5 QUICK START
Basic Operation on Dry/Wet Sand
1
. S
et the Impulse controls to their preset positions, indicated on the faceplate
with a blue circle:
•
All Metal
mode
•
Volume
= 7
•
Sensitivity
= 4
•
ATS
= 8
•
Iron Reject
= NO EFFECT IN ALL METAL MODE
•
Pulse Delay
= 8
2.
Turn the detector on by moving the mode switch to the
Batt/Freq
position
and note the green light indicating a charged battery.
3.
Turn the
Mode
switch to
All Metal
.
4.
Adjust the
Threshold
for a slightly audible threshold tone.
5.
If the threshold tone is unsteady or noisy, refer to EMI noise section below.
6.
Happy Hunting.
Underwater Operation
Same as Basic Operation, except:
•
Delay
= 11.5 μs
Threshold
and/or
Volume
may need to be increased if headphones are submerged.
Maximizing Detection Depth
Same as Basic Operation, except:
•
ATS
= 0
•
Delay
= 7 μs
ATS
= 0 creates a slower response that is optimized for deep targets and requires a
slower sweep speed. As
ATS
is increased, the target response becomes sharper, with a
slight loss of depth.
Delay
= 7
μs offers the greatest sensitivity to all targets but can increase ground
noise, especially in saltwater. As Delay is increased, small/low conductor targets will
progressively drop out. With extreme care, 7 μs can be used in running surf but 8-8.5
μs is more stable.
