The detector requires a single 9-volt
ALKALINE
battery (battery not included).
Do not use ordinary zinc carbon batteries.
Rechargeable batteries can also be used.
If you wish to use rechargeable batteries, we recommend using a
Nickel Metal Hydride rechargeable battery.
The battery compartment is located on the back side of the housing.
Slide the battery door to the side and remove it to expose the battery
compartment.
BATTERY LIFE
Expect 20 to 25 hours of life from a 9-volt alkaline battery.
Rechargeable batteries provide about 8 hours of usage per charge.
SPEAKER VOLUME AND BATTERY CHARGE
You may notice the speaker volume drop while one battery segment is
illuminated.
With one segment flashing, low speaker volume will be very apparent.
For loudest speaker volume, select 1 or 2 tones under the # OF TONES
menu selection.
BATTERY INDICATOR
The 2-segment battery indicator has 3 stages of indication.
These indications are accurate for a 9-volt alkaline battery.
Segments Illuminated
Battery Voltage
2 -segments
more than 7.6 volts
1 -segment
more than 6.2 volts
1 -segment flashing
less than 6.2 volts
After the battery indicator begins flashing, expect the detector to shut off
within 10 minutes.
A rechargeable battery will usually illuminate both segments throughout
most of its useful charge. But as soon as it drains to the 1-segment level,
it will then discharge very rapidly.

Pull Tabs, Nickels,
& Smaller Gold

In DISCRIMINATION mode, targets are identified both audibly and
visually as follows:
1. Different pitch tones for different types of metals
2. A 2-digit target I.D.
3. An illuminated icon within the target category best describing it
The detector must be in DISCRIMINATION mode to identify targets.
The ALL METALS mode does not provide target identification.
AUDIO TARGET IDENTIFICATION:
When in the default 4-tone mode, tones identify targets as follows:
BASS TONE
Ferrous objects, such as iron and steel, like nails and tin cans.
Smallest-sized gold objects and steel bottle caps
LOW TONE
Foil, pull-tabs (some new style), nickels, steel bottle caps.
MEDIUM TONE
Newer pennies (post-1982 are minted from zinc)
Larger gold pieces, small brass objects, and most bottle screw caps.
Most recent-vintage non-US coins.
Pull-tabs (old style, some new style)
HIGH TONE
Silver and copper coins, large brass objects
Older pennies (pre-1982 were minted from copper)
Dimes, quarters, half-dollars, silver dollars
Susan B. Anthony and Sacajawea dollar coins
Flattened aluminum cans (with a stronger signal than a coin)
