Garrett Goldmaster 24K 48 kHz Gold Metal Detector
The Garrett Goldmaster 24K is a high-frequency VLF gold detector built to find small nuggets and fine flakes in mineralized ground. It runs at 48 kHz, near the top of the range for gold machines at this price, which gives it the sensitivity to hear sub-gram gold that lower-frequency detectors walk over. The detector ships with the waterproof 6 inch by 10 inch DD searchcoil, Garrett ClearSound headphones and a rechargeable battery system.
At the center of the Goldmaster 24K is the XGB ground balance system. Its auto-tracking keeps the detector stable across changing mineralization, hot rocks and black sand, so you spend less time chasing ground noise and more time on targets. Advanced users can lock the balance with TracLock, take a fresh reading with Ground-Sync or run Ground Scan to follow paystreaks in washes and streambeds.
A large backlit display shows your settings along with a target graph and a 0 to 99 target ID, so you can read ferrous, gold and high-conductor ranges at a glance. Two audio modes let you hunt by a 2-tone beep or a VCO zip that rises with signal strength, and adjustable sensitivity, threshold, discrimination, iron cancel and frequency shift let you tune the machine to the dirt.
This is a focused gold machine for prospectors working washes, desert placers and old goldfields. It weighs 3.4 lbs (1.5 kg), adjusts from 45 inches to 54 inches and runs on 8 AA batteries. GeoWork Supply ships the Goldmaster 24K complete with the owner's manual and quick start guide linked below.

Features
48 kHz Frequency for Small Gold
The Goldmaster 24K operates at 48 kHz, near the top of the range for gold detectors at this price. That high frequency makes it sensitive to small nuggets and fine flakes that lower-frequency machines walk over.

XGB Auto-Tracking Ground Balance
The XGB ground balance system tracks changing mineralization on its own for stable, quiet operation in hot ground. Lock it with TracLock, refresh it with Ground-Sync or run Ground Scan to follow paystreaks in washes and streambeds.

Backlit Display and 0 to 99 Target ID
A large backlit LCD keeps your settings, target graph and target ID readable in low light. Target ID numbers run 0 to 99 and sort signals into ferrous, gold and high-conductor ranges.

Two Audio Modes, Beep or Zip
Choose a 2-tone beep mode to separate target types or the VCO zip mode where pitch and volume climb with signal strength. Adjustable threshold and a non-motion pinpoint help you center a target before you dig.
Waterproof 6 by 10 Inch DD Coil
The included 6 inch by 10 inch DD searchcoil is waterproof and submersible, so you can work wet ground, creek edges and shallow water. The detector housing is rainproof for hunting in the weather.

Iron and Hot Rock Control
Adjustable iron cancel and a frequency shift help you cut hot rocks, iron trash and electromagnetic interference. Ten levels of sensitivity and adjustable discrimination let you match the machine to the dirt.

Light Enough to Swing All Day
At 3.4 lbs (1.5 kg) and adjustable from 45 inches to 54 inches, the Goldmaster 24K is easy to swing on long days. It runs on 8 AA batteries, with a rechargeable set and charger in the box.
