Quick Answer: The Garrett AT Gold ($639.99 at Tractor Supply) is an 18 kHz VLF detector built for gold prospecting, with a true threshold-based All Metal mode and a whole-machine waterproof rating of 10 ft (3 m). It shares that same waterproof depth with the pricier AT Pro ($549.99-$680 range) — but unlike the AT Pro, Garrett’s own spec sheet flags the AT Gold’s higher frequency as too hot for wet salt sand or salt water. Buy this one for freshwater gold and relic hunting, not for the beach.
Verified October 24, 2026: Price cross-checked against Tractor Supply ($639.99) against a wider retailer spread of $698.84 (Red Carpet Optics) to $799.95 (MetalDetectingWorld’s listed retail price) and a $749.98 ProPointer AT bundle (Walmart) — the AT Gold’s price moves more with bundling than most detectors this site tracks. Specs confirmed across Kellyco’s AT Pro-vs-AT Gold comparison and GPS Central’s current product listing.
This site has referenced the Garrett AT Gold across 6 other articles — the best metal detector for gold guide, the gold-detection explainer, and state guides for California, Nevada, New Mexico, and Colorado — but it never had its own dedicated review. This one covers the real AT Gold vs AT Pro tradeoff, the saltwater limitation most buyers miss, and who should actually spend $639.99 on this instead of the Gold Monster 1000 or the AT Pro.

Garrett AT Gold
- 18 kHz VLF with a true threshold-based All Metal mode, tuned for small gold nuggets in mineralized ground.
- Whole control box submerges to 10 ft (3 m) for creek and river wading — same depth rating as the AT Pro.
- 3.03 lb (1.4 kg) with a 42"-51" adjustable shaft; 4 AA batteries included.
The saltwater limitation most buyers miss
The AT Gold’s whole-machine 10 ft (3 m) waterproof rating is identical to the Garrett AT Pro’s — which makes it easy to assume the two machines are interchangeable for any wet-ground hunting, including the beach. They aren’t. The AT Gold’s 18 kHz frequency is deliberately tuned hotter than the AT Pro’s 15 kHz to maximize sensitivity to small gold targets, and that same hot tuning makes it unstable to run on wet salt sand or in salt water — a limitation Kellyco’s own AT Pro-vs-AT Gold comparison confirms directly. The AT Pro’s lower frequency is the one Garrett built to handle salt water cleanly. If freshwater creeks, rivers, and dry mineralized ground are your target, the AT Gold’s extra sensitivity to gold is worth the tradeoff. If you want one detector that also works ocean beaches, the AT Pro is the better single machine.
AT Gold vs AT Pro: two different jobs, same waterproofing
| AT Gold | AT Pro | |
|---|---|---|
| Frequency | 18 kHz | 15 kHz |
| Price | $639.99 | $549.99 |
| All Metal mode | True threshold-based | Not threshold-based |
| Discrimination | 2 preset patterns | Adjustable notches, custom patterns |
| Salt water / wet salt sand | Not recommended | Rated for use |
| Whole-machine waterproofing | 10 ft (3 m) | 10 ft (3 m) |
| Best for | Freshwater gold, relics in mineralized ground | General relic/coin hunting, including beach/surf |
Despite costing roughly $90 more, the AT Gold gives up adjustable discrimination for a narrower, gold-focused feature set — the true All Metal mode and higher frequency are the entire point. As our best metal detector for gold guide already covers, the AT Gold is the value all-rounder in that category specifically because it still does double duty as a relic and coin machine on dry or freshwater ground, unlike a dedicated VLF gold machine such as the Fisher Gold Bug 2 that gives up general-purpose use entirely.
Who should buy the Garrett AT Gold
- Freshwater gold prospectors working creeks, rivers, and mineralized soil who want threshold-based All Metal sensitivity to small nuggets.
- Relic and coin hunters on mineralized ground who want a secondary use case beyond pure gold hunting, without paying flagship pulse-induction prices.
- Not beach or surf hunters — the 18 kHz frequency is not recommended for salt water or wet salt sand; see the AT Pro instead.
- Not casual first-time gold hunters on a tight budget — the Minelab Gold Monster 1000 ($899) automates ground balance further for a near-hands-off experience, at a higher price point.
The bottom line
The Garrett AT Gold earns its spot as the value all-rounder in gold detecting: an 18 kHz true All Metal mode built for small nuggets, a 10 ft (3 m) whole-machine waterproof rating for creek and river wading, at $639.99. The real caveat is the one most buyers miss — that same hot frequency that’s great for gold makes it the wrong choice for salt water or wet beach sand, where the lower-frequency AT Pro is the better single machine. If gold in freshwater or mineralized dry ground is the plan, the AT Gold delivers; if the beach is part of the plan too, step up to the AT Pro or see our best metal detector for gold guide for the full lineup.
