Goldmaster 24k Metal Detector


The Garrett Goldmaster® 24k is a high-frequency induction-balance gold nugget detector. The GM24k features a 54% increase in coil voltage over the prior White’s GMT model, resulting in increased sensitivity to small nuggets.

Experienced prospectors know more sensitivity is not the only answer to increasing the odds of success. A machine’s ability to track and cancel the ground is often the biggest challenge faced in the search for gold. That’s why the Goldmaster® 24k features a special ground tracking system called “XGB” (Xtreme Ground Balance). It works with multiple ground points to ensure stable operation. The GM24k also features Iron/Hot-Rock cancellation in both audio modes, which expands the ground range even more for quiet operation in the most challenging ground.
