Nokta Simplex Ultra Settings for Target ID
Simplex Ultra reports targets on a 01–99 scale at 15 kHz, with Field, Park, 4 Tone, 99 Tone, Beach and All Metal modes. IDs are conductivity clues, not object labels.
Bottom line
Use Park or 99 Tone to learn IDs; confirm doubtful targets in All Metal
Ground balance, set sensitivity below chatter and begin with minimal notching. Sweep known local targets to build a site chart, then use tone, ID range and repeatability together before rejecting anything.
Field setup
Starting points—not universal presets
| Situation | Mode / baseline | First adjustment | Check |
|---|---|---|---|
| Learning target behavior | 99 Tone | Minimal notch | Hear small conductivity changes |
| General park hunting | Park | Factory pattern | Simpler audio decisions |
| Iron-contaminated relic site | Field or 4 Tone | Iron Off only after listening | Cross-sweep clipped targets |
| Mineralized or uncertain target | All Metal check | Ground balance | Use threshold/ground response as context |
Adjustment method
Test the setting instead of copying it
Choose useful audio
Park for simplicity or 99 Tone for maximum conductivity detail.
Stabilize the machine
Ground balance and reduce sensitivity until falsing stops.
Calibrate locally
Scan real coins, tabs and foil on and in the soil.
Reject cautiously
Notch only repeatable nuisance ranges after measuring overlap.
Decision analysis
What actually changes the result
The 01–99 scale is not a composition analyzer. Similar conductive size and shape can place aluminum, gold and coins together. IDs typically widen with depth.
Notch is granular but not free. Simplex uses ID notches; removing nuisance bands silences every desirable object that lands there.
Target ID Depth affects when a number is displayed. It does not increase physical detection depth. A faint audio-only response may be legitimate even when the display withholds an ID.
FAQ
Seven questions specific to this detector
What is the Simplex Ultra Target ID range?
Nokta specifies 01–99. Treat it as a conductivity scale rather than a guaranteed object label.
Which mode is best for learning IDs?
99 Tone gives detailed audio across the scale; Park is simpler when you are new.
Does Target ID Depth increase detector depth?
No. It changes the depth/strength threshold at which the machine provides a visual ID.
Should I turn Iron Off on every hunt?
No. Hearing iron helps identify falsing, boundaries and mixed targets; silence it only when fatigue outweighs that context.
Why does a target give several adjacent IDs?
Depth, orientation, corrosion, ground minerals and nearby metal can spread the response.
Can I notch every pull-tab ID?
You can, but you will also reject desirable targets—especially gold jewelry—that overlap those IDs.
Is Beach mode required for dry inland sand?
Not necessarily. Use the mode that produces stable behavior; Beach is designed for beach ground response, not as a universal sand label.
