The scanning wheel consists of 31 spokes with a plus or minus sign in the center. The wheel
rotates clockwise and the plus sign is displayed when moving towards a target of the selected
metal; the wheel rotates counter-clockwise and the minus sign is displayed when moving away
from a target of the selected metal.
When a target is passed, the plus sign changes to the minus sign and the MetalliScanner® tool
beeps. The plus/minus sign and the beep are primarily for estimating the general location of the
target. The plus/ minus sign change and the beep occur as you pass the target, but not necessarily
directly over the target.
To precisely locate the target, use the depth bars and the scanning wheel. The scanning wheel is
more sensitive than the depth bars but also has a built-in sensitivity change (similar to when a car
changes gears) around 3 to 4 inches. As a target gets closer, the wheel spins fairly quickly, but
suddenly slows down at around 3 to 4 inches. Once past this point the wheel speeds up again.
There is also a less noticeable sensitivity change around 2 inches. If this sensitivity change
interferes with determining the exact location of the target, you can press the calibration button
when you think you are over the target and then try to locate that target more precisely.
NOTE:
1. You then must start the pre-scanning procedure from the beginning to locate any other targets.
2. Calibrating over the target will make the depth reading inaccurate. Calibrating to determine depth
must be done away from targets. (See Calibration Section.)
Selecting the Operating Mode
The mode switch turns the MetalliScanner® metal finder on and off and simultaneously selects the
operating mode.
The switch has three positions: magnetic mode, non-magnetic mode, and off.
Move the mode switch to the magnetic mode position to find rebar, steel, iron, and other
ferrous metal.
Move the mode switch to the non-magnetic mode position to find copper pipe, brass,
aluminum, and other non-ferrous metal.
To turn the tool off, move the mode switch to the off position.
Note: The MetalliScanner® metal finder does a self test immediately after it is turned on. If the unit
does not pass the self test, you will hear a long, low-pitched tone and every other spoke on the
scanning wheel and all the depth bars will be displayed. If this happens, check this area for any
large metal objects and remove them. Then try turning the unit on again.
