This is a single-trumpet air horn kit from Marinco, driven by an electric compressor. The diaphragm is Lexan, which the maker calls non-corrosive, and the kit comes as a set with the compressor and its plumbing parts. The horn is rated at 120 dB at one meter in a 1/3 octave band, with a fundamental frequency of 315 Hz plus or minus 15. The compressor measures 2-5/8 inches across by 5 inches long and draws up to 20 amps at 12 volts.
Our take
The compressor draws up to 20 amps at 12 volts, so the wiring and fuse behind it have to be sized for that load. The horn itself is rated at 120 dB at one meter on a 315 Hz fundamental.
From our buying guide
A boat of 12 m or more must have a whistle, and one of 20 m or more a bell as well. Under 12 m it need not carry them, but must have some other means of making an efficient sound signal.
Check before you buy:
- You aren't comparing loudness across makers, since they measure it at different distances, or give no distance at all.
- You can mount a fixed horn facing forward and as high as possible, as Kahlenberg says to.
- You have any parts the maker leaves to you, such as a horn button and fuse.
