AI-33-523-01 - Fairing block for Airmar B258 DT transducer

The Airmar AI-33-523-01 fairing block is a critical component for any B258 DT through-hull transducer system. Its role goes beyond simple protection: it is fundamental to the hydrodynamic performance of the transducer, particularly on deep-keel hulls or high-speed vessels. Without a correctly fitted fairing block, a through-hull transducer cannot operate effectively, generating turbulence that degrades the signal and limits the accuracy of depth and temperature readings, especially at high speeds.

Installing this fairing block requires careful attention. It must be precisely cut and fitted to the boat’s specific keel angle. While this step demands skill and the right tools, it is crucial. Once properly installed, it ensures that the B258 DT transducer, with its 1 kW power and 50/200 kHz frequencies, can deliver its full potential, providing clear and reliable bottom and fish detection. It is particularly recommended for sport fishing boats and medium-sized commercial vessels (9 meters and above) where signal quality under all sailing conditions is paramount.
