Electromagnetic Interference (EMI)

EMI can be a problem with any wide-band metal detector,

whether a multi-frequency VLF or a pulse induction design.

includes a frequency offset to help deal with this. Select the

Transmit Frequency item on the Live Control Bar to access the

Offset control:

There are 5 increments of frequency offset; with the search

coil held in the air, find the one for best stability.

Menus & Controls

has a number of configuration settings with 2 ways to

access them:

• Live Control Bar — Live-search settings

• Menus — All settings, suspends operation

When the

MENU button is pressed during normal search the

Main Menu appears. We will cover all the menu settings in sub-

sequent chapters.

Tip: If VX

seems to have an erratic audio only when

sweeping the search coil on the ground, check the

ground balance.

Tip: EMI is easiest to hear in pinpoint mode (trigger

pulled).

Tip: If VX

continues to have erratic audio with the

search coil held in the air, reduce the RX Gain.
