Description
(Gold detecting Modes: 1 - 15)
(Beach Mode: 16)
The MODE function matches the search coil t
o the detector’s receive
circuitry.
If the mode is increased, the sample delay time is also increased which
decreases detection distance on tiny targets but also improves ground
handling ability.
Some search coils may need a higher or lower mode number to run
better in certain grounds, with good target response, e.g.
•
MODE 1
has the shortest sample delay and provides the best
performance in less mineralized ground with a small coil on
small targets.
•
MODE 15
is best used in extremely mineralized ground to help
reduce ground feedback noises at the cost of losing some
smaller targets.
Note: Some coils may require increased MODE if adjusting the DELAY cannot
achieve GROUND BALANCE.
Select the appropriate level of
MODE
setting reflecting the size of coil
to be used, the target size, soil depth and level of soil mineralization
anticipated.
•
Use SMALL coils for fine/tiny gold in shallow ground with MODE
setting #1 to #8.
•
Use medium coils for small and large targets setting mode to
suit the coil and the ground.
•
Use LARGE coils for large deep gold with MODE settings say
#8 to #15
Beach Mode
Mode 16 is used for beach detecting and operates with
no
ground
balance and all targets produce a rising pitch signal.
Tip:
Use the lowest MODE
number the ground will
allow
Tip:
If the ground is very hot
or changeable don't
hesitate to
increase
MODE to 15 as testing
has shown that doing so
has little impact to
detection distance
(<30%)
