Best location for the transducer
FIGURE 1: Recommended installation locations for a transducer
A flat-bottom hull provides the best environment for mounting the trans- ducer: It provides a horizontal surface and a constant water flow over the transducer, with little turbulence (see Figure 2 for the recommended transducer incline angle). If the vessel has a deadrise angle greater than 5 degrees, mount the transducer on a fairing block to create a horizontal surface and keep the transducer perpendicular to the waterline (see Figure 3). You must order the fairing block, if needed, from the trans- ducer’s manufacturer.
