Best Portable Air Horn ?

[Manateeman]

Looking for info on Falcon Commander air horn. Model FC4N.
It’s metal and loud. I can’t seem to find refills.
Falcon now just sells a different model with expensive refills.
I thought refrigeration refills would fit but not what I can find
Any opinions on a reliable and loud air horn?
Thanks in advance.

Have you seen the rechargeable ones? You pressurize the chamber with a bicycle pump.

I just get whatever they sell at West Marine. I also installed a speaker on my mast, hooked up to my VHF. That is mostly for fog horn purposes, but I have gotten on the PA and honked like a goose, if a goose were to honk five times.

Not a refill, but piercingly loud: the metal self powered (similar to the Sea Dog air horn at Defender) air horn. Never needs a refill and is not hard to blow. It can be heard from an astounding distance.

OK...I’ll extend the subject to air horns portable and fixed.
Three comments ?
I got an avalanche on the best salt shakers. L O L.
My manatee crew are rolling round the cabin offgassing on purpose asking if I can hear it topside.
The horror!
