Spectrum XLT Settings Definition Sheet

Basic Adjustments

Target Volume: Sets the desired loudness of a target response.

Audio Threshold: Sets the desired loudness of the threshold (background hum).

Tone (Audio Freq): Adjusts the tone (pitch) of the threshold (background hum).

Audio Disc.: All Metal Mode or Discriminate mode.

Silent Search: No threshold (background hum) or threshold (background hum).

Mixed Mode: Discrimination (A.C.) response or All Metal (D.C.) and Discrimination (A.C.) response.

A.C. Sensitivity: Discrimination sensitivity.

D.C. Sensitivity: All Metal and pinpoint sensitivity.

Backlight: 0 is off, 1-6 is on at different brightness levels.

Viewing Angle: Adjustment makes the display easier to see at different temperatures.

Pro Options

Audio

Ratchet Pinpointing: Automatically detune the loop when pinpointing.

S.A.T. Speed: Adjust the threshold autotune speed only in no discriminate or mixed mode, has no affect in discriminate mode.

Tone I.D.: Identifies targets by assigning each VDI # a seperate tone.

V.C.O.: In All Metal or pinpoint mode, target response will increase in loudness and pitch as coil approaches target location.

Absolute Value: Big Foot coil option.

Modulation: Gives full volume on all targets, shallow targets may break up a little. This option is forced on when Silent Search is selected.

G.E.B. / TRAC

Autotrac: Turns the autotrac ON or OFF, this is good for maintaining a fixed ground balance point.

Trac View: Allows users to see when the detector autotracs.

Autotrac Speed: How fast the detector will adjust to the ground when autotrac is ON. Autotrac Offset: Can add a positive or negative offset to the ground balance point.

Trac Inhibit: Allows the cancellation of ground tracking overs targets.

Coarse G.E.B.: Adjustment of the coarse G.E.B. (turn autotrac OFF when using).

Fine G.E.B.: Adjustment of the fine G.E.B. (turn autotrac OFF when using). Coarse and Fine G.E.B. are used to manually ground balance the detector. Before using these adjustments, the autotrac feature needs to be OFF. Then you adjust the Coarse and Fine settings until you are close to no variation in sound between the air and ground when the loop is lifted and lowered.

Discrimination

Disc. Edit Accept & Reject: Allows VDI numbers to be accepted or rejected one at a time.

Block Edit: Allows VDI numbers to be accepted or rejected in groups by scrolling. Learn Accept: ON allows targets swept in front of the coil to be accepted by the VDI number the detector reads.

Learn Reject: ON allows targets swept in front of the coil to be rejected by the VDI number the detector reads.

Recovery Speed: How fast the detector recovers for the next target reading, too high of a setting and depth is lost, too low and target separation sensitivity is lost.

Bottle cap Reject: More iron rejection at a high setting, nickels tend to sound better at lower settings.

Display

Visual Disc.: Allows the display of all VDI numbers rejected or accepted when targeted. Icons: Allows the display of icons that represent the targets detected, OFF tends to speed up the display response.

V.D.I. Sensitivity: How sensitive the display is to the target detected, above 85 gives a three digit VDI number.

D.C. Phase: Gives a D.C. Phase VDI number for targets detected.

Graph Averaging: Averages the target VDI hits for the display.

Graph Accumulating: Accumulates target VDI bars on the display instead of clearing out before displaying next target.

Fade Rate: How fast the displayed target VDI bars fade from the display, 0 resets the display after each target.

Signal

Transmit Boost: Usually ON, may be better as OFF when searching a saltwater beach or black sand.

Transmit Frequency: Can be changed to alleviate interference from other detectors operating at the same frequency or possible interference from electrical sources.

Preamp Gain: Adjustment of the sensitivity, higher settings affect both AC and DC sensitivity
