Nokta Deephunter 3D PRO Metal Detector

Nokta Deephunter 3D PRO Overview

The Nokta Deephunter 3D PRO combines two VLF systems in one control unit and switches between them with one button. Mode 1, the visual system, is a non-motion deep treasure mode running at 12.5 kHz with the T44 44 x 36 cm (17.5 x 14 inch) DD coil or the larger T100 100 x 60 cm (39.5 x 23.5 inch) DD coil. Mode 2, the audio system, is a fast motion mode running at 17.5 kHz with the C32 32 x 26 cm (12.5 x 10 inch) DD coil or the larger C47 47 x 39 cm (18.5 x 15.4 inch) DD coil. Ground balance and sensitivity are manual in both modes. Both run on a 14.8 V 3300 mAh lithium polymer battery, rated about 4 hours in Mode 1 and about 24 hours in Mode 2, charged with the AC charger or the car charger. Nokta lists a weight of 1.4 kg (3 lb) in Mode 1 and 0.85 kg (1.9 lb) in Mode 2, a stem length of 85 to 135 cm (33.5 to 53 inch) and a 2-year warranty.

Deephunter 3D PRO vs. Jeohunter 3D Dual System and Invenio: Which Should You Buy?

All three are Nokta deep search systems with cavity detection. The Deephunter 3D PRO and the Nokta Jeohunter 3D Dual System both use T44 and T100 coils of the same sizes, a 3D display that sorts targets into metal groups, and depth in centimeters. The Deephunter adds Mode 2, a 17.5 kHz motion mode with its own C32 and C47 coils and about 24 hours of battery, for swinging a field for coins, jewelry and gold between deep scans. The Jeohunter adds the T21 small coil for walls, hillsides and tight spaces. The Nokta Invenio uses an IPTU positional sensor and a 7 inch screen to draw the target's shape, size and depth, with six search modes and a 00 to 99 Target ID.

We recommend the Deephunter 3D PRO when you want one system for deep cache and cavity scans and for ordinary motion hunting on the same trip. We recommend the Jeohunter 3D Dual System when tight spaces and walls matter, and the Invenio when you want a picture of the target's shape before you dig.

Nokta Deephunter 3D PRO, Best For:

• Deep cache searches with the T100 coil in Mode 1
• Cavity searches: caves, repositories, tunnels, shelters and tombs, including metals inside them
• Coins, jewelry and small gold in Mode 2, with three audio tones
• Mineralized ground such as beaches, wet sand and plowed soil, with Mode 2's ferrous settings

Nokta Jeohunter 3D Dual System, Best For:

• Cavity and deep searches with a depth readout for both metals and cavities
• Walls, hillsides and tight spaces with the T21 coil
• Detectorists who want three coils for three jobs in one system

Mode 1 and Mode 2 in the Field

Mode 1 is the slow, visual pass. Hold the coil still or swing it slowly while the color display builds a 3D image of the signal and shows the target's metal group (Gold, Precious, Non-precious or Steel), its depth in centimeters and a graphic shape. Mode 1 also detects cavities and underground structures such as caves, repositories, tunnels, shelters and tombs, and can identify metals inside them. Ferrous rejection lets it show precious metals only. We recommend the T44 for general Mode 1 work and the T100 for deep cache scans over open ground. Reading the 3D image well takes practice: we read signal strength, graph shape and metal group together rather than trusting any one of them, and we recommend scanning a few known targets at known depths with the T44 before you work a real site.

Mode 2 is the fast, audio pass. Swing the C32 or C47 at normal detecting speed and the Deephunter identifies targets by tone: a low tone for ferrous targets and two similar high tones for precious and gold targets. Mode 2 has ferrous settings for highly mineralized ground such as beaches, wet sand and plowed soil, and ferrous elimination to detect precious metals only. We recommend the C32 for fast work around individual targets and the C47 for more coverage, and we clear an area quickly in Mode 2, then switch to Mode 1 when a signal is worth a slower 3D look.

Where the Deephunter 3D PRO Works Best and Its Limits

The Nokta Deephunter 3D PRO metal detector is at home on old homesites, suspected cache sites and ground where cavities or underground structures matter, with Mode 2 covering ordinary coin, jewelry and gold hunting on the same site. Ground balance and sensitivity are manual, so expect to set them for each site before you start. Plan Mode 1 sessions around the battery: about 4 hours in Mode 1 against about 24 hours in Mode 2, so carry the car charger on long trips. Mode 1 is a deliberate, slow search, not a way to cover a large field quickly; use Mode 2 for that. Keep the digital Deephunter 3D manual on your phone for the settings and button combinations.

What's in the Box and Accessories

The Deephunter 3D PRO package holds the system box, shaft, T44 and T100 coils, a T100 coil carrying bag, the C47 and C32 coils with covers, a leather system box carrying bag, harness, connection cable, headphones, the T100 search coil control unit, AC and car chargers, the 14.8 V 3300 mAh lithium polymer battery, the user manual, mounting hardware and a carrying bag.

Our Deephunter 3D collection also carries Koss headphones with a 1/4 inch (6.3 mm) jack, the search coil mounting hardware that fits the Deephunter 3D and the Impact, and the digital manual, so you can read how the system works before you buy. Nokta also lists the Nokta DetectoBag 38L backpack for the Deephunter 3D. For a part you do not see here, such as a coil cover, shaft, charger or spare battery, call or email us.

Nokta Invenio vs. Invenio Pro vs. Jeohunter 3D Dual System vs. Deephunter 3D PRO Comparison

All four are Nokta VLF deep search systems with cavity detection and a 2-year warranty, and the Deephunter 3D PRO and the Jeohunter 3D Dual System both use T44 and T100 coils with a 3D display. The table compares them on how they show the target, the frequencies they run, the coils in the box and how they are powered.
