Nokta detectors Velox One Quick Guide - Manual

QUICK GUIDE
TURNING ON THE DEVICE
To turn on the device, rotate the On/Off knob to ON. Turn the same knob to OFF position when you want to turn
off the device. When the device is turned on, a melody will be heard and approximately 10 seconds later you will
hear a long beep indicating that the device is ready to use.
The device will provide more depth at on position. However, to better discriminate ferrous metals, using the
device in mineral modes and the iron discrimination at maximum position is recommended.
GROUND BALANCE
Especially in mineralized ground target signal is negatively affected by the ''noise'' caused by ground
mineralization. This situation may prevent the detector from getting a clean signal from the target necessary for
metal detection and accurate discrimination. Ground balancing is a process through which the metal detector
is able to cancel out the negative effects caused by ground mineralization.
To ground balance, holding the search coil 5cm. above the ground, sweep it right and left, keeping it parallel to
the ground and slowly turn the ground balance knob clockwise until the noise is gone and the device is silent.
If you cannot ground balance the detector, gradually decrease the sensitivity and repeat the above steps.
For maximum depth, do not turn the ground balance knob to the right more than necessary. Generally
speaking, the mid-level (between 4 - 7) offers the most ideal and stable detection capability on different types
of ground without sacrificing depth.
As the ground balance goes into the right area, the device will start losing depth for some non-ferrous metals except for gold. When the
ground balance setting reaches the maximum point the device will detect iron and gold but it will not detect some non-ferrous metals.
If you are searching on a ground loaded with mineralized stones or dips and holes, it is recommended to ground balance over one of these
stones or the holes.
In areas of very high mineralization, ground balance may not be sufficient. In such a case, you may need to use the mineral search modes.
SENSITIVITY
Sensitivity setting is used to eliminate interferences caused by electromagnetic waves in the surrounding
environment or ground noise. Electromagnetic waves may result from power lines in the surrounding
environment or from the operation of electrical devices, radars, wireless radios, and even TVs.
Sensitivity is also the depth setting for the device. Therefore, especially in high mineralization, it is
recommended that you lower it only if the device is still getting noise after you adjust all the other settings
(ground balance, iron discrimination and mineral modes).

IRON DISCRIMINATION
This setting is designed for tough ground conditions and experienced users. For normal ground conditions or if
you do not want to bother with this setting it is recommended that you keep it at the factory setting (FS).
This setting has 2 main purposes:
1) Especially in areas of high iron mineralization and wet beach sand you may not be able to ground balance the
device. In such a case, you can use iron discrimination. By turning the iron discrimination knob to the right, you
can enable the ground effect to be reflected as iron and eliminate it by turning the iron switch off.
In general, when searching in wet salt water beach sand, the most ideal settings are the maximum level of the iron discrimination, iron switch off and
mineral 2 or 3 modes. You can also use these settings when searching in wet plowed land with high iron effect.
2) It enables metals containing iron to produce a low tone and to be discriminated more easily. Discrimination starts at about level 4 - 6. Below this
level, all metals including iron will produce a non-ferrous (high) tone and generally speaking the device will perform at its maximum depth. In
addition, iron switch will not be active below this level.
As mentioned before, especially on grounds with high iron content such as wet salt water beach sand and wet plowed land, it is
recommended that you search in mineral 2 or 3 mode, bring the iron discrimination to maximum level and turn the iron switch off.

MINERAL MODES
Mineral Modes: If you are searching on high mineralized ground (extremely salty soil, wet beach sand, wet
plowed land or highly magnetic ground conditions) you may not be able to ground balance the device. In such
a case, first turn the On/Off knob to mineral 1. If the device is still getting noise, turn it to mineral 2 or mineral 3.
This will eliminate the noise and false signals caused by mineralization. However, you may experience a
decrease or fading in the signal obtained from certain metals at maximum depths.
IRON SWITCH
When you want to avoid detecting ferrous metals you can turn the iron switch off and enable the device to
eliminate these metals and not produce a warning tone.
NOTE: Many metals considered to be trash may not produce a ferrous metal signal. For example, pull tabs may
be sensed as a non-ferrous metal by most detectors because their signal is very similar to that of gold.
