Muče me nekoliko problema za koje se nadam da nisu kronične kod svih sa VLF detektorima.

Morska obala, pješčano-sljunčana mokra i vodljiva, NORMAL DISC.
pišti od od 0-8 nema šanse da nađeš mjesto bez signala kako bi mogao napraviti pripremu za GROUND ADJUST mod. probao sam nad vodom ali nema balansa do kraja skale, možda negdje griješim ali u u manualu piše
"provjeri teren sa NORMALNIM . modom ako nema metala prebaci na GROUND diži i spuštaj sondu , uz to pomići potenciometar balansa zemlje dok ne izgubiš signal. Na kopnu to mi uspijeva tek na osmici a inaće sa NORMAL DISC. ispod dva "hvata" zemlju, ma nije valjda crvenica tako teška mineralima zemlja???

Znam samo da je naš pjesak bogat feromagnetičnim zrncima jer sam ih znao kao klinac skupljati sa jakim magnetom,dva tri prolaza i imaš vrečicu zrnaca s kojim poslije možeš vizualizirati magnetske silnice.

Your 1270 gives you two ways to search in all-metal operation: (1) by setting
your NORMAL DISC to 0, or (2) by turning on the ALL METAL
GROUND ADJUST (rotate knob clockwise). When using the ALL-METAL
GROUND ADJUST mode, only the VOLUME and the SENSITIVITY controls
are still active: you have temporarily disabled the other controls on
the 1270 (it becomes the “primary” operating mode, as explained above). In
this mode, you must manually adjust the 1270 for the type of ground you
are searching. Turn the GROUND ADJUST knob switch on (to about “1”),
and the sensitivity to about “8”. Make sure the search coil is not near any
metal. This may be tested quickly by pulling the trigger switch and sweeping
over an area of about one square foot. If no signal is detected, release
the trigger switch and raise the search coil off the ground, and lower it back
down two or three times (also known as “bobbing”). If an audible sound is
heard, turn the GROUND ADJUST knob slightly clockwise. Repeat this
procedure until no sound is heard when raising and lowering the coil to the
ground. Once you have the 1270 balanced to the type of ground you are
searching, you may begin sweeping the coil at a comfortable pace.
