Compact twin-tone electropneumatic horn engineered specifically for sea vessels. Perfect for small/medium sail and motor boats. Stylish Italian design allows for external viewable mountings (ex: on rollbars, etc…). Finished with “nautical white” high-grade anti-yellowing ABS. More water proof than Nautilus Compact, it features an intricate maze system for the protection of the “anti-water spray” air intake. High decibel power and pleasant pitch that only an air horn can offer (115 dB(A) at 2 meters – 139 dB(A) at 4 inches, 530 + 680 Hz). Simple and fast assembly, does not require external air tube connections. Requires only a single fixing point thanks to its all-inclusive design. Because of its style, this important instrument compliments well the other accessories normally present on sea vessels (antennas, radar, etc..). For other characteristics see “Nautilus Compact”.

Keep this in mind: sound energy doubles for every 3 points you go up in the decibel scale. It means that the Stebel which produces 139 dB of sound, puts out a LOT more sound than these popular horns:
– 800% of the sound energy of the more expensive FIAMM Freeway Blaster

– 600% louder than the 130 dB Pro Pad Mini Beast horn;
– 650% louder than the 128dB Rivco dual trumpet horn.
