Nokta Impact PRO Metal Detector Overview
The Nokta Impact PRO is a VLF metal detector that transmits on one of three frequencies at a time, 5 kHz, 14 kHz or 20 kHz, selected from the menu. It has 12 search modes, Automatic, Manual and Tracking ground balance, gain from 01 to 99, a 00 to 99 Target ID, iron volume, tone break, notch filter, frequency shift, pinpoint, vibration, an LED flashlight and a backlit custom LCD. Both coils in the Pro Pack are waterproof DD designs: the IM28 11 x 7 inch and the IM19 7.5 x 4 inch. Nokta's manual warns not to put the system box in water and to keep it dry, so only the coil goes under. The Impact PRO weighs 1.8 kg (4 lb) with the coil and batteries, adjusts from 107 to 143 cm (42 to 56 inch), and runs on 4 x AA batteries for about 9 to 17 hours depending on the frequency, with the shortest run time at 5 kHz. Nokta covers the Impact PRO for 2 years.
Impact PRO vs. Triple Score Pro Pack: Which Should You Buy?
The Nokta Triple Score Pro Pack runs simultaneous multi-frequency (SMF) plus single 4, 15 and 20 kHz frequencies, is IP68 waterproof to 5 m (16 ft) as a whole detector, weighs 1.2 kg (2.6 lb) with the coil and has four search modes (Park, Field, Beach, Relic) with a 3-year warranty. The Impact PRO runs one frequency at a time, but gives you 12 search modes: two static (non-motion) modes, two all metal modes and eight discrimination modes, including COG for conductive ground.
We recommend the Impact PRO for relic hunters and experienced coin hunters on land who want to choose a frequency for the site and work iron with a large set of modes. We recommend the Triple Score Pro Pack if you want to take the whole detector into the water, hunt wet salt sand often, or want fewer menus.
Nokta Impact PRO, Best For:
- Relic hunters on iron-heavy homesites and old camps who want iron volume, tone break and DI99 audio
- Detectorists who switch between 5 kHz for larger and high-conductive targets and 20 kHz for small jewelry
- Hunters who want static, non-motion modes for pinpointing and sizing up a target
- Two-coil buyers who want the IM19 small coil in the box for tight spots
Nokta Triple Score Pro Pack, Best For:
- Beach, surf and creek hunting where the whole detector goes under water
- Hunters who prefer SMF with fewer menus and four preset search modes
- Detectorists who want a lighter detector and Bluetooth headphones in the box
Three Frequencies and 12 Search Modes
Nokta's manual gives each frequency a job. 5 kHz is for large ferrous and non-ferrous objects, high-conductive coins, and medium or small targets in ground that is not mineralized and has no iron trash. 14 kHz is the general-use frequency for small coins and coins of various sizes in medium to highly mineralized ground. 20 kHz is for small coins, thin large coins, gold coins, rings, small jewelry and small targets in iron trash.
The 12 modes fall into three groups. The static modes, STA and STA (D), work without coil motion. The all metal modes, GEN and GEN (D), give a threshold hum, with the (D) versions adding discrimination audio. The eight discrimination modes are DI2, DI3, DI4, DI99, COG, DEEP, VLX1 and VLX2. DEEP is the deepest mode, recommended for relic hunting with a slower swing; it runs a little noisier and discriminates less than the other modes, so it works better on clean sites than trashy ones. VLX1 (3 tones) and the deeper VLX2 (4 tones) are lower noise modes for changing ground and all levels of mineralization. COG is built for conductive ground such as salty wet beach sand and alkali soil, and ground balances across 0 to 90 where the other discrimination modes auto balance in the 20 to 90 range. iSAT (Intelligent Self Adjusting Threshold) sets how fast the threshold recovers in the all metal modes, cuts false signals from ground noise and hot rocks in the discrimination modes, and counters threshold drift in the static modes. For park coins we recommend starting in DI3 or DI4 and setting tone break to separate iron from the targets you want.
Where the Impact PRO Works Best and Its Limits
The Nokta Impact PRO metal detector is a land machine first: farm fields, old homesites, parks and dry beach sand. On iron-heavy sites we recommend swinging the IM19 7.5 x 4 inch coil slow and low, so targets between iron read on their own instead of merging with the iron. On a salt water beach, use COG mode in the wet sand and the other modes on dry sand; Nokta's manual advises keeping the coil either fully in the water or fully out of it to avoid false signals, and says signals from holes dug in wet sand are normal. Because the system box is not waterproof, wading and surf hunting are outside what the Impact PRO is built for. The large mode set takes time to learn, so we recommend a simpler detector for someone in their first season.
Coils and Accessories That Fit the Nokta Impact PRO
The Pro Pack box holds the system box, the IM28 11 x 7 inch DD coil with cover, the IM19 7.5 x 4 inch DD coil with cover, headphones, an extra lower shaft so the second coil can stay mounted, a USB data cable, a USB charger with 4 x AA rechargeable batteries, the user manual, a stand, protective covers and a carrying bag.
Nokta lists three waterproof DD coils for the Impact PRO: the IM19 7.5 x 4 inch, the IM28 11 x 7 inch and the larger IM45 15 x 17.5 inch. The Impact collection also holds the IM13 5 inch and IM24 9.5 x 5 inch waterproof DD coils, a CORS Point 5 inch DD coil, and covers for the IM13, IM24, IM28 and IM45 coil sizes. For power and comfort there is the Nokta Impact USB battery charger, the armrest and strap, a 23 inch middle shaft and coil mounting hardware. The Impact PRO works with Nokta's optional 2.4 GHz wireless headphones, and this collection also holds the EZ Wander wireless module and Koss wired headphones with a 1/4 inch jack. The digital Impact manual is here too.
