Garrett Axiom Pulse Induction Metal Detector with Dual Coils and MS-3 Wireless Headphones

The Garrett Axiom is the pulse induction machine we recommend for prospectors who have outgrown a VLF gold detector and want depth on small gold without losing their minds in mineralized ground. This standard package ships with a 13" x 11" DD coil, an 11" x 7" mono coil, and Garrett's MS-3 Z-Lynk wireless headphones. Backed by a 3-year manufacturer warranty and shipped fast from our Michigan warehouse, it sits at the top of the Garrett Axiom metal detector lineup as the most capable PI Garrett currently builds. Prospectors weighing the jump from single-frequency VLF machines to pulse induction can cross-shop the Axiom against other flagship detector models built for extreme ground conditions.

Dual-Channel Ground Balance for Mineralized Goldfields and Saltwater Beaches

Mineralized Goldfields

Arizona caliche, Nevada hot ground, and the iron-stained washes of the Mother Lode can shut down a VLF inside ten minutes. The Axiom's Terra-Scan dual-channel ground balance reads two independent magnetic signatures at once, so as we move from a conductive layer into magnetic basalt, the threshold stays stable instead of chirping over every transition. Fine timing pulls the smallest pickers we have any business chasing, while Normal timing reaches deeper nuggets without giving up too much on small gold. Our team runs Mode: Fine for sub-gram work, Normal for deeper hunts, Sensitivity at 5 to 6 and drops to 4 in extreme ground, Ground Balance on Ground Grab then Slow Tracking, and Speed set to Medium. Black sand and alkaline desert dirt that would force a VLF into constant ground rebalancing or false signals get neutralized without manual intervention every few feet.

• Best for: Prospectors working Arizona, Nevada, and California goldfields where VLF machines chatter over hot rocks and magnetite.
• Less ideal for: Urban tot-lot coin shooting where a VLF's discrimination and target ID offer faster decision-making on clad versus trash.

Saltwater Beaches and Wet Sand

Salt and black sand are exactly where most VLFs surrender. Salt mode on the Axiom tunes pulse delays to ignore the conductive saltwater signal while still hitting lost rings and gold chains in wet sand and the swash zone. The mono coil delivers more raw depth on a clean signal and is our pick for open beach. The control box is rainproof for surf-side work, and the coils are fully waterproof for wading. We run Mode: Salt, Sensitivity at 5, Ground Balance on Auto dual-channel, and Speed set to Medium. Detectorists hunting water resistant environments gain the ability to work the surf line without the conductive salt masking targets.

Old Relic Sites with Iron in the Ground

PI detectors have a reputation for digging every nail in a homestead. The Axiom changes that math when paired with the 13" x 11" DD coil and Iron Check turned on. Iron targets get an audible flag, which lets our team skip the obvious junk and dig the non-ferrous tones that matter. For a deeper walk-through of mode setup and ground tracking, we keep the Garrett Axiom setup guide bookmarked. We run Mode: Normal with Iron Check on when using the DD coil, Sensitivity at 5 to 6, Ground Balance on Ground Grab then Medium Tracking, and Speed set to Medium to Fast in iron-dense ground. This feature closes a real gap PI machines have long had against trashy relic ground.

Four Pulse Timings, 16-Hour Battery Life, and 4.2 lb Swing Weight

• Stable performance in heavy mineralization: Terra-Scan dual-channel ground balance keeps the threshold smooth across black sand, alkaline desert dirt, and hot rocks that would force a VLF into constant ground rebalancing or false signals.
• Four pulse timings tuned to the gold you are chasing: Fine, Normal, Large, and Salt modes let our team match the machine to sub-gram pickers, deeper nuggets, or saltwater beach work without changing detectors.
• Iron Check on the DD coil: Pair the 13" x 11" DD with Iron Check and the Axiom audibly flags ferrous targets, which closes a real gap PI machines have long had against trashy relic ground.
• Sixteen hours of run time on the internal lithium-ion battery: Roughly twice what some PI prospecting detectors deliver, and the included AA booster pack adds another six hours when we are deep in the backcountry.
• 4.2 lb swing weight with the 11" mono coil: The Axiom is the lightest PI in its class, which matters on the eight-hour days this style of detecting demands. With the 13" DD coil the weight climbs to 4.7 lbs, still manageable for full-day swings.

Compare within the family

The primary difference between these two packages is the headphone type and the coil pairing. The MS-3 wireless headphones eliminate the cable between the control box and your ears, which matters when you are threading through brush or working tight quarters. The DD coil in this package is the larger 13" x 11" footprint, which gives you Iron Check capability and broader ground coverage, while the mono is the smaller 11" x 7" for sub-gram sensitivity. The sibling package flips that pairing, shipping the larger mono and smaller DD. Both packages deliver the same four timing modes, the same Terra-Scan dual-channel ground balance, and the same 16-hour battery life. Prospectors who want wireless audio and the larger DD coil for Iron Check work pick this package; those who prefer wired headphones and the larger mono coil for raw depth pick the sibling.

Ultra Pulse Technology and Terra-Scan Explained

Pulse induction sends a current into the ground, shuts it off, and listens for the decaying eddy currents bouncing back from metal. Garrett's Ultra Pulse implementation runs at a 1500 Hz adjustable pulse rate and gives the Axiom four selectable timings, which is what really sets a modern PI apart from older single-timing prospecting machines. Fine timing keeps the receiver gate open earlier to hear small, low-conductivity gold. Large timing waits longer and reaches further into the ground for bigger, deeper targets. Salt timing gates out the saltwater conductor entirely. Terra-Scan handles the ground side of the equation by reading two independent ground balance channels at once, so heavily mineralized soil and conductive hot rocks both get neutralized without forcing a manual rebalance every few feet. This is the mechanism that lets the Axiom run stable in Arizona caliche, Nevada hot ground, and black sand beaches where VLF machines chatter constantly.

The dual-channel architecture is why prospectors moving from single-frequency VLF detectors to the Axiom report immediate threshold stability gains in mineralized ground. Where a VLF reads one ground signal and tries to null it out, the Axiom reads two independent magnetic signatures and adjusts for both simultaneously. When you cross from a conductive layer into magnetic basalt mid-swing, the threshold stays smooth instead of chirping over the transition. Ground Grab initializes the balance, then Slow, Medium, or Fast Tracking keeps it current as you move across varying soil. For prospectors working the Mother Lode, the Sonoran, or the Bradshaw Mountains, this is the feature that turns previously unworkable ground into huntable territory.

Carbon-Fiber Shaft, Backlit Display, and Z-Lynk Wireless Audio

The Axiom rides on a carbon-fiber S-shaft that collapses to 25 inches for travel and extends to 61.5 inches for taller swings. Total weight is 4.2 lbs with the 11" mono coil and 4.7 lbs with the 13" DD, with the balance point set so the swing stays neutral over long days. The backlit LCD shows mode plus sensitivity alongside dual ground balance numbers without burying anything in submenus. A USB-C port handles charging and firmware updates from a laptop. Audio is where Garrett gave the Axiom flexibility most prospectors actually want. PWM and VCO audio types are both available depending on how you read targets, and an integrated Z-Lynk wireless link drives the included MS-3 headphones with no transmitter dongle in the way. A 1/4" jack accepts standard wired headphones, and the high-volume speaker is loud enough for open desert work without ear protection.

The Z-Lynk radio also pairs with the Garrett Pro-Pointer AT Z-Lynk pinpointer, which routes the pinpointer's signal through the same MS-3 headphones during recovery. This means you can leave the headphones on through the entire target recovery process without swapping between detector audio and pinpointer audio. The control panel layout is straightforward: power, mode selector, sensitivity, threshold, ground balance, volume, and Iron Check toggle are all top-level controls with no submenu diving. The backlight is bright enough for pre-dawn starts and post-sunset finishes, and the dual ground balance indicator gives you real-time feedback on how the machine is reading magnetic and conductive ground signatures independently.

Coil Options and Accessory Compatibility

The standard package ships with the 13" x 11" DD and the 11" x 7" mono. The 11" mono is our default for sub-gram pickers and tight, brushy ground where a smaller footprint helps. The 13" DD is the coil we reach for when Iron Check matters or when we are covering open ground and want broader sweep width. Garrett offers additional coil sizes for the Axiom: a 16" x 14" DD, a 16" x 14" mono, a 13" x 11" mono, and an 11" x 7" DD are all available as separate purchases. The larger 16" coils are for maximum ground coverage and depth on bigger nuggets; the smaller 11" x 7" DD is for detectorists who want Iron Check capability in a compact coil for tight spaces. All Axiom coils are waterproof and ship with coil covers. The DD coils support Iron Check, the mono coils do not but deliver slightly more raw depth on clean signals.

The MS-3 Z-Lynk wireless headphones included in this package are the step-up audio option in the Axiom line. They eliminate the cable between the control box and your ears, which matters when you are threading through manzanita or working steep hillsides where a cable snags on brush. The sibling package in the Axiom lineup ships with wired MS-2 headphones instead, which some prospectors prefer for the direct connection and the slightly lower package price. Both headphone options deliver the same audio fidelity; the choice is cable versus wireless convenience. For detectorists comparing the Axiom against other machines in the pulse induction metal detectors category, the Z-Lynk wireless system and the dual-coil standard package are differentiators at this price point.
