A VLF metaldetector will be more sensitive to big coins and metal objects, and morecomfortable to detect in weakly polluted land of small ferrous and homogeneousfield.
VLF detectors are: smallest, lightest, most portable, easiestto operate, and most economical.
Not as sensitive to electrical interference.
VLF metal detectors need Less Power.
2. VLF Drawbacks:
VLF detectors will also produce so much noise that evenhearing a target will become impossible, basic coin machines will almost alwaysreact in the same way, they will squeal
like a stuck pig with each swing.
There are areas thatthey will not handle and their depth ability is seriously effected.
Hot rocks and mineralisation will affect the VLF machine muchmore than the PI detectors.
Not very efficient indiving detection
3. VLF Examples:
FS2, GF2 and other many models.
