Fisher Gold Bug Pro Metal Detector Search Coil Combo

Gold prospecting in Arizona caliche or Nevada hot rocks demands a detector that holds stable ground balance when soil conditions shift between zones. The Fisher Gold Bug Pro runs a dedicated 19kHz frequency that penetrates iron mineralization without the chatter you get from broad-spectrum machines, and this combo ships with both a 5-inch biaxial coil for tight bedrock cracks and a 10-inch elliptical for covering wash gravel.

What's in the Box

• GoldBug Pro Metal Detector
• 5-inch biaxial search coil
• 10-inch elliptical search coil

Where the Gold Bug Pro Excels

Desert washes and dry placers

The 10-inch elliptical coil covers ground quickly when you're working a wash or old placer tailings. Ground Grab computerized ground balancing tracks through varying Fe3O4 levels without manual retuning, so you spend less time adjusting and more time listening for targets. The continuous ground condition readout shows you the ground phase value in real time, useful when you cross from decomposed granite into red clay streaks.

Bedrock crevices and specimen patches

Swap to the 5-inch biaxial coil when you're working tight spaces between boulders or chasing small nuggets in a known patch. The smaller footprint reduces ground noise in hot soil and lets you pinpoint targets against rock faces. Static pinpoint mode with depth indicator helps you isolate a signal before you start digging.

Relic hunting in mineralized farm fields

The V-Break variable breakpoint tone discrimination system lets you notch out iron while keeping mid-conductors like brass and lead in the accept zone. Discrimination mode with V.C.O. audio gives you a rising pitch on good targets, and you can run independent threshold and gain controls to tune sensitivity without losing the faint edge tones that mark deep relics.

Why detectorists choose this

• Finds sub-grain gold in hot ground: 19kHz operating frequency and computerized ground balancing handle heavy mineralization without masking small nuggets.
• Two coils for different hunt scenarios: 5-inch biaxial for tight spaces and bedrock work, 10-inch elliptical for covering ground in washes and fields.
• Less fatigue on long prospecting hikes: 2.5-pound total weight keeps wrist strain low when you're working a claim all day.
• Real-time soil feedback: continuous ground phase readout and Fe3O4 graphic show you what the ground is doing, so you know when to adjust settings.
• Backed by a five-year warranty: Fisher covers the detector for five years, longer than most gold prospecting detectors in this price range.
