Technical Specifications
In-Depth Field Performance
Detection Depth & Coverage
In field testing, the Nokta Simplex Ultra demonstrates consistent target acquisition across various soil types. The Ultra 11" x 7" DD provides excellent ground coverage while maintaining sensitivity to smaller targets. With a maximum detection depth of 11-13" (coin), it performs admirably for beginners and beach hunting. Recovery speed between targets is fast enough for trashy sites, making it suitable for recreational hunting.
Target ID & Discrimination
Target identification on the Nokta Simplex Ultra uses 25 segments to differentiate between valuable finds and junk. The 6 search modes provide flexibility for different hunting scenarios. Audio feedback is clear and responsive, helping you make quick dig decisions. The Bluetooth 5.0 aptX + wired delivers clear tones even in noisy outdoor environments.
Technology & Ground Handling
Nokta equipped the Nokta Simplex Ultra with SMF + single (4, 8, 14, 20, 24 kHz) technology, which is optimized for detecting a wide range of targets from gold jewelry to silver coins. The Auto + Manual system gives experienced users full control over mineralization compensation. The submersible coil allows hunting in wet grass, shallow streams, and rainy conditions.
Build Quality & Ergonomics
Weighing 2.87 lbs (1.3 kg), the Nokta Simplex Ultra is lightweight enough for extended hunting sessions without fatigue. The 44" to 53" adjustable accommodates users of different heights. Build quality is solid and designed for outdoor durability. 20 hours means less worry about power during full-day hunts.
Settings & Modes Guide
Choosing a Search Mode
The Nokta Simplex Ultra offers 6 search modes. For beach and wet-sand hunting or underwater and shallow-water recovery, start with the preset closest to that target type — it pre-loads discrimination and tone breaks tuned for it — then fine-tune discrimination and sensitivity from there as you learn the site.
Discrimination Setup
Discrimination on the Nokta Simplex Ultra runs on 25 segments. Notch narrowly rather than rejecting broad ranges of the scale — wide notches on a segmented display bury real targets that share a tone with trash.
Ground Balance
The Nokta Simplex Ultra's Auto + Manual ground balance gives you both options. Leave it on auto/tracking for normal parks and fields — it adjusts on the fly and needs no attention. Switch to manual in heavily mineralized soil, black sand beaches, or old homesites where auto-tracking can drift: pump the coil a few inches over clean ground until the threshold stops changing, lock it in, and re-check whenever the soil type changes.
Sensitivity & Mineralization
The Nokta Simplex Ultra runs at SMF + single (4, 8, 14, 20, 24 kHz). In average, low-mineralization soil, sensitivity can run near the maximum stable threshold for the deepest signal. In mineralized ground — red clay, black sand, or salt-contaminated soil — back sensitivity down until the false chatter settles, then re-check your ground balance.
Pros & Cons
- Multi-frequency at Simplex price
- Full waterproof to 16 ft
- Bluetooth aptX low latency

Things to Know Before You Buy
Heavier than original Simplex
Something worth weighing before you buy, based on real owner feedback.
More complex operation
Budget a few outings to get comfortable before judging the detector on its full potential.
Newer model, less tested
Fewer long-term owner reports exist compared to established models — factor that into your risk tolerance.

What Else You Need With the Nokta Simplex Ultra
A detector on its own finds targets it cannot recover. These are the tools experienced detectorists carry on every hunt — about $220.87 for the set, and none of them are optional once you have dug a few holes.
Garrett Pro-Pointer AT
The coil gets you inside a foot. A pinpointer gets you to the exact inch, which is the difference between a two-minute recovery and a ten-minute hole.

Garrett Edge Digger
You cannot recover a target without digging it. A serrated digger is the first thing every detectorist buys after the machine itself.

GADFISH Stainless Sand Scoop
On sand, a digger is useless — the hole collapses before you reach the target. A sifting scoop is the only practical recovery tool at the beach.

Garrett MS-2 Headphones
The faint targets are the deep ones. A speaker loses them to wind and traffic long before the coil does.

In optimal low-mineralized soil, the Nokta Simplex Ultra can detect a quarter-sized coin at 11-13" (coin). Larger objects like relics and caches can be detected at greater depths. In highly mineralized ground, expect 15-20% reduction in depth. Actual results depend on soil conditions, target size, and discrimination settings.

Start on the search mode closest to "beach" — the Nokta Simplex Ultra ships with 6 search modes, and the closest match pre-loads discrimination and tone breaks for that target type. Keep discrimination low at first so you don't skip real targets while you learn the site, and ground balance manually before you start swinging. Tighten discrimination and sensitivity once you know what the local trash sounds like.
The Nokta Simplex Ultra uses 25 segments for target ID. Start with little to no discrimination so you learn what iron, foil, and pull tabs sound like in your specific soil, then notch out only the confirmed junk tones — narrow notches beat wide ones, since wide rejection zones also bury real targets.
The standard Nokta Simplex Ultra package includes: the detector unit, Ultra 11" x 7" DD, coil cover, rechargeable battery pack, and user manual. Some retailers offer accessory bundles with additional coils, carrying bags, and digging tools.
