Understanding Different Metal Detector Technologies
When you’re selecting a metal detector, the technology driving its performance determines what you’ll find and where you’ll succeed. VLF systems excel at discriminating coins from trash but struggle with soil mineralization.
Understanding your detector’s core technology isn’t optional—it’s the difference between walking over treasure and actually recovering it.
Multi-frequency detectors transmit simultaneous signals, delivering superior target depth and stability across challenging terrains—beaches, parks, mineralized ground—without requiring multiple passes. Modern SMF technology also enables waterproof operation down to 16 feet, allowing you to detect in shallow water and wet environments without compromising performance.
Pulse Induction technology cuts through heavy mineralization for maximum depth on gold nuggets and beach targets, though it can’t distinguish between metal types.
Relic hunters benefit from lower-frequency VLF units engineered for deep penetration and iron rejection. Consider the terrain’s characteristics when selecting technology, as rough fields and deep water conditions require detectors with specific durability features.
Advanced features like gradiometer coils, differential antennas, and Multi-IQ processing (5-40 kHz simultaneously) enable you to adapt quickly, detect efficiently, and recover targets other detectors miss.
How Target Identification Systems Work
As your detector’s search coil sweeps across the ground, it emits an electromagnetic field that penetrates soil and induces electrical currents in buried metal objects. These energized targets generate return electromagnetic signals that your detector’s coil receives and analyzes.
The electronics measure conductivity and inductance by evaluating phase shifts—the delay between transmitted and received signals. Highly conductive metals like silver create larger phase shifts, while zinc pennies produce smaller ones.
This analysis transforms into Target scoring from 00 to 99. Low values (0-40) indicate iron and foil, mid-range (40-70) suggests aluminum, and high numbers (60-99) represent silver and copper. Audio tones complement these visual readings, with high, clear tones signaling conductive targets like silver and low, grunting sounds typically indicating iron.
However, target orientation dramatically affects accuracy—flat coins deliver reliable readings while edge-standing coins produce erratic numbers. Eddy currents form in the metal when the electromagnetic field penetrates the target, creating the measurable response your detector interprets.
Multi-frequency technology provides the most stable performance across varying conditions.
