Installing the
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.
