User’s Guide

In this channel, the All-Metal Sensitivity setting is basically

an additional gain setting applied to the all-metal signal above

and beyond the Rx Gain setting. The following graph shows a

signal with both a low setting (black trace) and a high setting

(gray trace). The higher sensitivity setting improves target sig-

nals, but it also increases the amount of audio noise and can

make VX

more “chattery.” This is especially true when EMI is

present.

All-metal audio can be presented in one of two ways: VCO,

and non-VCO. This selection is found at Audio Search

All MetalVCO:

Tip: In the normal all-metal mode, SAT (self-adjusting

threshold) is applied so if you hold the search coil steady

over a target, the audio response will fade away on its own.

In pinpoint mode, SAT is not applied so you can hold the

search coil steady over a target and the response will

remain steady.
