1.3 Installation of transducer
1.3.1 Transducer installation
The transducer should be installed in a location free of bubbles and away from disturbed water flow. Smooth water flow around the transducer and along its surface are very important for consistent operation. Areas in the center of water line length at cruising speed are usually satisfactory. Forward of the engine and in a flat area near the center line of the boat are preferred. Do not install the transducer behind water intakes, other through-hull fittings or irregularities in the hull.

Water Line length

High water line Flat water line
Low water line (See NOTE)

Keel Line
The transducer must be installed off the keel line, either port or starboard side.
NOTE: High water line: Water line when vessel pitches up most. Low water line: Water line when vessel pitches down most.
Figure 1.6 Recommended area of transducer installation
1.3.2 Through-hull installation
Transducer installation for CVS-702D 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.
