Why Buy Your AT Pro Metal Detector From Kellyco?

Stu Detecting in Antigua

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 detectorists.

David and Stu Auerbach from Kellyco with Brent Weaver from Garrett
Sept.17,2010 (L to R). David and Stu Auerbach from Kellyco Metal Detectors with Brent Weaver Director of Product Development for Garrett Metal Detectors getting "hands on advice" from Brent who directed the AT Pro Project to a very successful product introduction.

2011 - 25 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. 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.

AT Pro Modes

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.

AT Pro Target Response

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.

AT Pro Target Info

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 search coil 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.

AT Pro Water

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 unequaled ability to detect good targets amongst iron trash.

AT Pro Digital ID

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.

AT Pro Digital ID Face

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.

Superb Detector

Review by Jim on April 04, 2016

Forget people who tell you this is TOO COMPLICATED for beginners. It is one of the easier machines to work with beginner OR pro. It has just the right size coil for the majority of detecting and has the ability to use different coils to tailor it to a specific search criteria. Couple that with an extremely short learning curve and you have a sure bet when it comes to finding the 'good stuff'. Add an additional bonus of buying from KELLYCO and you simply can't lose. Excellent machine, Excellent Company.

Review by Richard M on March 29, 2016

This unit is as good as it gets! It takes little time to adjust and off you go detecting. It has excellent depth even in our highly mineralized soil. The gauge gives you all the information needed to find your target. I like all types of treasure hunting and it does it all. If there was anything that I would change on the detector it would be that it was just a little lighter and that's not to say it's heavy because it's not. I also own a machine from down under and this unit is much much easier to learn and use! Garrett has really done their homework. Outstanding job Garrett!

AT Pro

Review by Jeffery D on March 25, 2016

With the AT Pro I have found a little bit of everything. Love it.

Great Mid-Priced Detector

Review by Gene on March 21, 2016

I've used the AT Pro for about 3 years now. I have had very good success hunting the tot lots and parks. The AT Pro really excels in trashy areas with the 5x8" coil. I went over areas "hunted out" using the small coil. I was very impressed with the coins I picked up. I did lose some depth, but I solved that problem by purchasing a NEL 9.5x5.5" sharpshooter coil. I retained the ability to separate trash from good targets as well as gaining the depth. Last coin I found was a dime at 8". I like being able to hunt during light rain or snow if I am on a coin streak. This machine really turned out to be a real winner.


Review by Ellie on February 12, 2016

Best buy ever!! I started with the Garrett Ace 250 and worked my way up. Couldn't ask for a better machine! Within the first month I am finding gold!! Yeah buddy!! AT Pro is an awesome machine!!
