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 seri-
ously degrade the sounding capability of the transducer. The trans-
ducer should, therefore, be located in a position where water flow
is the smoothest. Noise from the propellers also adversely 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 transducer 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 loca-
tion is generally rather far astern, so that the transducer is always
in water regardless of the planing attitude.
