The Garrett AT Max instruction manual is the factory owner's manual for the AT Max, offered here as a free digital download. It is the file to grab if you picked up a used AT Max with no paperwork, left the printed booklet at home, or want the settings reference on your phone while you are standing over a signal you cannot call.
Who Needs This Manual
New Garrett AT Max detectors ship with a printed owner's manual in the box, so if yours arrived sealed you already have this. The digital edition earns its place in three situations: a secondhand machine that came without documentation, a booklet that has been soaked or lost, and field use, where a PDF on a phone beats paper in a wet jacket pocket. If you own a different machine, you want a different file. Our digital manual collection lists a separate download for each Garrett model, including the AT Pro, the AT Gold and the ACE line.

The Z-Lynk Wireless Operation and Iron Audio sections are the two worth reading twice. Z-Lynk is what separates the AT Max from the rest of the AT series, and the pairing routine is short enough that most owners never look it up until the headphones drop the link halfway through a hunt. Iron Audio is the setting that makes a bottle cap or a bent nail announce itself before you cut a plug, and the manual explains how it behaves differently in each of the four modes. For the machine itself rather than the paperwork, the Garrett AT MAX metal detector page covers how it is set up for coin, relic and shallow water hunting.
Languages and How the Download Works
Choose English, Spanish or French before adding the manual to the cart. Once the order is complete the download link appears on the confirmation page, in your confirmation email, and in your account, so you can save the PDF to a phone, tablet or laptop and keep it with you in the field. There is no charge and no shipping step.
