I buy the cans!! I hate the eletric they never last!! I have a whistle but just for show, when I came near sinking in ruff weather I blew the dam thing it was a Joke!!

does anybody ever use those things anyway? my old bayliner, years ago, had a sticker on the dash with all the horn signals. i tried signaling a few times, ya know cause i had a horn and a sticker, and people would shoot me the bird and yell obscenities at me. bout as useless as a flare gun. all you can do is set there and drink beer and blow the horn at and shoot flares at all the boats that go by and wont stop to help

Sports whistle with the ball bearing inside, very very loud.

Got an old set of horns out of a f150 at the junk yard a while back, still haven't installed them in the cuddy, I'm a Chevy guy and it just doesn't feel right.
