A2-2. Through-hull installation
Transducer installation of CVS-841/851 is only possible with through-hull installation. Various types of
rectifying tanks (Turbulence Minimizing Enclosure) are prepared according to the material of the ship’s
hull or transducer frequency used. Mount the rectifying tank to the ship’s bottom before mounting the
transducer to in the rectifying tank. The more the tank protrudes, the less the water turbulence. The
following drawing illustrates an example of the through-hull installation.
