IMPORTANT SAFETY INFORMATION

Electric shock hazard:
Always turn off power when working near electrical
wires. Contact with live circuits could result in severe
injury or death.
Eye injury hazard:
In situations involving multiple, closely spaced targets,
this tool may be unable to detect the exact location and/
or depth of each piece of metal. Always use caution and
wear eye protection when nailing, cutting, or drilling in
walls, floors, and ceilings that may contain metal
objects.
Failure to wear eye protection could result in serious eye
injury from flying debris.
• This tool only locates metal objects. Nonmetallic objects such as wood
studs and ceramic or PVC pipe cannot be located with this tool.
• If a magnetic and nonmagnetic object (e.g., rebar and copper pipe) are
positioned side-by-side or on top of each other, this tool may have
difficulty locating them.
• Do not wear jewelry, including watches, when using this tool. The metal
may cause inaccurate results.
All specifications are nominal and may change as design improvements occur. Greenlee
Textron Inc. shall not be liable for damages resulting from misapplication or misuse of its

The display has indicators that indicate status and show information about
detected objects (targets).
There are three status indicators: low battery, audible, and silent icons. The low
battery icon is displayed when the battery has less than five hours of use
remaining. The audible icon will always be on when the unit is in the AUDIBLE
mode. In the SILENT mode, the silent icon will be active.
The remaining icons indicate information about a target:
• The magnetic icon is displayed whenever the unit detects magnetic material,
• The depth bars represent the depth of the target. Depth is indicated in both

Turning the SF-780 on and off
The three-position mode select switch turns the unit on and off and selects
either audible or silent operation.
Turn the unit on by moving the mode switch to either the AUDIBLE or SILENT
position. This should be done in air and away from any metal.
The SF-780 performs a calibration immediately after it is turned on.
Note: If the unit fails to calibrate, you will hear a long, low-pitched tone and all
the depth bars will be displayed. If this happens, check the area for any large
metal objects and remove them or move the unit to a different location. Then try
turning the unit on again.
To turn the unit off, move the mode switch to the OFF position.
The auto power off feature turns off the unit after five minutes of inactivity. After
it turns off, the unit loses its calibration.

changes to the minus sign and the SF-780 beeps (in the AUDIBLE mode).
