Garrett AT Pro Waterproof Metal Detector
The Garrett AT Pro is an all terrain VLF detector that brings professional audio features to a machine built for everyday coin, relic and jewelry hunting. It runs at a 15 kHz operating frequency, and the housing, stem and 8.5 inch by 11 inch DD searchcoil are submersible to 10 feet (3 m), so it moves from a dry field to wet sand or shallow fresh water without a second machine. GeoWork Supply ships it with the Garrett MS-2 headphones.
The AT Pro gives you six search modes split into three Standard and three Professional settings, so a new user can start simple and grow into Pro Mode Audio. Pro Mode Audio adds proportional response and Tone Roll, which lets you hear the size, shape and depth of a target the way you would in all metal. A 0 to 99 digital Target ID and 40 levels of iron discrimination help you separate good targets from trash.
Recovery speed is quick, so the AT Pro picks good targets out of trashy ground, and Iron Audio lets you hear discriminated iron to skip bottle caps and flat washers. Ground balance is automatic and manually adjustable, the housing is built for dusty, humid and wet sites, and the detector will ground balance to saltwater for beach work. A coin depth indicator and battery condition readout round out the display.
The AT Pro weighs 3.03 lbs (1.37 kg), adjusts from 43 inches to 56 inches and runs on 4 AA batteries that are included. It suits coin, jewelry, relic, cache and ghost town hunting, competition events, prospecting and beach or fresh water hunting. GeoWork Supply ships it complete and ready to assemble, with the owner's manual linked below.

Features
Six Search Modes and a Clear Display
Three Standard and three Professional modes let you start simple and move up to Pro Audio when you are ready. A 0 to 99 Target ID, a target legend and a coin depth scale read out on the display so you know what is under the coil.

Waterproof to 10 Feet, All Terrain
The control housing, stem and DD coil submerge to 10 feet (3 m), and the AT Pro will ground balance to saltwater for beach work. The weatherproof build handles dusty, humid and wet sites with ease.

Pro Mode Audio and Iron Audio
Pro Mode Audio uses proportional response and Tone Roll, so you hear the size, shape and depth of a target instead of a flat beep. Iron Audio lets you hear discriminated iron and skip flat trash like bottle caps and washers.

Complete and Ready to Hunt
The AT Pro arrives with the 8.5 inch by 11 inch DD submersible searchcoil, the Garrett MS-2 headphones and the batteries installed, so it is ready to assemble and search out of the box.

Where the AT Pro Fits in the AT Line
The AT Pro sits between the AT Gold and AT Max, with a 15 kHz frequency that balances coin, relic and jewelry hunting. The chart shows how the three all terrain models compare on frequency and features.

Fast Recovery and 40 Level Iron Discrimination
Quick recovery speed lets the AT Pro pick good targets out of trashy ground, and 40 levels of iron discrimination give you fine control to sort iron from keepers. It carries light at 3.03 lbs for long days afield.
