Field Use

Alluvial Creek and River Beds

Creek beds shift mineral composition across meters, with clay, gravel, and bedrock often sitting side by side in a single run. Easy-Trak adapts without manual input, letting you keep swinging through transitions that require constant rebalancing on fixed-balance machines. The 5″ GM05 coil fits into bedrock cracks and narrow crevices where coarser placer gold collects. Our post on detecting in mineralized soil covers ground handling strategy in more depth.

• Mode: Gold (iron reject)
• Sensitivity: Auto or Auto+
• Ground Balance: Easy-Trak (automatic)
• Volume: 5–6 near running water

Arid and Mineralized Goldfields

Red earth, caliche, and volcanic ground push heavy ground noise into most VLF detectors, forcing operators to drop sensitivity or accept false signals. The 24-bit processor on this machine filters ground interference without cutting depth, letting you run Auto+ in mineralization that forces lower-spec detectors back to manual control. Gold mode’s iron rejection handles scattered ferrous debris common in old diggings without silencing the machine.

• Mode: Gold (iron reject)
• Sensitivity: Auto+ on quiet patches; step to Manual 7–8 if the machine chatters
• Ground Balance: Easy-Trak (automatic)
• Volume: 4–5 in high-mineralization areas

Old Dredge Piles and Tailing Fields

Tailings stack iron junk directly over gold-bearing material. Gold mode’s iron rejection reduces nuisance signals from nails, bolts, and ferrous debris without shutting down sensitivity to conductive targets at the same depth. Deep All Metal is available for a quick check of a quiet corner where you want maximum sensitivity and are willing to dig more signals.

• Mode: Gold (iron reject) for iron-heavy areas; Deep All Metal for clean spots
• Sensitivity: Manual 6–7
• Ground Balance: Easy-Trak
• Volume: 5–6

45 kHz VLF and 24-Bit Signal Processing

VLF detection at 45 kHz produces stronger electromagnetic responses from small, low-conductivity targets like fine gold flake. At 45 kHz, this detector sits well above the 18–19 kHz range typical of general gold-capable VLF machines, producing audible responses on sub-gram targets that register only as faint threshold variations on lower-frequency detectors.

The 24-bit signal processor handles higher-frequency data without introducing proportional noise. It tightens ground filtering while preserving target signal integrity, which is why this machine runs Auto+ in moderate mineralization rather than forcing you to back off sensitivity to stay stable. The Gold Chance Indicator translates that processed signal into a real-time visual read, shifting right for conductive metals, left for ferrous targets and hot rocks.
