23 F1A4 Operator Instructor Notes and Syllabus
Minelab Countermine Division
Safety through Excellence
•
C - Three similar targets in star shape (three Test Pieces).
This brings out the lesson that
they must sweep forward to clear ground. Some will note the first two targets and forget the
upper third one. The good operators will actually be able to state that there are three targets.
That is an excellent response but all you should seek from this exercise is that the student can
accurately map the “suspicious area” that they will investigate by prodding.
•
D - One large target right on the edge of the lane.
To prove that not all mines are
conveniently located in the middle of lanes.
•
E - one small target (single Test Piece).
Make as difficult as you want, but achievable.
The following is a suggested evaluation standard using inert mines – targets should be pinpointed to
within 10 cm of centre:
•
T72a at 15cm (or similar minimum metal mine buried at maximum detection depth).
•
PMN or equivalent at 20cm.
•
Small different targets 10-15 cm apart.
•
Large metal anti-tank mine at 30 cm.
•
2 small identical targets 7-10 cm apart.
•
Small anti-personnel mine near metal anti-tank.
