The Minelab SD2200v2
5.
Operation
These instructions can be followed by operators who are familiar with the
workings and general terminology of detectors. However, Minelab
recommends that as the
SD2200v2
has new features and some of the
functions can differ from similar functions of other detectors, all operators
should read the Operating Instructions in section 5.2.
5.1
Quick Start Instructions
a) Switch the
Power
switch to
On
.
b) Set the
Threshold
control so that sound can be heard in the
headphones.
c) Hold the detector at waist height with the shaft horizontal, so that the
coil is vertical. Keeping the coil vertical, slowly move it around your
body through a half-circle
until the noise from interference is loudest.
Hold this position, keeping the coil motionless, and push the
Tune
button
once to start tuning function. Tuning takes approximately one minute.
A series of three beeps indicates that the best frequency has been
selected.
d) Rotate the
Tone
control to produce a threshold pitch that suits your
hearing.
e) Set the
Channel
switch to
Both
and the
Audio
/
Boost
switch to either
Shallow
for small shallow targets,
Deep
for large, deep targets or
N
(Normal) for general detecting. (see section 5.2.7)
f) Set the
Iron Discriminate
switch to the
Disc
position and turn the
Level Adjust
to the middle of its range.
g) Ground balance the detector by pulsing the coil up and down and,
while coil is in motion, flick the
Balance Mode
switch from
Fixed
to
Track
.
h) Your detector is now ready to be used.
Minelab recommends that you take time to read this manual thoroughly to
help get the most out of your new
SD2200v2
.

Operating Instructions
This section gives a detailed description of how to operate the
SD2200v2
detector. The section Detector sounds contains definitions of some terms
with which the beginner should be acquainted.
5.2.1 Detector Sounds
Threshold:
This is the background sound produced by the detector. The
loudness of the background sound is set with the
Threshold
control. Set
this so that it can just be heard. The pitch of the threshold sound can be
set to your preference using the
Tone
control.
Object signal:
This is an abrupt change of the pitch and volume of the
threshold sound. If the pitch drops first, then rises as the coil is passed
over a target, this generally (but not always) indicates a small target. If the
pitch rises first then falls as the coil is passed over a target, this generally
indicates a large target. The pitch variations can be different when operating
in
Disc + ID
mode (see section 5.2.9).
Ground noise:
These are irregular noises that are difficult or impossible
to pinpoint when moving the coil over the ground. They are caused by
changing chemistry or mineralisation of the ground. While the detector is
in
Tracking
mode these effects are minimised.
5.2.2 Turning on the SD2200v2
Hold the coil away from the ground and metal objects and switch the
Power
switch to
On
.
Note:
When the
SD2200v2
is turned off, it saves important information
(like last tuning and ground balance settings) in its internal memory. If
detection is started in the same spot, the user should not have to re-tune
or re-ground balance the detector.
5.2.3 Set the Threshold Control
The
Threshold
control should be set so that background tone is barely
audible. It is important to note that small surface objects, as well as
large deep objects, will produce very small changes in the threshold
sound.
It is therefore important to set the
Threshold
control correctly to ensure
that these targets are heard. We suggest that you experiment with known
targets to assist in setting this and the other controls to suit your hearing.
