1.7 Optional Triducer 524ST-MSD, 525ST-MSD
The triducer is designed for thru-hull mounting.
Mounting considerations
When selecting a mounting location keep the following points in
mind:
• Air bubbles and turbulence caused by movement of the boat
seriously degrade the sounding capability of the transducer. The
transducer should, therefore, be located in a position where wa-
ter flow is the smoothest. Noise from the propellers also ad-
versely affects performance and the transducer should not be
mounted nearby. The lifting strakes are notorious for creating
acoustic noise, and these must be avoided by keeping the trans-
ducer inboard of them.
• The transducer must always remain submerged, even when the
boat is rolling, pitching or up on a plane at high speed.
• A practical choice would be somewhere between 1/3 and 1/2 of
the boat’s length from the stern. For planing hulls, a practical
location is generally rather far astern, so that the transducer is
always in water regardless of the planing attitude.
