What Is the Garrett AT Pro Metal Detector?
The Garrett AT Pro metal detector is the long-running All-Terrain VLF detector that sits in the middle of Garrett's AT family, between the AT Gold and the flagship AT Max. The AT Pro is the model that taught a generation of hunters Pro Mode Audio: proportional audio response on every target paired with Tone Roll Audio to help separate good signals from bad. The AT Pro runs at 15 kHz on a single-frequency VLF platform, is fully submersible to 10 ft (3 m), and ships in a coin/jewelry/relic-ready configuration with the 8.5" x 11" PROformance DD coil and the MS-2 wired headphones. Garrett manufactures the AT Pro at its Garland, Texas facility, the Garland, Texas operation Garrett has run since the company was founded in 1964.
Garrett AT Pro Key Features in the Field
15 kHz Operating Frequency for Coins, Relics, and Jewelry
The AT Pro runs at 15 kHz on a single-frequency VLF platform. That puts it slightly above the AT Max (13.6 kHz) and gives the AT Pro a small edge on mid- to higher-conductivity gold rings, thin silver chains, and small relic targets, while still holding depth on copper and silver coins. For hunters who work pastures, parks, and old home sites in the eastern half of the country, 15 kHz is a balanced single-frequency choice.
Pro Mode Audio: Proportional Response Plus Tone Roll
Pro Mode Audio is the differentiator that gives the AT Pro its name. Pro Mode delivers proportional audio response, so the volume of a target's tone tracks the strength of its signal: deep, faint, or edge-of-coil targets sound softer, near-surface or large targets ring louder. Tone Roll Audio adds a secondary tonal cue that helps detectorists separate good targets from iron false signals. Three Pro Mode search programs give experienced operators full Pro Mode Audio behavior; three Standard audio modes are also onboard for new detectorists who prefer a simple "beep on a good signal" workflow.
High-Resolution Iron Discrimination, 40 Levels
The AT Pro offers 40 levels of iron discrimination, finer resolution than the typical 0 to 19 ID system on entry-level detectors. The finer scale lets coin shooters notch out specific iron ranges in trashy parks and old home sites while still hearing aluminum, brass, and gold ranges. Iron Audio (the option to audibly identify discriminated iron) is available within the AT Pro's discrimination modes. All-Metal Iron Audio is an AT Max-only feature, so the AT Pro does not extend Iron Audio into its non-motion All-Metal pinpoint workflow.
Digital Target ID (0 to 99) with Notch Discrimination
Each target reads out on a 0 to 99 Digital Target ID scale across the top of the LCD. Notch Discrimination lets you accept or reject specific ID bins so you can skip known trash ranges without losing nearby good targets. Adjustable Threshold sets the constant background hum, so you can hear faint and deep targets without overdriving the audio.
Fast Track Ground Balance
The AT Pro uses Fast Track Ground Balance: Garrett's automatic ground balance procedure that lets the operator quickly null out mineralized soil response in the field. Fast Track is fast to set, easy to re-balance when soil conditions change across a site, and is the same automatic ground balance routine that runs on the AT Max (the AT Max adds the Automated Ground Balance Window option for severely mineralized soils, which the AT Pro does not have).
Electronic Pinpointing (Non-Motion All-Metal)
The Electronic Pinpointing button puts the AT Pro into a non-motion All-Metal mode so you can hover the coil over a target, narrow the response, and mark the exact location before you cut a plug. The on-screen meter shows depth and signal strength during pinpointing.
Submersible to 10 ft (3 m)
The AT Pro is fully submersible to 10 ft (3 m) - both the control box and the included 8.5" x 11" PROformance DD coil. Hunt wet sand, the wash zone on a freshwater beach, creek crossings, and rainy permissions without breaking down the rig. The AT Pro uses the AT submersible 2-position headphone connector for the included MS-2 wired headphones; a sealed wired headphone option is available for true underwater audio.
Tough Build with Camlocks and Push-Pin Locks
Camlocks plus an adjustable stem with push-pin locks keep the rig rigid under repeated swings. The textured rubber grip is non-absorbent for wet hunts, and the 4 AA battery system (batteries included) keeps replacement power available on site without needing a charger.

Garrett AT Pro vs. AT Max: Which All-Terrain VLF Fits Your Hunt?
The AT Pro and AT Max share the same All-Terrain VLF chassis, the same 8.5" x 11" PROformance DD coil, and the same 10-foot submersion rating. The differences sit in operating frequency, ground balance system, audio behavior, and what ships in the box.

Stay with the AT Pro if you prefer the slightly higher 15 kHz frequency for jewelry and small relic work, a wired audio chain for underwater hunts, and the proven Pro Mode Audio that defined the AT line. Step up to the AT Max if you want the Automated Ground Balance Window for severely mineralized soils, Iron Audio in All-Metal mode, a backlit LCD for low-light hunts, and Z-Lynk wireless audio standard in the box.
Where the Garrett AT Pro Performs Best
Coin shooters working iron-trashy parks and old town greens get the 40-level High-Res Iron Discrimination plus Pro Mode Audio for finer separation between iron false signals and good targets. Relic hunters working colonial home sites, farm fields, and battlefield permissions get a 15 kHz single-frequency VLF that responds well to the small brass and pewter targets that turn up on those sites, plus the depth on copper coins and large iron. Jewelry detectorists working manicured grass and tot lots get a frequency that handles thin gold and small silver chains, plus electronic pinpointing for quick recovery. Beach and shallow-water hunters use the 10 ft (3 m) submersion rating to work wet sand, the wash zone on freshwater beaches, and creek crossings; for full salt-water beach hunting on a heavily mineralized salt beach, a pulse induction or simultaneous multi-frequency platform will edge out a 15 kHz VLF in pure salt-handling performance.
Recommended Accessories for the Garrett AT Pro
Pair the AT Pro with the Garrett Pro-Pointer AT for plug-side recovery; the Pro-Pointer AT carries the same 10-foot waterproof rating and shares Garrett's one-button interface. Garrett AT-compatible coil options include the 4.5" Super Sniper for tight trashy patches, the 5" x 8" DD for trashy sites with tighter target separation, the 6.5" PROformance concentric for general-purpose work, and the 9" x 12" PROformance concentric for open-ground depth coverage. Browse the wider aftermarket search coil selection. For underwater audio, the Garrett Submersible Headphones with 2-position AT connector are the in-brand option. Round out the recovery kit from the digging tool collection.
