What underwater air-driven horn do you use?

[applecorps]

Seems like it's getting harder to find a reliable underwater horn driven by a low pressure hose. The ones being sold are too often cheaply made and perform badly.

So, please weigh in with your suggestions!

Thank you,

Curious - why do you need one?

 

[Aviyes]

Because the use of one tends to lead to it mysteriously jumping overboard during the surface interval.

 

[EastEndDiver]

Because those big underwater semi trucks move to slow.

It's much easier to get a groups atention by blowing it then by wawing your hands while everyone is watching that pretty morray eal.

Quack quack....one DM we had the other day had one...I thought it was a toad fish

I much prefer the screams of the person whose life is being choked out of them for disturbing the peace with one of those effing things.

Come on, get with a program, cars have it, boats have it, trains have it...

Suggestions? don't buy another one. Whose attention are you hoping to get? you can't tell direction of sound under water, so I am not sure what it would accomplish other than scaring the fish and pissing off other divers. Buy a tank banger, much cheaper and easier for me to ignore...

Well, I guess from the above comments that I should be embarrassed to admit that I have one
First of all, a tank banger isn't going to get the attention of the dive boat ignoring where I am in the water,
though fortunately I haven't had to use it on the surface.
Under water you do not need to depress the button all the way to get the attention of someone. A short partial sounding is like a burp and is no more annoying any other sound.
I rarely use mine, but in Belize we had one DM more interested in scooting way ahead to kill lion fish than pointing things out. The other divers in the group appreciated that I had a means of getting his attention back to stuff we were looking at. Just a short burp of low pitched sound redirected his attention. Yes, a tank banger would have worked but useless on the surface, and I'd have to carry something to bang the tank with.
On another dive someone got way low on air. As I was preparing to share air I gave a more prolonged and louder blast to get the DM's attention that we were going to need to ascend.
I consider the horn to be a low profile safety device.
