Nokta Impact Pro Pack Metal Detector – Multi-Frequency, 12 Search Modes

What Is the Nokta Impact Pro Pack?

The Nokta Impact Pro Pack metal detector is a three-frequency induction balance VLF that runs at 5 kHz, 14 kHz, or 20 kHz one frequency at a time, selectable from the menu. The Pro Pack stacks the IM19 7.5" x 4" elliptical DD coil on top of the standard IM28 11" x 7" DD coil, plus a carrying bag, an extra lower shaft (so the 7.5" x 4" coil can stay mounted for quick swaps), AC and car chargers, four AA rechargeable batteries, wired headphones, coil covers, a stand, a USB cable, and the user manual. Both coils are waterproof DD designs. The control box is water-resistant and is not submersible. The Impact weighs 4.26 lb (1.93 kg) on a balanced shaft, with the coil cables routed inside the rod assembly to keep snag points off the build.

Three Selectable Frequencies: 5 / 14 / 20 kHz

The Impact transmits and receives on one frequency at a time and switches between three on the same hardware. Drop to 5 kHz for chasing deep silver, large coppers, and high-conductive relics in low-mineral ground; lower frequency spreads target ID range on the high-conductive end and reaches further on coin-sized targets. Run 14 kHz as the all-around setting for parks, schoolyards, and general coin work; this is the default and the setting most hunters live in. Switch to 20 kHz for low-conductors like small gold rings, fine chains, and sub-gram nuggets in mild ground. The Impact uses induction balance, not simultaneous multi-frequency, so the detector broadcasts and reads on a single selected frequency rather than running all three at once. The on-the-fly frequency change is what separates the Nokta Impact metal detector from fixed-frequency VLF rigs at this tier.

12 Search Modes Grouped by Hunt Type

The Impact ships with 12 factory search modes. Four are discrimination modes with multi-tone audio: DI2 (2-tone), DI3 (3-tone), DI4 (4-tone), and DI99 (99-tone). Four are all-metal modes that pair a threshold hum with optional discrimination: GEN and GEN(D) for motion all-metal, STA and STA(D) for non-motion (with the (D) variants adding discrimination audio over the all-metal hum). DEEP mode is the call when ground is clean and you want the last inch on a faint target. COG (Conductive Ground) extends the ground-balance range from 0 to 90 (versus 20 to 90 in other modes) to handle salt sand and conductive soil. VLX1 and VLX2 are specialized modes tuned for low-mineral soils. For park coin shooting and trashy permissions, start in DI3 or DI4 and adjust tone break to separate clad and silver from foil and pull tabs. For relic ground, the GEN(D) and STA(D) all-metal modes give you a threshold all-metal hum with discrimination audio on top, useful when deep iron and non-ferrous targets sit close together. iSAT (Intelligent Self Adjusting Threshold) holds threshold stable through mineralization and hot rocks.

Ground Conditions: Where the Impact Performs and Where It Has Limits

The Impact handles moderate mineralization once you run Ground Grab, Manual, or Tracking ground balance. In red clay, volcanic soil, and Midwest farm fields, the detector stays stable when gain is kept in check and the mode matches the site. The Impact earns its reputation on iron-infested permissions; DI4 with tone break adjustment and DI99 with iron volume tuned in give you fine target separation in iron clusters. Swing the 7.5" x 4" IM19 coil slow and low at colonial home sites, Civil War camps, or old fairgrounds and you can recover coins and small relics from the gaps between iron that the larger 11" x 7" IM28 reads as one tone. The Impact handles dry sand and wet sand reasonably well using COG mode for salt-conductive soil adjustment. Surf hunting is outside the design envelope because the control box is not submersible. For full submersion or aggressive saltwater work, a fully waterproof SMF detector or PI machine is the better tool.

Who Should Buy the Nokta Impact Pro Pack?

The Nokta Impact Pro Pack metal detector fits relic hunters and intermediate-to-advanced coin shooters who want selectable single-frequency control on iron-trashy sites without paying for a flagship SMF rig. Hunters who switch sites often, working parks one weekend, colonial home sites the next, and beach hunts in between, get real value from the two-coil package, three frequency selections, and the 12-mode bench in one machine. Beach detectorists working dry sand and the wet wash zone benefit from COG mode for salt-conductive ground and the 20 kHz setting on thin chains. The Impact's discrimination engine rewards detectorists who already understand tone break, iron volume, and how to read DI99 audio in iron. New detectorists are better served starting with a simpler turn-on-and-go detector and stepping up after the Impact's menu set makes sense in the field. The Impact is not the right pick for buyers who need full submersion for surf hunting; for that work, a fully waterproof SMF or PI machine is the right call.
