DEPTH 3100 Installation and Operation Manual

1 Introduction

The DEPTH 3100 measures and displays the depth
of the water. An installed DEPTH 3100 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 DEPTH 3100 is part of the NAVMAN 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 system for a boat (see section 4).

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

How the transducer measures depth

The depth transducer generates an ultrasonic

The DEPTH 3100 display unit

(sound) pulse, which travels down through the water.
When the pulse meets the bottom, some of the pulse
is reflected 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 between sending the pulse and
receiving its echo.

Cleaning and 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.
