The Basics of Metal Detecting

Bounty Hunter™ metal detectors will detect any item composed all or in
part of metal. Most common and inexpensive metal detectors also detect
metal, but have three important limitations: discrimination, depth
detection and ground balancing. Bounty Hunter™ metal detectors, on
the other hand, possess superior discrimination, depth detection and
ground balancing capabilities.

Metal Types

• iron—a low-grade metal; iron objects range from nails and bolts to
valuable historical relics such as bullets, cannon balls, guns or
shackles.
• aluminum—a low-grade metal; aluminum objects such as foil or
cans are usually undesirable.
• zinc—a lower-grade metal; zinc is found in U.S. pennies minted
after 1982 and many newer, non-US coins also contain zinc.
• copper—a medium-grade metal; copper is found in U.S. pennies
minted before 1982.
• gold—a high-grade metal; jewelry or gold nuggets are gold items
sought by detectorists.
• silver—a high grade metal; jewelry or silver coins are silver items
sought by detectorists.

Discrimination

Discrimination is the detector's ability to identify the type of buried
metal or completely eliminate unwanted metals from detection.
Bounty Hunter™ Metal Detectors all have superior discrimination
capabilities, allowing them to differentiate between and identify
different types of metals.
Example: If you are searching for valuable coins in a park or beach,
you do not want to dig up pull tabs and cans. You canadjust
the Bounty Hunter™ detector so that it will emit a distinct
tone, or completely tune out these unwanted items so that
you spend your valuable time digging up only valuable coins.
