The sens control is often thought of as a depth control and it is, but it can also
be used to make the detector more stable if interference caused by ground
mineralization or electromagnetic fields are experienced. If your detector is
quite nervous, noisy, please, decrease the sensitivity rotating the sens. control
counterclockwise. To get the best depth we would recommend to the most
experienced professional TH-ers with static coil to rotate
sens control clockwise until they hear rare, interrupted tones
from the speaker. When you start sweeping the coil these
tones will be oppressed by the ground, and you’ll hear the
useful responses from the targets in the ground.
NOTE: We recommend such an increase of the sensitivity
level only for the experienced professional TH-ers . For the
remaining operators we recommend to keep to the red
marked zones, and if they experience interferences to reduce
the sensitivity level.
For the professional TH-ers, who want to get the maximum sensitivity and
depth of their detector we could recommend the following:
Turn the detector off. Press and hold the
pinpoint button, and turn the detector
on. Thus you’ll enter the highest sensitivity mode of detector’s operation. The
detector will be extremely sensitive and deep, but it is possible on heavy
grounds, salty wet sands, near high voltage power lines to give you some
parasitic signals.
When testing the detector in built-up places, where there are many
electromagnetic interferences, you won’t be able to increase too much the
sensitivity level. That is why the tests of the real parameters and qualities of the
detector should be made in field conditions.
If the detector is slightly noisy, before decreasing the
sens.
level try with a change of the operation frequency (from freq.1
to freq.2 or vice versa) and check whether the detector has
become less noisy.
The normal position of the
freq.1/freq.2 switch is the freq.1,
and it is for 13.89 kHz operating frequency. If there are
interferences received you could choose the frequency,
where the detector is less noisy. The frequency switch
positions are designed to eliminate the radio-frequency
interferences mainly in competition hunting or when searching
in close proximity to another detector with a similar operating
frequency.
