Caution
If the transducer hits larger objects or bottom, the transducer shaft may be bent, or
- in worst case - it can be broken off. A broken transducer shaft will cause water
leakage through the top of the shaft. If you suspect that the transducer shaft is seriously
damaged with holes, do not retract the transducer to its upper position.
To prevent serious damage to the vessel or the vessel stability, you must have a water
pump and a warning system in the sonar room.
Select the middle position carefully. The position is normally selected to place the
transducer just under the keel, but low enough to prevent echoes from the trunk. Once
the position is selected, make sure that the system protection functionality does not
inhibit transmission.
Procedure
1 Make sure that you have sufficient water depth
below the keel before you lower the transducer.
