1 Introduction

The Explorer D310 measures and displays the depth
of the water. An installed Explorer D310 usually has
two parts:

The display unit.

A depth transducer, which is attached to the

hull and wired to the display unit.

The unit is powered from the boat’s power supply.

The Explorer D310 is part of the Northstar family of
instruments for boats, which includes instruments
for speed, depth, wind and repeaters. These
instruments can be connected together to form an
integrated data s ystem for a boat (see section 4).

For maximum benefit, please read this manual
carefully before installation and use.

How the transdu cer measures depth

The depth transducer generates an ultrasonic
(sound) pulse, which travels down through the

(backlit)

water. When the pulse meets the bottom, some of
the pulse is ref lected back up towards the boat and
is received by the transducer.

The display unit analyses the reflections from
each pulse. It removes unwanted reflections (from
bubbles and other objects) and calculates the
depth by measuring the time bet ween sending the
pulse and receiving its echo.

Cleaning a nd maintenance

Clean the display unit and any plastic transducers
with a damp cloth or mild detergent. Avoid abrasive
cleaners, petrol or other solvents.

When repainting the hull, cover or remove any
visible transducers. Depth transducers may be
coated with a thin layer of antifouling paint; gently
sand off any previous paint first.
