UXO Coil

The standard coil for the F3 detector is a 20cm (8inch) mono loop coil, This is ideal
for searching for very small metal targets, in particular minimum metal mines.
However, when there are no minimum metal mines in the area of operations and the
targets being sought are large and deep a larger coil size will often give better results.
The F3 UXO coil is a 44cm (18inch) mono loop coil, this will give a stronger signal and
greater depth of detection for large metal targets but a weaker signal for very small
targets.
An F3 detector with the 20cm (8in) coil can be converted to an F3 UXO detector by
removing the 20cm coil and connecting the 44cm (18in) UXO coil. Alternately an F3
UXO detector can be converted to an F3 by removing the 44cm UXO coil and replacing
it with a 20cm (8in) coil. Changing coils on the F3 detector requires the correct tools
and a level of technical competence. Figure 24 shows the parts of the UXO coil.
Do not use the F3 UXO coil if there is any possibility of minimum metal mines in the
