Nokta Simplex Ultra Review
Simplex Ultra is a light, fully waterproof 15 kHz detector with six modes, 99 IDs, Bluetooth and unusually deep adjustment for an entry platform. Its limit is architectural: it is not simultaneous multi-frequency for conductive wet salt.
Bottom line
A strong inland and freshwater value; compare SMF pricing before buying
Choose Simplex Ultra for parks, fields, relic sites and freshwater where 1.2 kg weight, 5 m waterproofing, adjustable recovery, 30 sensitivity levels and detailed tones matter. Choose a Score-series or X-Terra Elite SMF model when wet salt is a regular site. Ultra is the most configurable Simplex, not a lower-cost Legend.
Decision table
Nokta Simplex Ultra specifications that matter
| Decision factor | Documented position | Practical consequence |
|---|---|---|
| Frequency | 15 kHz single-frequency VLF | Determines how the machine approaches targets and changing ground. |
| Water protection | 5 m / 16 ft | Separate housing protection from wet-salt stability. |
| Best user | budget users wanting many controls | A poor match wastes features or creates avoidable limitations. |
| Strongest feature | carbon shaft, recovery-speed and tone adjustment | The primary reason to choose this model. |
| Main caveat | no simultaneous multi-frequency | The compromise to accept before ordering. |

Decision analysis
What actually changes the purchase
Nokta specifies 15 kHz operation, Field, Park, 4 Tone, 99 Tone, Beach and All Metal modes, a 01–99 ID scale and automatic/manual/tracking ground balance. Beach mode helps setup but does not turn single-frequency hardware into SMF.
Ultra adds Bluetooth, vibration, notch, frequency shift, bottle-cap rejection, adjustable recovery and 30 sensitivity levels in a 1.2 kg IP68 package rated to 5 m. These are substantive controls, though beginners should establish clean presets before changing filters.
The stock coil and package vary by region, so confirm coil size, wireless headphones and charger before purchase. Nokta’s online firmware-update support is valuable, but buy for documented current behavior rather than promised future features.
