identification system automatically classifies metal objects into three
categories with three different tones—low, medium and high. It makes it easier
to identify the type of the target being detected.

Low tone for: bottle caps, nails, small gold ring and nickel (5¢)
Medium tone for: pull-tabs, S-CAPS, zinc pennies or 1¢(post 1982)
