VLF vs Pulse Induction Metal Detectors: What’s the Difference?
1. Introdouction
VLF vs PI
One of the first major decisions every detectorist faces is choosing between VLF and Pulse Induction (PI) metal detectors.
They work very differently—and choosing the wrong type for your conditions can ruin your experience.
2. What Is a VLF Metal Detector?
VLF (Very Low Frequency) detectors use continuous wave transmission.
Strengths:
Excellent target discrimination
Lightweight and energy-efficient
Ideal for parks, fields, and coin hunting
Weaknesses:
Struggle in highly mineralized soil
Reduced depth in extreme conditions
Best for:
Beginners
Coin and relic hunting
European inland sites
3. What Is a Pulse Induction Detector?
PI detectors send powerful pulses into the ground.
Strengths:
Extreme depth
Handles mineralized soil extremely well
Excellent for gold and beach hunting
Weaknesses:
Very limited discrimination
Heavier and more power-hungry
Best for:
Gold prospecting
Saltwater beaches
Highly mineralized ground
4. Which One Is Better for Europe?
For most European detecting:
VLF detectors are the practical choice
PI detectors shine only in specific environments
Unless you hunt:
Gold-rich soil
Black sand beaches
Extreme mineralization
VLF will give better results overall.
