About the Garrett AT Pro

The Garrett AT Pro combines adjustable ground balance, Garrett's Pro audio with proportional response, a 0 to 99 numeric target ID and a housing Garrett rates submersible to 10 feet (3 meters). Garrett lists its operating frequency as 15 kHz.

We like the AT Pro because it pairs a waterproof build with Pro audio, which gives useful information about target characteristics, and it is a proven general-purpose detector for coins, jewelry and relics. We would choose it for waterproof coin, jewelry and relic hunting with informative audio.

Garrett AT Pro search modes and key settings

• Standard and Pro audio: six search modes, three Standard modes (Zero, Coins and Custom) with simpler, consistent target responses, and the same three patterns in Pro mode with proportional audio and tone roll audio. Pro audio presents more information through changes in signal strength and sound, and in our experience understanding the audio is more useful than relying on the target ID alone.
• Iron discrimination and Iron Audio: iron discrimination adjusts from 0 to 40 (the Coins mode preset is 35), notch discrimination is adjustable, and Iron Audio works in the discrimination modes.
• Ground balance: Fast Track automatic ground balance plus manual adjustment.
• Sensitivity, frequency adjust and pinpoint: eight sensitivity settings, four slightly different frequencies (F1 to F4), and electronic pinpointing in a non-motion all metal mode.
• Target ID: a 0 to 99 numeric scale with a 20-segment graphic scale above it.

Water and beach hunting with the Garrett AT Pro

Garrett rates the AT Pro submersible to 10 feet (3 meters) in fresh and salt water, and its manual says that exceeding that depth voids the warranty. The MS-2 headphones are a different matter: Garrett's manual says the provided headphones are for dry use only, and for underwater audio Garrett makes its own waterproof headphones (Garrett part 2202100). Freshwater shorelines and shallow water are where we recommend the AT Pro in the water, alongside parks, older properties and fields on land. See our waterproof metal detectors.

Where the Garrett AT Pro works well, and where it does not

Coin, jewelry and relic hunting suit the AT Pro, for intermediate detectorists who search parks, older properties, fields, freshwater shorelines and shallow water. See our relic and treasure metal detectors. For coin hunting, our best metal detectors for coins guide compares the options. For dedicated natural-gold prospecting, the Garrett AT Gold is more specialized, running at 18 kHz with a smaller 5 x 8 inch coil.

Garrett AT Pro coil, batteries and build

The AT Pro comes with the 8.5 x 11 inch PROformance Double-D searchcoil, and smaller compatible Garrett coils are available. Our coil guide explains what size and shape change. Garrett lists the AT Pro at 3.03 lbs (1.4 kg) with a stem adjusting from 43 to 56 inches (1.09 to 1.4 m). Four AA batteries run it for 20 to 40 hours depending on battery type and quality; NiMH rechargeables work, and Garrett advises removing the batteries for storage longer than 30 days.

Garrett AT Pro or AT Max

The Garrett AT Max runs at 13.6 kHz and adds built-in Z-Lynk wireless audio, a backlit display, a true All Metal mode, ground balance with 175 points of resolution and an automatic Ground Balance Window. For someone who wants wireless headphones and those additional ground handling features, we would recommend the AT Max.

Getting started with the Garrett AT Pro

Searching a freshwater swimming area for lost jewelry, we use Pro mode in Zero, keep discrimination conservative and listen carefully to changes in the target response. The settings worth learning first are Pro audio, ground balance, Iron Audio and discrimination. The common mistake is using too much discrimination and rejecting some gold jewelry by accident.

Garrett AT Pro specifications

Garrett covers the AT Pro with a 3-year warranty, as it now does for its detectors, pinpointers and searchcoils.
