Garrett and Minelab are the two brands detectorists argue about most, and the argument usually comes down to one machine each: Garrett’s AT Max and Minelab’s Equinox 900. We put the two flagships — and the philosophies behind them — side by side.
This matchup by the numbers
- 1964 vs 1985 — Garrett has manufactured in Garland, Texas since Charles and Eleanor Garrett founded the company in 1964; Minelab has built in Adelaide, Australia since 1985, per each company’s published history.
- ~$240 — the price gap between the Garrett AT Max (~$759) and the Minelab Equinox 900 ($999), our brand-roundup guides’ current verified pricing for each flagship.
- 10 ft vs 16 ft — submersion depth: the AT Max is rated to 10 ft, the Equinox 900 to 5 m (16 ft, IP68), per each manufacturer’s spec sheet.
- 1 vs 5+ frequencies — the AT Max runs single-frequency VLF at 13.6 kHz; the Equinox 900’s Multi-IQ engine transmits multiple simultaneous frequencies (5-40 kHz range) by default.
- 3 years — the warranty length both Garrett and Minelab publish on their consumer detectors, the one spec where the two brands are identical.
Head to head: the flagships
| Spec | Garrett AT Max | Minelab Equinox 900 |
|---|---|---|
| Price | ~$759 | $999 |
| Technology | 13.6 kHz single-frequency VLF | Multi-IQ simultaneous multi-frequency |
| Submersion | 10 ft (whole machine) | 16 ft / 5 m (IP68) |
| Wireless audio | Z-Lynk | Included wireless headphones |
| Best ground type | Freshwater, relics, trashy parks | All-round, especially wet salt sand |
| Country built | USA (Garland, TX) | Australia (Adelaide) |
| Warranty | 3 years | 3 years |
Where the Garrett AT Max wins
Garrett AT Max
- Roughly $240 cheaper than the Equinox 900 for a machine built on two decades of All-Terrain refinement.
- Single-frequency VLF is simpler to learn and tune than a multi-frequency menu.
- US manufacturing and US-based service through Garrett's Texas facility.
- A huge installed base of relic and coin hunters means deep community knowledge for troubleshooting.
Between digs, it’s worth stocking up on field reference material — Kindle Unlimited’s catalog includes coin ID guides and treasure-hunting how-tos that pair well with either brand’s finds; you can try Kindle Unlimited free before your next hunt.
For hobbyists who hunt inland parks, fields, and old home sites rather than salt beaches, the AT Max’s single-frequency engine is proven, not outdated — our full Garrett lineup guide breaks down every model below it, from the ACE 300 through the Vortex.
Where the Minelab Equinox 900 wins
Minelab Equinox 900
- Simultaneous Multi-IQ reads a wider mix of target depths and metal types in a single pass.
- Handles wet salt sand — the condition that blinds most single-frequency machines — far better than the AT Max.
- Ships with a bonus 6-inch coil alongside the standard 11-inch, useful in trashy or tight spots.
- Rated to 16 ft submersion, 6 ft deeper than the AT Max.
The Equinox 900 anchors our Minelab lineup guide, and its multi-frequency advantage is exactly why it’s the top pick in our best beach metal detector guide — salt sand is the one condition where the technology gap between the brands shows up most.
Worth considering instead
If neither flagship fits the budget or the ground you hunt, these alternatives from our overall rankings are worth a look:
| Alternative | Why instead | Technology | Price |
|---|---|---|---|
| Garrett Vortex VX9 | Garrett's own multi-frequency answer to the Equinox | Simultaneous multi-frequency | ~$600 |
| Minelab Equinox 700 | Same Multi-IQ platform, smaller coil kit, less money | Multi-IQ multi-frequency | $699 |
| Garrett AT Pro | Proven AT platform for less, if the Max's extras don't matter | 15 kHz single-frequency | ~$563 |
| Nokta Legend 2 | Third-brand challenger, wireless firmware updates | Multi-frequency, 5+ modes | ~$999 |
The decision framework
- Inland parks, fields, and relics on a budget → Garrett AT Max. Proven single-frequency performance for $240 less, backed by decades of US manufacturing.
- Beach hunting or maximum versatility → Minelab Equinox 900. Multi-IQ handles salt sand and small gold that single-frequency machines miss.
- Want Garrett but need multi-frequency → Garrett Vortex VX9. Garrett’s own answer to the Equinox, at roughly $150 less.
- Undecided on brand loyalty at all → compare both against a third option in our Nokta lineup guide, which undercuts both on price at similar waterproofing.
The bottom line
There’s no wrong brand here, only a wrong fit. The Garrett AT Max is the better buy for inland, budget-conscious relic and coin hunters who want a proven single-frequency machine backed by decades of US manufacturing. The Minelab Equinox 900 earns its ~$240 premium with Multi-IQ multi-frequency technology that reads more ground types — especially wet salt sand — in a single pass. Both carry identical 3-year warranties, so the decision comes down to where you actually hunt, not which company backs the machine longer.
