When you're prospecting dry washes, hillsides, and old mining claims where the soil runs hot with iron mineralization, the Fisher Gold Bug Pro delivers stable 19kHz single-frequency performance built for small gold. Hunters working Arizona caliche, Nevada desert ground, and California Mother Lode country use this detector to pull sub-gram nuggets other machines miss. The 5-inch DD coil ships with the unit, and at 2.5 pounds total weight, you can swing all day without shoulder fatigue.
What's included
- 5-inch DD search coil
- Batteries
- Two-year manufacturer warranty
Where the Gold Bug Pro Excels
Gold-Bearing Country
The 19kHz operating frequency targets small gold in the sub-gram range that lower-frequency machines walk past. We've hunted bedrock outcrops and dry wash concentrations where hot rocks and iron trash dominate the ground signal, and the computerized Ground Grab function locks the detector to the mineralization in seconds. The V-Break variable breakpoint tone discrimination system lets you notch out iron falsing while keeping audio response on gold targets, a real advantage when you're working old dredge piles or tailings.
Highly Mineralized Soil
Continuous ground condition readouts show you the ground phase value and Fe3O4 graphic in real time, so you know when you've moved from mild soil into hot ground and can re-balance on the fly. The All Metal mode runs a continuous threshold tone with VCO audio that speeds up over targets, giving you the audio feedback prospectors rely on for small, deep signals. Independent threshold and gain controls let you tune sensitivity to the ground you're hunting without losing stability.
Tight Spaces and Bedrock Crevices
The 5-inch DD coil maneuvers into narrow gaps between boulders, along exposed bedrock faces, and around sagebrush roots where larger coils can't reach. At 2.5 pounds, the Gold Bug Pro balances well for one-handed operation when you're working a crevice with a pick in the other hand. The static pinpoint mode with depth indicator helps you isolate a target's exact location before you start digging.
Why detectorists choose this
- Finds sub-gram gold nuggets in hot soil: 19kHz frequency and computerized ground balancing cut through iron mineralization that masks small targets.
- Fast target response in trashy ground: V-Break tone discrimination system lets you notch out iron falsing while keeping audio on gold, so you spend less time digging junk.
- All-day comfort on long prospecting hikes: 2.5-pound total weight and balanced design reduce wrist and shoulder fatigue when you're covering miles of desert ground.
- Real-time ground feedback: continuous readouts of ground phase and Fe3O4 mineralization levels tell you when to re-balance as soil conditions change.
- Simple learning curve for new prospectors: ultra-simple user interface with large LCD screen and two search modes (All Metal and Discriminate) gets you hunting in minutes, backed by our complete beginner's guide.
