Introducing the Garrett Gold Master 24K Metal Detector

XGB Ground Balance System

Auto tracking system allows the GM24k to be used in a wide variety of ground conditions with more stable operation and less ground noise. This all-new XGB ground balance system can handle mineralized ground unlike other VLF prospecting machines. For advanced users, TracLock and Ground Grab are just a tap of button away. You can even assign a ground balance offset in both TracLock or XGB modes. To help prospectors that prefer drywashing, sluicing, or panning, the Goldmaster® 24k features a Ground Scan mode that can show you where valuable paystreaks are in streambeds and washes.

With 10 levels of adjustable sensitivity, adjustable audio volume with two levels of Boost, adjustable discrimination, vSAT, adjustable threshold, non-motion pinpoint, and a Tone ID mode, the Garrett Goldmaster® 24k might just be the most advanced VLF gold nugget metal detector on the market. But don’t let that scare you if this is your first prospecting machine – this is a turn-on-and-go machine, with advanced features you can grow into without sacrificing performance.
