setting |
Block Edit |
-96 to +95 |
accept -40 to +94 accept +95 if no hot rocks gives more depth will
also make targets sound better.. if you can stand it |
Learn Accept |

On lets the disc reject targets that are swept in front of the loop |
Recovery Speed |
20 |
How fast a machine recovers for the next target to high a setting you'll loose depth
to low a setting and you get bad target separation |
Bottle cap Reject |
1 |
Higher numbers more iron rejection a setting of 1 makes nickels sound better |
Display
Visual Disc. |
Off |
Lets you see all the vdi numbers accepted or rejected |
Icons |

How sensitivity the display is to the target 86 and higher give 3 digit vdi |
D.C. Phase |
On |
Gives a dc phase vdi number for the target |
Graph Averaging |
On |
Accumulates targets on the display |
Graph Accumulate |
On |
Accumulates targets on the display |
Fade Rate |
11 |
How fast the display will fade or go down ,,, 0 resets after each target |
Signal (Transmit, Receive)
Transmit Boost |
On |
Usually on may be better for beach (saltwater) if off |

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 |
