Quick Answer: The Garrett AT Pro (~$549.99) is still one of the most field-proven all-terrain detectors money can buy in 2026 — a 15 kHz VLF engine, 40 levels of iron discrimination through Pro Mode’s proportional audio, and a fully submersible 10 ft (3 m) build. First released in 2010, it remains popular enough that an independent 2026 review from DetectHistory still scores it 8.8/10. It gives up the newer AT Max’s backlit display and built-in Z-Lynk wireless audio, but none of the underlying detection ability, and it undercuts the AT Max by roughly $200.
The AT Pro shows up across nearly every all-terrain and relic-hunting guide on this site — our Garrett lineup guide calls it “the best value all-terrain” Garrett makes, and our relic hunting guide ranks it the best all-around relic detector, period. This review checks whether that reputation still holds up fifteen years after launch, against the newer AT Max above it and the cheaper ACE 400 below it.

15 kHz and 40 levels of iron discrimination: why relic hunters still choose it
The AT Pro’s 15 kHz VLF engine is a full generation older than the multi-frequency Vortex line Garrett now sells, but frequency alone never told the whole story here. What made the AT Pro the American relic-hunting standard is Pro Mode’s proportional audio combined with 40 levels of iron discrimination, per Garrett’s own published spec — instead of a flat accept/reject beep, faint iron tones come through at low volume rather than being silenced entirely, which matters because many valuable relics (belt buckles, bayonets, buttons) read as ferrous. Our ground balance guide covers the manual technique the AT Pro uses to cancel mineralized-soil interference, one of the most capable manual implementations in Garrett’s lineup even against newer machines.
Pro Mode audio and the headphones it actually ships with
The AT Pro comes in the box with Garrett’s wired MS-2 headphones, not the wireless Z-Lynk system bundled with the newer AT Max — a distinction that trips up buyers who assume every current Garrett ships wireless. You can retrofit Z-Lynk wireless audio onto an AT Pro with a separate transmitter adapter, covered in our headphones guide, but it is an add-on purchase, not a built-in feature. For hunters who do not mind a cord, the wired MS-2s add zero latency and one less battery to manage in the field.
AT Pro vs AT Max: is the extra ~$200 worth it?
The AT Max shares the AT Pro’s 10 ft whole-machine submersion and All-Terrain fundamentals, but adds built-in Z-Lynk wireless, a backlit display for early-morning and evening hunts, and an Automated Ground Balance Window for soil that shifts across a single site — plus a slightly lower 13.6 kHz frequency Garrett tuned for more stable depth in mineralized ground. None of that changes the underlying detection category: the AT Pro is not a lesser detector, it’s a less refined version of the same machine. Budget-conscious hunters lose little going with the AT Pro; hunters who want the polish should spend the extra $200.
AT Pro vs ACE 400: when the step-up pays off
Garrett publishes no waterproof rating at all for the ACE 400’s control box — dealers describe only the search coil as submersible — while the AT Pro is rated to 3 m (10 ft) whole-machine, a genuine published Garrett figure. The ACE 400 ($357.99) is lighter at 2.9 lb and delivers most of the same dry-land coin-and-relic result for $192 less, using its simpler Iron Audio toggle instead of 40-level discrimination. The AT Pro earns its price the moment creeks, rivers, or old iron-littered home sites are part of the plan — ground where the ACE 400 is simply the wrong tool.
Who should buy the Garrett AT Pro
- Relic and coin hunters working creeks, rivers, and old home sites — the 10 ft submersion and 40-level iron discrimination are exactly what that ground demands.
- Buyers who want proven over new — 15+ years of settings guides, forum knowledge, and documented finds sit behind every AT Pro sold.
- Budget-conscious all-terrain hunters — it delivers the AT Max’s core detection ability for roughly $200 less.
- Not beach hunters chasing wet salt sand — single-frequency machines lose depth there; see our beach detector guide for multi-frequency picks instead.
- Verify the seller before buying. Garrett’s warranty runs through authorized dealers only — check the “Sold by” line on any Amazon listing before checkout.
The bottom line
The Garrett AT Pro at $549.99 remains the machine every mid-range all-terrain detector still gets judged against — a 15 kHz engine, 40 levels of iron discrimination, and a genuinely submersible 10 ft build, all fifteen years after its 2010 launch. Step up to the AT Max if the backlight and built-in wireless are worth ~$200 to you, or step down to the ACE 400 if your hunting stays dry. Curious how it stacks up against Nokta’s flagship instead?
