Minelab F3 Mine Detector Operation Manual page 7

1.3 The F3 is a robust detector that is extremely simple to
operate. There are no complicated controls resulting in the operator
being able to focus on the vital task of mine detection. If mine
detection occurs in a "difficult" environment that includes highly
mineralised ground or electrical interference from overhead power
lines or other sources, simple and quick semi-automatic procedures
can be initiated by an operator to allow the detector to continue
performing at maximum capability.
1.4 The F3 incorporates several safety features such as Low
Battery and Fault warnings; audible confirmation at the completion of
specific operational procedures; and continuous microprocessor
controlled internal self-testing. The inclusion of a Test Piece
provides an operator with a quick and easy test to ensure the
detector is working to its operational capability.
1.5 The F3 can be supplied with an optional Light Emitting
Diode (LED) display and Volume/Sensitivity Control.
configuration, the detector is known as the F3L.
1.6 Components of the F3 are manufactured within tightly
controlled parameters so that they can be interchanged in the field
without any requirement for calibration.
1.7 The F3 is designed to satisfy MIL STD 810F:
Method 512.4 Water Immersion (IP67)
Method 514.5 Vibration
Method 516.5 Shock
Although the F3 can withstand immersion to a depth of 3m for short
periods of time, it is NOT designed for use as an underwater
detector.
