The parts for the standalone configuration, listed above.
Through hull depth transducer. Transducer Installation manual.
5-2 Other parts required
One or more 310 series instruments will be connected to the boat 12 V power supply via:
An accessory switch to turn the instruments on and off.
A fuse. Use a 1 A fuse for between one and five instruments.
Optional external beepers or lights can be fitted. The Explorer D310 output is switched to ground,
30 V DC and 250 mA maximum. If the beepers and lights require more than 250 mA, fit a relay.
For systems of several instruments, wiring and connectors are required (see section 4 or the NavBus Installation and Operation manual).
5-3 Transducer
The Explorer D310 is usually used with a through hull depth transducer. However, the unit can take readings from another instrument, in which case it may not need a transducer (see section 4).
A through hull transducer generally gives the best performance and is the best choice for displacement hulls. It is mounted in a hole drilled through the bottom of the boat.
A plastic through hull transducer is suitable for GRP or metal hulls. Plastic through hull transducers are not suitable for solid wooden hulls (use Northstar’s bronze transducers).
A bronze transducer is 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.
