Garrett PI detector for gold detecting — verified specs.
The Garrett Axiom is a flagship-tier PI metal detector from Garrett, aimed at gold detecting. Standout: Ultra-Pulse PI technology with Terra-Scan dual-channel ground balance.
The Garrett Axiom is a flagship-tier PI metal detector from Garrett, aimed at gold detecting. Weighing 4.2 lbs / 1.9 kg with 11" mono coil, it sits on the lighter end of its class. Below: every spec verified against the manufacturer's own pages, with sources.
Spec note: The garrett.com Axiom product page (https://garrett.com/garrett-axiom-with-ms-3-headphones/?add-to-cart=2487) failed to load on a network error, so frequencies and waterproofing could not be verified on an official page and are left null. The official Garrett Axiom user manual (© 2022 Garrett Electronics, Inc., PN 0000000.A.0722) states 'Pulse Rate 1500 Hz (adjustable)' and 'Water/Weather Resistance: Waterproof coil/stem; Rainproof control box' — re-verify on garrett.com before publishing. Weight 4.2 lbs / 1.9 kg with 11" mono coil (4.7 lbs / 2.1 kg with 13" mono) confirmed on garrett.com.

The Garrett Axiom sits in Garrett's lineup alongside Garrett ACE 400, Garrett ACE Apex, Garrett AT Max, Garrett AT Pro. It uses Pulse induction (PI) — firing powerful magnetic pulses and measuring how fast the field decays. PI ignores salt and heavy mineralization and goes very deep — but discriminates poorly, so you dig more trash. The choice for goldfields and extreme beach depth. Compare it against its intended competition in our guides to the best gold prospecting detectors, and see how Garrett's range stacks up on the Garrett brand page.
The Garrett Axiom is best for gold detecting. Key strengths: ultra-pulse pi technology with terra-scan dual-channel ground balance.
The manufacturer has not published the operating frequency on its official pages, so we list it as not published rather than guessing.
No waterproof rating is published on the manufacturer's official pages. Treat it as not submersible unless the manufacturer states otherwise.

The Garrett Axiom is a strong pick for gold detecting, but no machine is universal. Check the waterproof line before any water use, confirm the weight against your stamina, and remember that ground conditions affect real-world performance more than any spec number.
