Nokta Simplex Ultra Best Settings
There is no single best setting for the Simplex Ultra - it depends on your ground and target. A solid start: a stock search mode (Park or Field), sensitivity as high as you can go without chatter, a moderate recovery speed, and ground balance to your soil. From there, tune tone breaks and discrimination to the targets you want.
Pick the right search mode first
The Simplex Ultra ships with preset search modes that cover most situations. Start here before touching anything else:
- Park / Field - general coin and relic hunting on grass and soil.
- Beach - wet and dry sand, where salt needs taming.
- All Metal - maximum depth and sensitivity when you want to hear everything.
Run the stock mode for a few outings before you start customizing. It teaches you how clean ground and real targets sound.
Sensitivity and recovery speed
Owners often ask about the tradeoffs of higher versus lower sensitivity. The rule of thumb:
- Raise sensitivity until the detector starts chattering, then back it down a notch or two. More is not always better - too high just adds false signals.
- Use a faster recovery speed in trashy, target-dense ground to separate signals; slow it down in clean ground for a little more depth.
- Keep the coil low and sweep slowly and overlapping - technique matters as much as any menu value.
Ground balance, tones and discrimination
Ground balance the detector to your soil (use the automatic routine) whenever you move to new ground or get excess noise. For audio, the Ultra lets you set tone breaks so different target ranges get different pitches - useful if you hunt sites with a specific target in mind, such as separating iron from non-ferrous. Adjust discrimination to notch out the trash IDs you keep digging, but go carefully: aggressive discrimination can mask good targets that sit near iron.
Common problems and fixes
- Constant chatter or falsing - lower sensitivity and re-run ground balance.
- Erratic IDs - slow down your sweep and keep the coil closer to the ground.
- Can't tell targets apart before digging - learn the tone IDs in a test garden with known coins; this is the single biggest skill jump for new users.
Where to go next
Settings are only half the picture - knowing the machine helps too. See the full Simplex Ultra overview and the Simplex Ultra review for context, and the Simplex manual hub for the official documentation. For buyers still deciding on a kit, the WHP bundle adds wireless audio.

Frequently Asked Questions
What is a good sensitivity setting on the Simplex Ultra?
Turn it up until you hear chatter, then back off slightly. The highest stable setting for your ground gives the best depth without false signals.
Do I need to ground balance the Simplex Ultra?
Yes, especially on mineralized ground or when you move sites. Run the automatic ground balance routine to cut noise and stabilize target IDs.
How do tone break settings help?
Tone breaks assign different pitches to different target ID ranges, so you can hear iron, foil and good non-ferrous targets as distinct tones - handy when you are hunting a specific type of target.
