BEACH HUNTING
10
For beach hunting we recommend the operation of the detector in its
AUTO mode of operation. Lets start with the beach hunting on normal dry
beaches.
These beaches are easiest for searching, and allow the highest increase
of the sensitivity level, even switching to high of the high/low switch. Of
course, if there are no strong electromagnetic fields nearby. On the beaches
the most valuable finds are the golden rings, golden earrings, golden chains.
May be you know, but the thin golden jewelry is low conductivity, so not to miss
them we recommend the position of the
disc. control between relic and
coins . If you go further clockwise, beyond coins, the detector will start
rejecting the tiniest golden chains. If you want to ignore the thin jewelry, and
emphasize on coin shooting and search of higher conductivity jewelry you
could increase the
disc . control level, so that you start rejecting the most of
the foils. This will save you the scooping of unnecessary trash, but you’ll loose
the thin golden jewelry.
Searching on salt wet sand beaches . In such conditions to have a
smooth operation of the detector, with no false signals, first turn the high/low
switch to low . Then do not choose too high levels of the sens. control. And the
most important - while sweeping over the wet sand rotate the disc. control
clockwise until the parasitic signals, caused by the conductivity of the wet
sand, disappear. This rejection of the parasitic signals will be active after the
coins zone. To keep a good sensitivity to the targets in the wet sand it is very
important to stop rotating the disc . control exactly at the point where the
parasitic signals are rejected. If you pass this point you won’t hear any more
parasitic signals, but will reject some good targets.
Searching on black sands . These sands contain high percentage of
magnetic negative iron oxides. In such conditions many of the low
conductivity non-ferrous targets will look like ferrous for the detectors. That is
why we recommend you for black sand hunting to decrease the
disc. control
level. Remember that it is best to search in the AUTO mode of operation. It is
advisable also to switch to
low the high/low switch, and not to increase too
much the sensitivity level. Do not worry about the decrease of the level of
discrimination - on the beaches the ferrous targets are rarely met.
