 Metal detector VLF-DD-1 for divers
The VLF-DD-1 industrial hand-held metal detector for divers
Introduction: The VLF-DD-1
is a multi-purpose industrial hand-held metal detector for divers that
can be used on many different bottom types. The applied electronics is
of exceptional quality that makes the VLF-DD-1 an easy to operate
device, where a number of functions are integrated for automatic
electronic adjustments. On the outside there are only the necessary
knobs or dials for optimal adjustment.
In the diving industry: Use as a semi professional or hobby detector possible?:
As a semi professional or hobby metal detector, the VLF-DD-1 is more
then suitable, thanks to the technically sophisticated high-quality
industrial electronics. It can be used for the detection of lost objects
underwater like jewels, coins and many other objects for example around
shipwrecks. Iron can not be rejected in spite of most standard hobby
metal detectors.
VLF-DD-1 FUNCTIONS "Tune" dial: In areas where the detector experiences interferences, the penetration depth or click rate can be reduced, even to almost zero. Interferences can be caused by, for example minerals that are part of the sea or river bottom, electricity cables etc. "DEL" dial
for rejecting
unwanted metals: Why a PULSE-INDUCTION detector ? Nearly all all-round land-mobile metal detectors are based on the so-called Induction-Balance technique. The VLF-DD-1 however is a so-called Pulse-Induction metal detector. This name describes the principle on which the functioning of the VLF-DD-1 metal detector is based on. Because of this, the
penetration capacity (maximum depth) of the average Pulse-Induction
based metal detector is much larger then that of an Induction-Balance
type detector (mostly more then a meter on relatively small objects) For hobby or
semi-professional purposes this detector can be very suitable for
archeological research of for example shipwrecks or for the location of
lost objects like coins, jewels etc. in recreational waters. Non Motion detector: The VLF-DD-1 has a so-called base tone or in other words an ongoing present click tone of approximately 5 X per second that builds up to a faster click rate and further to an ongoing continues tone, varying in frequency, depending on the shape, size and more of the object that is passed by the search antenna. Undesirable objects that are rejected with the DEL dial, will be ignored. Also possible undesirable bottom interference will be rejected.
Ground elimination: At some places, working with a metal detector is difficult or even impossible due to mineralization in the bottom, caused by iron oxide or other causes. When this is the case, the detector will react as if metal is present, while this is not the case. For this reason the VLF-DD-1 is equipped with a (partially) automatic ground elimination filter which adapt on nearly all bottom compositions. Where the Induction-Balance detector stops functioning due to bottom interference, the VLF-DD-1 will function further without problems.
Battery charger: The battery charger has a chip which ensures that the integrated rechargeable batteries can never be overloaded. The battery charger and rechargeable batteries are part of the standard package. Charging takes place from outside by means of a connector on the back of the detector. The rechargeable batteries remain in the detector during charging.
