VDI vs. TDI

[mtsheron]

Are these the same thing on the Deus or am I missing something? I mean is the VDI the reading or TID you get under the different frequencies or can someone explain?

THank you for any clarification from the knowledgable Deus pro's here!

Not sure this is what you mean, but:

The readout is a measurement of the targets conductivity. It changes depending on what frequency you use UNLESS you tick the ID NORM option - which I do. 3.0 and later versions...

Here is a link explaining it (see red text).

I'm certainly no expert since I have only just begun to use the detector.

I copied this from another website; not sure of its accuracy, but nevertheless here it is:

Target identification (TID)

Target Identification is closely related to discrimination. Modern discriminating metal detectors can tell you if the target is a copper penny (minted before 1982) or a zinc penny. It can tell between a silver dime (minted before 1965), and what we call a “clad” dime, one that is a composite of copper and nickel.

The output of the discrimination circuitry can be an audible tone, with a high pitched tone for valuables and a low grunt for junk. This is called tone identification. The output is more commonly a meter reading, or a numeric value called a VDI number which appears on a screen. VDI stands for Visual Discrimination Indicator. Discrimination output sometimes uses multiple modes to alert the operator. A high-pitched tone will indicate a high-conductivity target, while the LCD display shows both a VDI number and a probable target. On White’s metal detector, for example, a nickel might appear as “VDI = 18 Nickel” on the display, or “VDI = 80 Dime, Penny.”

Target Identification is not always accurate. The error rate tends to go up when the target is deeper in the ground.
