Nokta Simplex Ultra Settings for coins
Simplex Ultra provides Park, Field, 4 Tone and 99 Tone choices, 30 sensitivity levels, adjustable recovery and 01–99 IDs. Coin settings should match trash density and local coin alloys.
Bottom line
Begin in Park; use 99 Tone to learn conductivity and 4 Tone for faster decisions
Ground balance, start with the factory Park pattern, set sensitivity below chatter and test a local coin beside common trash. Raise recovery only until separation becomes repeatable; preserve low conductors if jewelry also matters.
Field setup
Starting points—not universal presets
| Situation | Mode / baseline | First adjustment | Check |
|---|---|---|---|
| Modern park, moderate trash | Park | Factory recovery first | Stable sensitivity |
| Mixed coins and jewelry | 99 Tone | Open discrimination | Learn low/mid conductors |
| Fast cherry-picking | 4 Tone | Measured notch only | Accept that some valuables overlap trash |
| Sparse historic field | Field | Lower recovery after testing | Slow overlap and wider acceptance |
Adjustment method
Test the setting instead of copying it
Select the audio job
Park for simplicity, 99 Tone for detail, 4 Tone for defined bins.
Balance and stabilize
Ground balance and control EMI before editing rejection.
Test separation
Place a coin beside iron or a pull tab at realistic spacing.
Log local IDs
Use recovered coins to build a site-specific range.
Decision analysis
What actually changes the result
99 Tone gives information, not extra detection depth. It maps conductivity more finely through audio, which helps experienced users hear target variation.
Recovery speed trades signal duration for separation. Faster is useful in adjacent trash; slower can strengthen isolated responses. Test rather than maxing it.
Coin & Relic ID Scale is a reference aid. It does not turn the 01–99 conductivity response into a guaranteed object label, especially on deep, corroded or mixed targets.
FAQ
Seven questions specific to this detector
Which Simplex Ultra mode is best for coins?
Park is the simplest baseline; 99 Tone adds conductivity detail and Field suits cleaner historic ground.
What recovery speed should I use?
Start at the mode default and increase only until a coin beside trash separates repeatably.
Should I notch pull-tab IDs?
Only if coin-only recovery matters more than jewelry; tabs overlap desirable low and mid conductors.
Does 99 Tone detect deeper than Park?
Not automatically. It changes audio resolution, while ground, recovery, sensitivity and coil control govern practical performance.
What sensitivity is best?
The highest of the 30 levels that stays stable enough to hear faint repeatable targets.
Should I ground balance in every park?
Balance when soil response is audible or conditions change; do not copy a fixed number from another site.
Can Target ID identify the exact coin?
No. Alloy, depth, angle, corrosion and nearby metal can shift its 01–99 response.
