VLF Metal Detectors
VLF (Very Low Frequency) metal detectors are the most popular technology in the hobby — and for good reason. By transmitting a single, steady frequency and reading the phase shift returned by each buried object, a VLF machine delivers sharp discrimination and a numeric Target ID, so you can tell a gold ring from a rusty nail before you ever break ground. That precision, combined with high sensitivity to small and shallow finds, makes VLF the ideal choice for coins, relics, jewellery and fine gold across the goldfields and farmland of West, Central and North Africa.
At AO Gold Detectors we carry a deep VLF lineup from the names prospectors trust. Garrett's ACE family — the entry ACE 150, ACE 200i, ACE 250, ACE 400 and the flagship ACE 400i — covers first-time detectorists through serious coin and relic hunters, while the rugged AT Pro, AT Gold and AT Max add all-terrain, submersible bodies. For natural gold, the Garrett Goldmaster 24K runs a super-sensitive 48 kHz, the Minelab Gold Monster 1000 is fully automatic at 45 kHz, and the switchable Minelab Eureka Gold reaches every nugget size. The Minelab X-Terra Pro, classic GTI 2500 and American-made Teknetics T2 round out a collection that pairs proven sensitivity with everyday affordability.
Every unit is genuine, authorised stock backed by full manufacturer warranty, and our team supports you in Arabic, French and English over WhatsApp — before and long after the sale.

How to choose
- How VLF works: one coil transmits a fixed frequency while another reads the signal returned by buried metal — the phase shift drives accurate discrimination and a numeric Target ID so you dig good targets and skip the trash.
- Match the frequency to the target: lower frequencies (7–15 kHz, e.g. Garrett ACE 400i at 10 kHz, AT Pro at 15 kHz, Teknetics T2 at 13 kHz) favour coins and silver; high frequencies (45–48 kHz, e.g. Gold Monster 1000 and Goldmaster 24K) excel at small, fine gold.
- Choose VLF over PI or multi-frequency for excellent discrimination, light weight and value — ideal in moderate ground for coins, relics, jewellery and shallow gold. Step up to pulse induction or simultaneous multi-frequency only for deep nuggets in heavily mineralised or salty soil.
- Beginner or expert? The ACE 150, ACE 200i and ACE 250 are simple turn-on-and-go starters; the ACE 400/400i, X-Terra Pro and T2 add Target ID and refined discrimination; the Eureka Gold and Goldmaster 24K reward experienced prospectors.
- Ground and water: switchable-frequency models like the X-Terra Pro (5/8/10/15 kHz, waterproof to 5 m) and triple-frequency Eureka Gold adapt to changing soils, while submersible AT-series coils handle wet ground and the beach.
- Buy with confidence: every detector is genuine, authorised stock with full manufacturer warranty and trilingual WhatsApp support to help you choose the right coil and settings.
Frequently asked questions
What is a VLF metal detector and how does it work?
VLF stands for Very Low Frequency. The detector transmits a single steady frequency from its coil and measures the phase shift of the signal returned by buried metal. That measurement lets it discriminate between target types and display a numeric Target ID, so you can identify likely coins, jewellery, relics or gold — and reject iron trash — before digging.
When should I choose VLF instead of a PI or multi-frequency detector?
Choose VLF for excellent discrimination, light weight and great value when hunting coins, relics, jewellery and shallow or fine gold in moderate ground. Pulse induction (PI) ignores discrimination but punches deeper in heavily mineralised or salty soil, and simultaneous multi-frequency shines on wet beaches — so pick those only when your ground or target depth demands it. For most everyday detecting across African farmland and goldfields, a VLF machine is the most versatile and affordable choice.
Can VLF detectors find gold?
Yes. High-frequency VLF detectors are extremely sensitive to small, fine gold — the Minelab Gold Monster 1000 runs at 45 kHz, the Garrett Goldmaster 24K at 48 kHz, and the Minelab Eureka Gold offers switchable 6.4/20/60 kHz frequencies for nuggets of every size. Mid-frequency all-rounders like the Garrett AT Gold and AT Pro also handle gold jewellery and small nuggets well. For very deep nuggets in harsh mineralised ground, a pulse-induction detector reaches further.
Which VLF detector is best for a beginner?
For first-time detectorists, the Garrett ACE 150, ACE 200i and ACE 250 are simple, affordable and turn-on-and-go. If you want a little more, the ACE 400i adds a numeric Target ID and Iron Audio, while the Minelab Gold Monster 1000 is fully automatic — set up in seconds and start finding gold. We will help you pick the right model for your budget and ground over WhatsApp.
Are your VLF detectors genuine and under warranty?
Yes. AO Gold Detectors is an authorised dealer, and every VLF detector — Garrett, Minelab and Teknetics alike — is genuine stock sourced through official channels and backed by the full manufacturer warranty. Our team provides support in Arabic, French and English on WhatsApp, before and long after your purchase.
How much does a VLF metal detector cost?
VLF detectors span entry-level to mid-range, so the price depends on the model. Affordable starters like the Garrett ACE series are the easiest way in, while more capable machines such as the Garrett AT series, Minelab Gold Monster and Teknetics T2 cost more for their extra sensitivity and discrimination. Each model's price is shown on its own page (USD shown by default, with the AED price binding). There's no online checkout, so message us on WhatsApp for the current price and the best fit for your budget; every detector is genuine and comes with a manufacturer warranty.
