The NS3100 Multi is usually used with a through
hull depth transducer and a separate through hull
speed/temperature transducer. However, the unit can
take readings from another instrument, in which case
it may not need transducers (see section 8).
Through hull transducers generally give the
best performance and are the best choice for
displacement hulls. They are mounted in a hole
drilled through the bottom of the boat.
These accessories are available from your Northstar dealer.

Plastic through hull transducers are suitable for
GRP or metal hulls.
Bronze transducers are suitable for wood or
fibreglass hulls. Never install a bronze transducer
in a metal hull, because it will cause electrolytic
corrosion.
A range of Northstar through hull transducers
are available, plus in hull and transom mount
transducers. For more information, refer to the
Transducer Installation manual or consult your
Northstar dealer.
