BEACH HUNTING
7
For beach hunting we recommend the operation of the detector in its normal
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. Of course, if there are no strong electromagnetic fields
nearby. On the beaches the most valuable finds are the gold rings, gold
earrings, gold chains. May be you know, but the thin gold 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 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, we recommend you decrease
the sensitivity level. 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 a high percentage of
magnetic negative iron oxides. In such conditions many of the low
conductivity non-ferrous targets will look like ferrous to the detectors. That is
why we recommend when hunting black sand that you decrease the
disc .
control level. Remember that it is best to search in the normal mode of
operation. In such conditions it is advisable to use low levels of sensitivity
and discrimination - the AMD position of the
disc . control. Do not worry
about the decrease of the level of discrimination - on the beaches the ferrous
targets are rarely met.
