Have you installed a power horn!

Topic prompted by recent boat security pic.
I’ve wanted to install a permanent electric horn for quick and easy, fast usage. There are some small hidden (unobtrusive) electric horns available. Are they adequate for the job of passage signals? I’d like to mount horn button on the pedestal.
How many of us use any signals? 1 beep forward, 3 beeps reverse

I just have an air horn ready at all times. I keep it in a cup holder attached to the pedestal. I can quickly aim the sound in the direction it is intended to pierce. I keep two onboard at all times.

I have tried both models of horns that you show on your graphic, both the horn-shaped one and the flush mounted one. In my opinion they just aren't loud enough. No one will hear them over the sound of their own motors, or yours, nor over the sound of the wind and waves. The only way to go on a boat is a compressor-powered air horn.

Right now I still have the flush-mounted horn, with a pedestal-mounted push-button. I use it to summon my boys from down below, but it's totally useless as a sound signal.

I'm thinking of a new VHF with a loud-hailing speaker, or a dedicated air-compressor horn system.

We have a loud hailer horn mounted on our “trawler mast” which is connected to our VHF radio. We also carry an air horn powered by a compressed air can. We have used and replaced the compressed air can several times. I have to read the manual every time I want to speak over the loud Hailer because we use it so infrequently. The radio will produce a foghorn noise at intervals over the loud Hailer also a horn noise. It’s simpler just to use can horn to get someone’s attention.

I have found this to be most useful as often the direction is behind me.

Certainly pleased worth the feedback. Hadn’t considered motor noise into equation. Not going the compressor/trumpet route ,but do have it on our power boat.
A couple cans it is.
