Nokta Simplex Ultra Gold Settings

Simplex Ultra is a 15 kHz single-frequency coin-and-relic detector, not a dedicated nugget machine. It can still find favorable shallow gold and jewelry.

Bottom line

Use All Metal or Field for favorable nugget ground; use Park/Beach for jewelry

Ground balance on clean soil, begin with stable sensitivity and a small/appropriate coil, then compare All Metal and Field. In mineralized goldfields or wet salt, recognize the limitations of 15 kHz single frequency.

Operating rule: Change one variable at a time and retain only repeatable improvements.

Method

Use a controlled workflow

Step 1

Separate nuggets/jewelry

Choose the site mode for the actual search goal.

Step 2

Ground balance

Automatic or manual balance must be completed on clean ground.

Step 3

Set stable sensitivity

Thirty levels allow fine reduction in noisy soil.

Step 4

Use open audio

All Metal threshold can expose weak responses.

Decision analysis

What actually changes the result

Fifteen kilohertz is versatile, not specialized for micro-gold. It can detect larger/shallow nuggets in favorable ground but should not be represented as a Gold Kruzer or PI substitute.

Ground Suppressor is not automatic improvement. Raising it can quiet difficult ground while also weakening borderline targets.

The 01–99 Coin & Relic ID scale is not a gold identifier. Natural gold shape and purity vary widely and overlap common trash.

FAQ

Seven questions specific to this page

Is Simplex Ultra a dedicated gold detector?

No. It is a 15 kHz coin-and-relic detector with useful open modes.

Which mode should I try for shallow nuggets?

All Metal for threshold information, then compare Field in trashier ground.

Does it have manual ground balance?

Yes. Nokta specifies automatic and manual ground balance.

What sensitivity range does it provide?

Simplex Ultra has 30 sensitivity levels.

Can it find gold jewelry?

Yes, but jewelry overlaps foil and tabs, so low conductors must remain accepted.

Is Beach mode ideal for every gold target?

No. Beach is for conductive sand; it is mainly relevant to jewelry rather than natural nuggets.

When should I choose a specialist gold detector?

For tiny nuggets, severe mineralization or serious prospecting where a higher-frequency or PI platform has a clear advantage.
