The Ongaro Dual Trumpet horn has been chosen for the AutoHoot system because of its robust watertight construction. Made from 304 grade stainless steel throughout including the sealed sounder unit the horn will not corrode in saline conditions, making it the perfect choice for open sea start lines and large open water fleets.

With a rating of up to 125 db at 1 metre the Ongaro Dual Trumpet horn is one of the loudest horns on the market and the inclusion of a drain hole means that whatever the conditions sound will not be impaired by water accumulation ensuring the fleet hears the whole start sequence clearly.
