1. RATCHET PINPOINTING - Pinpoint feature, automatically detunes for center location.
2. S.A.T. SPEED - Self Adjusting Threshold or Auto-tune, automatically maintains threshold.
3. TONE I.D. - Assigns each V.D.I. target number its own special tone or sound.
4. V.C.O. - Pinpoint or non-discriminate feature, increases pitch or tone with target strength.
5. MODULATION - Motion modes produce the same, or different volume, based on target depth.

6. AUTOTRAC
®
- Automatically updates Ground Balance during searching.
7. TRAC VIEW - TRACK appears on right side of display during AUTOTRAC

adjustments.
8. AUTOTRAC
®
SPEED - Dictates when AUTOTRAC

adjusts Ground Balance.
9. AUTOTRAC
®
OFFSET - Positive or negative AUTOTRAC
®
(over, or under kill).
10. TRAC INHIBIT - Prevents tracking the ground during target detection.
11. COARSE G.E.B. - (Manual Ground Balance) Coarse viewing, or overriding automatic.
12. FINE G.E.B. - (Manual Ground Balance) Fine viewing, or overriding automatic.

13. DISC. EDIT - Change V.D.I. (target reference numbers) accepted (detected), or rejected status.
14. BLOCK EDIT - Speeds EDIT by dragging ACCEPT or REJECT with ARROW controls.
15. LEARN ACCEPT - Target samples can be used to show or teach ACCEPT discrimination.
16. LEARN REJECT - Target samples can be used to show or teach REJECT discrimination.
17. RECOVERY SPEED - Speeds target responses, so close together targets each respond.
18. BOTTLECAP REJECT - How strongly the instrument rejects or breaks up on iron.
19. HOT ROCK REJECT - Degree the instrument is responsive to signals in the +95 (hot rock) category
20. SWEEP SPEED - Adjust signal sampling width thus the ideal loop/search coil sweep speed.
21. GROUND FILTERING - How much circuitry (high-pass filtering) used to separate ground/trash signals and targets.

22. VISUAL DISC. - Rejected V.D.I. numbers and ICONS do not appear on display.
23. ICONS - Graphic display representation of metal targets, ON/OFF.
24. V.D.I. SENSITIVITY - Response intensity to produce a display indication & 3rd V.D.I. digit@ 86 and higher.
25. D.C. PHASE - Measurement of ground, or metal target, during pinpointing.
26. GRAPH AVERAGING - SignaGraph
®
information collects over multiple loop passes.
27. GRAPH ACCUMULATING - Emphasizes common or predominate SignaGraph
®
.
28. FADE RATE - Clears or fades noncurrent SignaGraph

information (bars).

30. 2 FREQUENCY (BEST DATA) - Transmits and processes at both 3kHz and 15 kHz frequencies (salt eliminated).
Automatically chooses data from the most reliable frequency (based on both magnitude and phase) for each specific target.
31. 2 FREQUENCY (CORRELATE) - Transmits and processes at both 3kHz and 15 kHz frequencies (salt eliminated).
Compares data at 3 kHz and 15 kHz. Target signals that do not provide reasonably predictable information at both are automati-
cally rejected. Iron typically doesn't compare predictably between frequencies, improved iron rejection can be expected.
32. V.D.I. (NORMALIZED) - 2 Frequency modes (Best Data and Correlate) automatically have V.D.I Normalized ON as
it is required for these modes to operate predictably. Differences at 3 kHz and 15 kHz skew the well known traditional (6.59
kHz) V.D.I. chart/numbers painted on the top of the DFX control box. Normalization recalculates signals for this traditional
V.D.I. number chart. OFF expands/compresses portions of this V.D.I. scale (depending on the 1 frequency used.).
33. 1 FREQUENCY (3kHz) - Operates at 3 KHz providing for superior high iron mineral use (no salt present) particularly
for high conducting silver/copper alloys. Normalized ON maintains traditional (6.59 kHz V.D.I. chart/numbers. Normalized
OFF significantly expands higher end of V.D.I. chart/numbers compressing lower end of the scale.
34. 1 FREQUENCY (15 kHz) - Operates at 15 kHz providing in lower mineralized areas (no salt present) particularly for
lower conducting gold/nickel alloys. Normalize OFF significantly expands lower end of V.D.I. chart/numbers compressing
higher end of the scale.
