleaned it up put it back together and tried it out at home with my shop compressor ,loud low tone .It's 24 " long with 6" bell tapering down to 3/4" tube. It's a truck horn and it's their trombone series. I like the sound . I'm working on how I want to hook it up. I was thinking of a small 110 compressor with 1-1/2 gallon tank.I'm not sure if this will give me enough volume.What do you guy's think? Having air on the boat can be handy.

My original dual 12v, 2003, gave out last year. I replaced it with a dual 12v West Marine. I surprised how loud and the nice tone of it. Very different from the numerous electric horns I have owned before. I thought about air but don't want to give up the space for compressor, tank and so on. I have owned the air horns which just use a small compressor but the ones I have had a shrill tone.

I've had some bad luck with electric Ungaro horns. They are suppose to be quality but my experience is that they require constant maintenance due to moisture intrusion. They are mounted at about a 30 degree downward angle and still require periodic disassembly, drying out, sanding points, WD40 and reassembly.

I've never seen fog here other than up in the hills, and with such little boat traffic I don't feel the need for a horn. Actually - I can't ever recall a boat of any type sounding a horn in these parts.
I do have a whistle on all lifejackets though, and a ships bell, although you may need a good ear to hear either at 2 nm.

I have AFI twins and I think they are plenty loud enough. When I blow them, my wife reports immediately to the galley to prepare a snack.

I better have a closer look at my horns then. I didn't know about this function. Something must be wrong with them.
Was this perhaps an upgrade?

Yes. At cruise it was awfully hard for her to hear me snap my fingers.

If you'd like a loud deep and pleasant toned air horn without spending a ton, you might consider a Fiamm Fultone II. $170 on eBay. Ours sounds great - never heard anything even close on a boat our size.
