Nokta detectors Velox One Quick Guide - Manual (Page 2)

Please note that signal audio boost should be used on a temporary or as-needed basis because it will not only boost the target signal audio but
it will also boost the loudness of ground noise and false signals. Therefore, it is recommended to keep the switch at position 1 and turn it to
position 2 or 3 only when you want to verify a weak metal signal and then turn it off again.
SIGNAL AUDIO BOOST
The signal audio boost switch boosts the sound of weak signals received from small or deep metals making it
easier for you to detect those uncertain targets.
At position 1, the booster is off. At 2, the signal audio will be higher and at 3, it will be heard at its maximum.
SIGNAL AUDIO
To avoid missing smaller and deeper targets, sweep the search coil both from right to left and left to right over each area you are scanning,
slightly overlapping the sweeps as you move forward.
When the device detects metal, it will produce an audible tone.
The device has 3 tone audio discrimination. The lower tone is for ferrous metals. For non-ferrous metals and gold, the device produces 2 very
similar high tones. In case of alloy detection the device may produce a high-low double-tone sound. In order to get familiar with the
different tones of your device, it is recommended that you practice with different types of metals and identify the sounds before you use it
out in the field.
NOTE: Discrimination, just like in any other metal detector, may not always be 100% accurate. There are many different factors affecting
discrimination accuracy. All metals based on their conductivity, shape, orientation underground, depth and ground mineralization are sensed
differently by a detector. Oxidized metals buried under ground for a long time such as tinplates and tins may produce gold like signals.
Following the experienced metal detector users' rule of thumb "when in doubt, dig" is the right thing to do.
SEARCHING AND METAL DETECTION
After the settings are adjusted, you can start searching by lifting the search coil 5cm. above
the ground and sweeping it right and left, keeping it parallel to the ground.
The device operates on the principle of motion. This means that you must move the search
coil over the target or the target over the search coil, in order for the device to see it. In other
words, metal detection is not possible without moving the search coil. 5cm
Coil cover use is optional. It protects the search
coil from scratches. If you want to use the cover,
attach the cover to the coil and press firmly on
the edges to secure.
Holding the metal pin pressed, insert the S-rod
into its place underneath the system box and
secure it by tightening the wingnut as shown in
the picture.
Again by holding the metal pin pressed, insert the
upper shaft into the S-rod and click the pin into its
hole. Then, secure it by tightening the twist lock.
Insert the extension shaft into the upper shaft
holding the metal pin pressed and adjust the
height by clicking the pin into one of the holes.
Then, secure it by tightening the twist lock again.
You may use the battery by attaching it to your
waistband as shown in the picture or to the side of
the system box using the optional battery case.
ASSEMBLY
Place the washers into the openings on both sides
at the end of the extension shaft. After placing the
shaft on the coil as shown in the picture, insert the
fastening screw through the hole and tighten it
using the wingnut.
Wrap the coil cable around the shaft all the way up
as shown in the picture and after inserting it in the
coil input socket underneath the system box,
secure it by twisting the connector. Pay attention
to not wrap the cable too tight during this step.
Plug the battery cable into the battery input socket
underneath the system box and tighten securely.
Assembly is completed.
