User Manual

Thank you for purchasing the VK40 metal
detector from VIKING. This is one of a family
of microprocessor driven metal detectors
that are very simple to use yet provide
excellent performance.

Please take time to read this booklet. It will guide
you through each of the available features to
ensure you get the best out of your detector.

Getting Started

1. Unpack The Detector

There are two main sections. The 'S' shaft, onto
which is mounted the control box, and the lower
shaft with the search head. Note the spring
button near the end of the lower shaft.

2. Assemble The Detector

Slide the lower shaft into the 'S' shaft, wrapping
the cable snugly, but not tightly, round the shaft.
When correctly aligned the spring button on the
lower shaft will click into 1 of the 3 holes on the
underside of the 'S' shaft.

3. Tighten the coupling

Turn the coupling to the 'lock' position as
indicated by the arrow. This makes a rigid
connection between the two parts of the shaft.

4. Insert Battery

The detector takes a single PP3 (alkaline) 9V
battery. This is placed in the battery
compartment on the rear of the control box.

ENSURE THE BATTERY IS INSERTED THE
CORRECT WAY ROUND

Push the drawer back into the detector until it
clicks. Please note the drawer can only be
inserted the one way.

Your detector is now ready for use

To disassemble the detector, loosen the coupling
by turning it against the arrow and push in the
spring button. The lower shaft will now slide out
from the 'S' shaft.

Detection Modes

The VK40 offers 3 methods of detection:

Motion Mode

When operating in motion mode the search head
must be kept moving to enable an object to be

detected. In this mode the detector is silent until
an object is detected when it emits a sharp beep.
The sound occurs as the centre of the search
head passes the target object. This is the only
detection mode that provides discrimination.

All-Metal Mode

This mode provides a continuous faint audio
threshold tone, allowing the smallest signals to
be detected. In this mode the audio output will
continually, but slowly, retune to the threshold
level preventing the detector from drifting out of
tune, but requiring the search head to be kept
moving to detect items. This mode is not
available when detecting in Beach mode.

Non-Motion Mode

Similar to the All-Metal mode, this mode also
provides a faint audio threshold through the
speaker or headphones. In this mode the
detector does not automatically retune, but
enables the search head to be held stationary
over the target to allow accurate pinpointing. In
some cases changes in ground conditions and
temperature may cause the threshold to vary
from its faint preset level. In this case the
detector needs to be retuned,

Membrane Keypad

All the VK40's functions are controlled from the 5
keys on the front panel of the detector. Please
read this section carefully to understand how
these controls operate with each other.

Pressing this key once will turn the
detector on. When the detector has com
pleted its startup sequence and is in
detect mode, pressing this button again
will turn the detector off.

▼ When the detector is operating, this key

will switch from the current detection
mode to Motion mode. When the detector
is in Menu mode, this button will decre
ment the currently selected setting.

P When the detector is in either Motion or

All-Metal detection modes, holding this
key will switch the detector into Non­Motion mode until the key is released.
This allows for accurate pinpointing.
When the detector is working in Non­Motion, holding this key retunes the
audio threshold to its preset level.

▲ When the detector is detecting in Motion

mode, pressing this key will switch to All­Metal mode. Subsequent presses will
alternately switch the detector between
Non-Motion and All-Metal modes. When
the detector is in Menu mode, this key
will increment the currently selected
setting.

MENU This key switches the detector into Menu

mode, allowing the Sensitivity, Discrimination
and Ground settings to be adjusted and the Auto
Power Off feature to be enabled or disabled.

Detector Setup

The VK40 provides a menu system to alter the
detector settings which can aid with detecting.
These settings are: Discrimination, Sensitivity
and Ground. The effect of changing the value of
each of these is described below:

Discrimination

The Discrimination setting is used to alter the
detectors ability to ignore unwanted metal
objects when used in Motion mode. The higher
this setting, the more discriminating the detector
will be. When set at 0 all metal items will be
