CSI Pro™ 47
Tips for saltwater use:
Searching in a saltwater environment
is challenging for any Continous Wave (VLF) metal detector.
Saltwater is conductive and produces signals similar to foil.
Although the
CSI Pro
is not specifically designed for saltwater
use, it can be used in this environment.
Proper ground balance is the most important step for
stable saltwater operation. To achieve stable operation:
• First, Ground Balance the detector to the area that will
be hunted (see pages 16–18). Saltwater beaches
typically Ground Balance between 0 and 20.
• If necessary, reduce the Sensitivity until the signals
become stable.
• Swing the searchcoil flat and at a constant height.
Do not bounce the coil or lift the coil at end of swings.
• Swing the searchcoil parallel to the water's edge.
• The detector will be less stable in shallow, breaking surf
where the searchcoil is in and out of the saltwater.
In this area the detector is encountering a constantly
changing environment produced by the surf, making it
difficult for the detector to stabilize.
To improve stability, negatively bias the ground
balance by several points. To do so, press and release
the Ground Balance button and use the (-) NOTCH
DISC button to manually reduce the ground balance
setting. For example, if the Ground Balance number
was 11, reduce the Ground Balance number to 7 or 8.
Introduce only enough negative bias to achieve sufficiently
stable operation. Reduce the detector's Sensitivity as
needed.
Note:
While some background chatter may
remain, a target's more definitive response can be
recognized.
• If necessary, notch out the first pixel under Foil. It is
important to note that by notching out this pixel,
detection of some items will be reduced.
