TONE DISCRIMINATION (continued)

(Toggle switch to the Right) Classifies

detected metal objects by emitting a low or high tone.

Adjust the DISCRIMINATE control higher to increase the range of the low tone. It is possible to set the DISCRIMINATE level so

that nickels have a low tone, larger coins have a high tone, and pull-tabs have a low tone or in-between “broken” tone. The

"broken" tone makes pull-tabs and trash easily recognizable. Sensitivity will be reduced slightly when using the Pioneer 101 in the Tone

Discrimination mode. If you want optimal depth capability, operate in the All Metal mode by turning the Discriminate control

completely counterclockwise; then turn the

Sensitivity control clockwise to its highest

clockwise position without chatter. If your

Pioneer 101 chatters or beeps erratically, reduce the Sensitivity by turning the left knob counterclockwise.
