THE MINELAB EXPLORER II
Discrimination
Discrimination is the ability of a metal detector to identify the user’s desired target (e.g. jewelry) and eliminate signals from undesirable material (e.g. nails).
The Explorer II can be programmed in a number of ways to discriminate against unwanted targets in different types of ground.
Full Band Spectrum (FBS)
When developing Full Band Spectrum (FBS) technology, Minelab’s scientists looked at improving the already successful Broad Band Spectrum (BBS) technology used in previous Minelab detectors.
Discussions with seasoned treasure hunters from around the world identified a number of possible enhancements for operators. The improvements to the Explorer II detectors include:
•increased detection depth;
•accurate identification of targets to greater depth;
•enhanced detection of desired targets amidst iron trash;
•adjustments to improve operation for searching
