Garrett AT Pro Metal Detector

AT Pro is Garrett’s All-New, All-Terrain, All-Treasure, Deep-Seeking,
Professional Treasure Hunter’s Detector!

Why Buy Your AT Pro Metal Detector From Kellyco?

1986 - 29 Years ago Charles Garrett and Stu Auerbach President of
Kellyco went into the Caribbean on a treasure hunting expedition and to
also field test the very first AT (All Terrain) metal detector on land and in
the water. AT3 went on to become a favorite detector for thousands of

2011 - 26 years later Kellyco's Stu and David Auerbach were among the first to test and use the new AT Pro at the Garrett factory in September 2010. And, the AT Pro is now one of the most popular selling detectors for both land & water.

Thinking of buying a detector? Buy from a company that knows metal detectors best! We have been using metal detectors and treasure hunting since 1955 ! We know metal detectors! Buy from the experts.

Technology Adds up to More Treasure
Standard and Pro Audio Modes
In Standard binary audio mode, the AT Pro provides a full-strength beep regardless of a target’s amplitude. Many detectorists prefer this consistent binary (either on or off ) target response. For those who want to hear more target information—similar to what is experienced with a True All-Metal detector—the AT Pro also offers a proportional (Pro) audio mode.

Proportional audio response allows the user to hear subtle changes in a target’s response. This allows the user to better judge a target’s size, shape and depth and has the additional benefit of a much faster recovery time when detecting adjacent targets.

Notice the differences in binary audio versus proportional audio in the two target scenarios above. The detector with binary audio gives a solid, consistent beep for both the shallow and the deep coin. In contrast, the AT Pro’s proportional audio provides a stronger signal for the shallow coin and a softer signal for the deeper coin. The actual profile, or signature, of the target’s response is heard, thereby providing more information.

These two adjacent coins would produce one strong signal from a binary audio detector. With proportional audio, a rise and fall of audio response allows the user to interpret the multiple targets.
Tone Roll Audio™
This feature provides the user with more audible target information to help identify targets, particularly iron objects. Metal detectors with binary audio produce a single target sound based upon the target’s strongest signal. Tone Roll Audio provides a variance of target tones as the searchcoil approaches, passes above and departs from a target. These varying phases, or tones of audio, provide better overall target information.

For many detectors with binary audio, bottle caps, steel washers, etc. sound like good targets, producing a high tone response. This is because the bottle cap’s shape and flat surface resembles a coin which tricks the detector. With Garrett’s Tone Roll Audio, however, the bottle cap will produce a very distinctive response with multiple tones. As shown, the bottle cap will produce a distinctive Low-High- Low response as compared to the coin’s High-only response.

All-Terrain Versatility

The AT Pro is engineered with a waterproof housing and connectors to protect in dusty, muddy, wet and humid environments. The AT Pro can be immersed in water to a 10-foot depth (maximum) to search in and along shorelines, rivers, piers, docks or swimming holes.

NOTE: Waterproof headphones (optional item shown in photo to left) must be used if the headphones are immersed in water. Standard headphones provided with AT Pro can not be submerged.

High-Res Iron Discrimination™
Use the (+) or (-) IRON DISC touchpads to precisely set iron discrimination to one of 40 levels for an unequalled ability to detect good targets amongst iron trash.

The AT Pro's Digital Target ID system provides a specific target value to help identify buried targets more precisely. Targets are identified on the LCD screen by number, with items near 1 being the most ferrous. The most conductive targets (such as thick silver) register closer to 99.

The target ID indicates a silver coin at 8 inches depth. The AT Pro's Pinpoint touchpad shows precise location. The Digital Target ID number of 85 corresponds with the Upper Scale Target ID Cursor.

Iron Audio™

Scattered iron objects in the ground can mask good targets and even create “ghost signals” that appear to be a good target. Garrett’s selectable Iron Audio feature allows the user to hear discriminated iron (normally silenced) in order to know the whole picture and avoid being tricked into digging an undesired target.

Iron Audio also allows the user to adjust the mid-tone’s range to include all targets above the point of discrimination. The user is effectively adjusting the cut-off between Low-tone discriminated trash targets and mid-tone targets. This Garrett feature works in both Standard and Pro Modes on the AT Pro. (See illustrations to the right.)

Normal division of low, mid and high tones on AT Pro. Iron Audio is set to OFF.
With the iron discrimination set to 20, all targets below 20 are silent with the Iron Audio OFF.
With the Iron Audio feature ON, the targets below 20 are now heard as a low tone and the mid-tone is expanded down to 20.
