{"product":{"id":8289339801884,"title":"Garrett AT MAX Metal Detector with Z-Lynk Wireless Technology","body_html":"\u003cp\u003eThe Garrett AT MAX is a 13.6 kHz single-frequency VLF built for detectorists who need wireless audio, deep target response, and full submersion capability in one package. It delivers noticeably more depth on deep silver and brass than entry-level VLFs, true wireless audio through the included MS-3 Z-Lynk headphones with no dongle or latency, and quieter behavior in mineralized soil thanks to a 175-point ground balance. Fully submersible to 10 feet, it runs on four AA batteries and ships with the 8.5 by 11 inch DD PROformance coil already mounted.

The 13.6 kHz frequency on the AT MAX strikes a useful balance between coin sensitivity and tolerance for trash, and Pro Audio gives us proportional volume and pitch shifts that make a faint silver dime feel different from a junk signal at depth. Detectorists looking out for the \u003ca href=\"https:\/\/seriousdetecting.com\/pages\/best-metal-detectors-for-coins\"\u003ebest metal detectors for coins\u003c\/a\u003e will find that this platform pulls deep copper and silver out of historic dirt with distinct clarity. We start in Custom Mode so we can keep low-conductor information in the audio while we work iron-heavy zones, dial Iron Discrimination between 25 and 30, and set Sensitivity to 6 or 7 depending on EMI.\u003c\/p\u003e\n\n\u003ch3\u003eSaltwater Beach and Surf\u003c\/h3\u003e\n\u003cp\u003eSubmersible to 10 feet, the AT MAX handles wet salt sand and shallow surf without false-locking the way a non-saltwater VLF does. We use Zero Mode to keep every signal audible, dial Iron Discrimination low so light gold rings are not silenced, and let the auto ground tracking ride the wet-sand transition. Sensitivity runs at 5 to 6 in saltwater, stepping up to 7 in damp sand where mineralization drops.\u003c\/p\u003e\n\n\u003ch3\u003eRelic Fields and Civil War Sites\u003c\/h3\u003e\n\u003cp\u003eTrue All-Metal Mode is where this detector quietly stretches its lead over the AT Pro: an unfiltered, deepest-possible audio response that surfaces brass buttons, lead, and small iron fragments most discriminators bury. We run a tight, slow sweep, listen for repeatable mid-tones, and let the 0 to 99 Target ID give a second opinion before digging. All-Metal Iron Audio lets us hear discriminated iron while staying in the deepest mode, so we stop chasing flat steel without losing depth.\u003c\/p\u003e\n\n\u003ch2\u003eZ-Lynk Wireless Audio and Backlit Display for Long Field Sessions\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eWireless audio without a dongle: Z-Lynk pairs the detector to the included MS-3 headphones automatically, no cord pulls at our shoulder, no aftermarket adapter, no latency we can hear in the field.\u003c\/li\u003e\n\u003cli\u003eA backlit screen we can actually read at dusk: the Target ID stays visible during late-evening park hunts and pre-dawn beach walks when other VLF screens go dark.\u003c\/li\u003e\n\u003cli\u003eCleaner separation in trashy ground: with 44 iron discrimination segments and All-Metal Iron Audio, our team can hear iron grunts under good targets and skip bottle caps before we cut a plug.\u003c\/li\u003e\n\u003cli\u003eQuieter behavior in mineralization: the Automated Ground Balance Window and 175-point manual range tame hot dirt and saltwater that would chatter a basic VLF.\u003c\/li\u003e\n\u003cli\u003eReal depth on deep coins: enhanced transmit power and eight Sensitivity steps let us push the AT MAX harder in clean ground, where we routinely reach targets that whispered or vanished on an AT Pro.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cfigure\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0760\/1464\/9628\/files\/atmax-screenSQ.jpg?v=1774644348\" alt=\"Garrett AT MAX metal detector control box with digital display, mode buttons, sensitivity controls, and Z-Lynk wireless technology\"\u003e\u003c\/figure\u003e\n\n\u003ch2\u003eCompare within the family\u003c\/h2\u003e\n\u003cp\u003eDetectorists cross-shopping the \u003ca href=\"https:\/\/seriousdetecting.com\/collections\/garrett-at-series\"\u003eGarrett AT series - all-terrain waterproof detectors\u003c\/a\u003e often weigh the AT MAX against the AT Pro and AT Gold.
