Other transducer types are also available for specific requirements. For
further details, contact your local Raymarine dealer.
For accurate speed and depth readings the transducers should be sited
within the clear water flow areas indicated by the shaded areas in the
following diagram.
The transducers should also:
• Be ahead of the propellers (by a minimum of 10% of the water line
length).
• Be at least 150 mm (6 in) away from the keel (ideally ahead of the
keel if a sailing yacht).
