Nokta Impact Metal Detector
The Nokta Makro Impact is a selectable multi-frequency VLF detector that lets you switch between three operating frequencies (5, 14 and 20 kHz) to match the target and the ground. It is a feature-rich, highly adjustable machine favored by hobbyists who like to tinker - and valued for taking swappable AA batteries you can change in the field.
Pros
- Three selectable frequencies (5, 14, 20 kHz)
- Deep adjustability - full ground balance, iron audio, tone control
- Field-swappable AA batteries
- Capable, respected older machine
Cons
- Heavier than Nokta's current models at around 4.4 lbs
- Selectable, not simultaneous, multi-frequency
- Older generation - availability varies
Overview
The Impact comes from Nokta's Makro line and predates the brand's simultaneous multi-frequency era. Rather than running several frequencies at once like the newer Score and Legend families, it lets you select one of three frequencies - 5 kHz, 14 kHz or 20 kHz - so you can tune low for depth on large targets or high for small, high-conductivity finds. It is a VLF machine with deep menus and a lot of control for the enthusiast.
Key features
- Three selectable frequencies - 5, 14 and 20 kHz to suit different targets and soils.
- Three-mode ground balance - automatic, manual and tracking, so you can dial in difficult ground yourself.
- Iron Audio (Fe volume) - turn down or off the low iron tone to cut nuisance trash.
- Adjustable audio tone - set the pitch of target and threshold tones across a wide range for your own ears.
- Swappable AA batteries - a standout for many owners, who like being able to carry spares and change them anywhere.
At roughly 4.4 lbs it is heavier than Nokta's current lightweight models, a reflection of its older-generation hardware.
Who it is for
The Impact suits the hands-on hobbyist who enjoys adjusting settings and understanding what each one does, and anyone who specifically wants field-swappable batteries. One long-time owner summed up the appeal: the Impact is a very good detector, praised for the ability to change batteries as needed, even if it is less feature-packed than the latest flagships. If you want a modern simultaneous multi-frequency machine out of the box, Nokta's newer families are the better fit.
How it compares and related models
Compared with Nokta's current lineup, the Impact trades the newer simultaneous multi-frequency technology for selectable single frequencies and a more manual, tinker-friendly approach. It is older and heavier, but its depth, adjustability and removable batteries keep it in demand on the used market.

Buying note
Because the Impact is an older model, availability and price vary - it often turns up as a strong used buy. Confirm which coil and configuration a listing includes before you commit.

Frequently Asked Questions
How many frequencies does the Nokta Impact have?
Three selectable operating frequencies: 5 kHz, 14 kHz and 20 kHz. You choose one at a time to match the target and ground, rather than running them simultaneously.
Does the Nokta Impact use rechargeable or AA batteries?
It runs on standard AA batteries you can swap in the field - a feature many owners specifically value because they can carry spares.
Is the Impact still worth buying?
It remains a capable, highly adjustable VLF machine, especially on the used market. If you want current simultaneous multi-frequency technology, look at Nokta's newer families instead.
