Changing Endcaps

• A unique feature of the F3 is its ability to change sensitivity through the

exchange of Sensitivity Endcaps. This design feature eliminates the

possibility of an operator selecting the wrong sensitivity through manipulation

of dials or switches. The Sensitivity Endcap provides an obvious visual cue

that confirms the level of sensitivity selected in the F3. The F3 is supplied

with one Black (maximum sensitivity) and one Red (low sensitivity)

Sensitivity Endcap.

• The F3 can be used with Black or Red Sensitivity Endcaps.

The decision on which Endcap to use will be provided by the

local authority.

• To change a Sensitivity Endcap:

o Ensure the F3 is switched off.

o Place the thumb of one hand in the centre of the Endcap and curl

the fingers under the base of the Endcap.

o Gently push inwards with the thumb and simultaneously pull the

base of the Endcap away from the Electronics Pack.

o Fit the selected Endcap by gently positioning the inside of the

base of the Endcap under the base of the Electronics Pack. Using

the palm of the hand, apply light pressure to fit the Endcap into

position.

• The Black Endcap is for Maximum Sensitivity.

o The Black Endcap MUST be selected when searching for

minimum metal mines or when maximum clearance depth is

required.

• The Red Endcap is for Minimum Sensitivity.

o This feature may be useful when there is a need to ignore small

metal fragmentation on the surface but still detect large targets at

depth.
