Transducer

Thru-hull mount
The installation position of the transducer directly affects the performance of the trans-
ducer. For best performance, keep the following points in mind when selecting the
mounting location.
• Select a location where the influence of water flow and air bubbles is minimal.
• Select a place least influenced by engine noise.
• Do not install the transducer inboard.
• For FRP vessel, do not cover the transducer with fiberglass, to prevent damage to
the transducer if the temperature rises.
• Bottom slope angle less than 24°
The illustration below is the transducer with fairing, and was created by the Airmar
Technology Corporation. The BOW mark (arrow) on the fairing and the triangular re-
cess should be facing the bow.
