Locating The Target; Sensor Head Null Zone; Coil Orientation - Minelab MF5 Operation Manual

Locating the target

When a target is initially detected, the Operator should stand in place
and continue to sweep beyond the target (Local Standard Operating
Procedure [SOP] takes primacy) in an attempt to find clear ground
beyond the target.
In doing so the Operator will:
• immediately gain an impression of the size of the target, prior to commencing mapping; and
• confirm the target is not in close proximity to a second target, thereby avoiding a possible
booby trap.
Once the Operator has obtained an approximate idea of the size and position of the target, the target
can be mapped for greater accuracy. Use the Target Edge Mapping and Target Pinpointing procedures
to map the target.

Sensor Head Null Zone

The detection response increases to a maximum when the Coil is over the target centre when in
Detection Mode. In Pinpoint Mode there is a maximum response when the target is below the left or
right side of the coil (on both sides), with a 'null zone' precisely centred over the target.

Coil Orientation

Approach targets with the long sides of
the Coil.
Avoid using the back and front of the Coil to
approach a target, as the target may not be
detected, or may be inaccurately located.
