The Minelab SD2200v2
6.2.3 Vehicle battery charger
·
The car charger supplied with the
SD2200v2
will charge the detector
battery from the cigarette lighter socket of your motor vehicle.
·
Plug the charger into the cigarette lighter socket and turn the ignition
switch to Accessories. This supplies 12 volt power to the cigarette
lighter socket. This voltage is reduced by the charger to 6 volt output to
charge the detector battery.
·
A red LED will flash while the battery is charging. When the battery is
flat the LED may flash fast enough so as to appear constantly on, as
the battery charges the LED will flash at a slower rate. Leave the battery
to charge for approximately 10hrs using this charger.
·
If the battery voltage of your vehicle drops below 11 volts, the charger
will stop charging. This stops the battery charger from flattening the
vehicle battery.
CAUTION
The 12 volt charger is designed for use with vehicles which have a
negative earth electrical system. Most cars made after 1970 will
have a negative earth electrical system. If you plug the charger into
a vehicle with a positive earth system, the fuse in the cigarette
lighter plug will blow and the LED will not light.
CAUTION
DO NOT
leave the mains charger on for extended periods as
reduced battery life can result

Detecting Techniques
7.1
Searching
The
SD2200v2
is a motion detector, which means that it must be moving
in relation to a target in order to detect it.
DO NOT
set your shaft length too
short. If the coil is too close to your body it may detect your pick, the
battery
,
or any other metal that you may be carrying.
Note:
DO NOT
wear steel cap boots or shoes with metal eyelets when
detecting.
If you find that you are getting false signals as you sweep the coil, check
that they are not produced by any metal that you are carrying. Move the
coil closer and further away from your body to determine if the signals are
coming from items such as your pick or the battery. If the signals are from
these items you must increase the distance between them and the coil.
The coil should be swept over the
ground in a side-to-side motion.
As the operator moves slowly
forward, the search pattern
resembles a snaking path. To
ensure that the ground is
thoroughly searched, it is
advisable to approach the area
from three directions as shown
in figure 8.
While sweeping the coil it is
important to keep it parallel to
and at a constant height from the
ground at all times. The easiest
way to achieve this is to have the
coil lightly brushing the ground.
Be aware of any tendency to
raise the coil at the ends of each
sweep as this will reduce the
detection depth (see figure 8).
