Garrett AT Pro All-Terrain Waterproof Metal Detector

The Garrett AT Pro is the all-terrain VLF that lets us walk from a dry park lawn into a creek bed without swapping machines. Running 15 kHz with proportional Pro Audio and a fully waterproof control housing rated to 10 feet, it delivers the depth, target separation, and submersible build that single-frequency land machines cannot match. It remains one of the most respected upgrade detectors in the Garrett AT series - all-terrain waterproof detectors, and our team recommends it to detectorists who want a do-everything VLF without stepping into multi-frequency pricing.

• Garrett AT Pro control housing with S-shaped stem
• 8.5" x 11" PROformance DD submersible search coil

Proportional Pro Audio and 40-Level Iron Discrimination for Trashy Sites

Old Homesites and Iron-Infested Relic Sites

Cellar holes, foundations, and old farms are buried in iron, and the trick is keeping the good non-ferrous targets without drowning in nails. The AT Pro's 40-level iron discrimination plus proportional Pro Audio lets us hear the size and depth of a target through tone, so we can ignore short, stuttering iron grunts and dig the clean, repeating mid-tones. We run PRO mode with a custom discrimination pattern, iron discrimination set between 25 and 35, sensitivity at 6 to 7, and manual ground balance before each hunt.

Park and Schoolyard Coin Shooting

Modern parks are full of pull tabs, foil, and bottle caps sitting between us and the silver. The PRO mode plus the Coins discrimination pattern reads conductivity tightly enough to cherry-pick the coin signals while letting tabs and caps return as muted, broken tones. We set iron discrimination to 35, sensitivity to 7 or 8, and let the auto ground balance handle the mineralization. Detectorists hunting for the best metal detectors for coins will find that the AT Pro’s narrow target profiling lets you pull old wheat pennies out of modern trash with ease.

Creeks, Rivers, and Shallow Submerged Hunts

The fully waterproof control housing rated to 10 feet is what separates the AT Pro from any land-only very low frequency (VLF) metal detectors in the same price bracket. We can wade into a creek bend, chase signals across river bottoms, and submerge the housing without sealing tape or aftermarket covers. We run PRO mode with zero discrimination, iron discrimination at 20 to 25, sensitivity between 6 and 7, and auto ground balance in fresh water or manual at the salt line.

Saltwater Beaches and Surf

Wet salt sand chatters most single-frequency machines into uselessness. The AT Pro is not a multi-frequency saltwater specialist, but with a careful manual ground balance and a slight sensitivity reduction, it runs stably enough to grid the tide line and wade chest deep into the wash for ring drops. We switch to STD mode with zero discrimination, iron discrimination at 25, sensitivity between 4 and 6, and re-balance manually as the surf line moves.

Fast Recovery and Tight Target Separation with DD Coil

• Submersible to 10 feet means we can wade into surf, hunt fresh-water creeks, and chase signals into the wash without babying the control box.
• Proportional Pro Audio reads target depth and edges through tone strength, so faint and deep targets stop sounding identical to shallow ones: we hear the difference between a deep silver coin and a shallow nail without digging both.
• 40-level iron discrimination gives us fine resolution to keep iffy signals while still rejecting bottle caps and rusted bottle tops at iron-heavy sites.
• Fast recovery and tight target separation with the 8.5" x 11" DD coil pull good targets out of trash that an entry-level concentric coil walks past.
• Manual or automatic ground balance stabilizes the AT Pro in the mineralized red dirt and wet salt sand that make beginner machines chatter and false.
