unit and sets the sound level.
SEnS - Sets the sensitivity level of the unit. Zero
setting is the lowest level and 10 is the highest.
For general use, set the sensitivity to a higher
position. In a mineralized area, or area with electrical
interference, a lower setting may be more effective.
MODE - Sets the unit to three modes:
DISC, ALL METAL and TONE.
target Button - It is used with ALL METAL
mode to pinpoint a target object's location.
DiSc/tOnE - Adjustment knob for metal identification.
View Meter - Registers signal strength
when a metal is detected.
- DISC, ALL METAL, and TONE are motion modes. You
have to move the Search Coil to find your target object.
- Target Mode is for pinpointing the location of
the item when the item is below the surface.

Before Getting Started

Before beginning an outside search, you must test
the unit with samples of metal. Use the following:
• an iron nail
• a five-cent coin (nickel)
• a one-cent penny (zinc coin, after 1982)
• a 25-cent silver quarter.
Place the Metal Detector on a wooden
or plastic table with the Search Coil face
up. Make sure the table is away from TVs,
computers, or any device that can cause
electromagnetic interference. See Figure C.
Figure c
nOtE: Be sure to remove any watches, rings, or
other metal objects on your fingers and hands.
Turn on the Metal Detector and set the VOLUME
dial to the middle position. Set the MODE switch
to the middle (ALL METAL). See Figure D.

Sweep the metal samples 2 to 3 inches or more
above the center of the Search Coil. The Metal
Detector will respond to each with a "DI" tone and
the pointer on the View Meter will swing to the right.
nOtE: Be sure to move the samples, as
the Detector is in motion mode. Otherwise
the Detector will not respond.
nOtE: Adjusting the SENS dial from "0" to
"10" will increase the Detector's sensitivity.
Use the DISC/TONE dial to search for
specific metals by having it not detect
("differentiate") other kinds of metals.
