OPERATOR CONFIRMATION EXERCISE 

 

The  Operator  Confirmation  Exercise  is  used  to  confirm  all  training  objectives  for  the  course.  

Instructors  can  decide  to  what  degree  the  exercise  can  take.    For  example,  it  can  include  a  theory 

evaluation with oral questions being given to the student.  However, as a minimum each operator must 

demonstrate proficiency in the use of the detector by entering a previously prepared test area.

 

 
For an operator to be deemed proficient, all targets within the test area must be detected.  If a student 

fails to detect all targets, he should be permitted to attempt the Confirmation Exercise as many times 

as necessary in order to pass.

 

 

An example of an Operator Confirmation Exercise Sheet is included at the end of these Instructor Notes. 

 

Equipment 

 

  Cleared evaluation area – constructed as one mine lane (1m wide and 5m long).  

  Targets to bury in the test area as described below – if inert mines are not available, F1A4 Test 

Pieces buried at varying depths will suffice. 

 

Training 

 

As each student comes to be evaluated, make then go through the normal start-up procedures and 

also Ground Balance on your mineralized rock, brick or roof tile.  They should then Ground Balance 

the detector as close as possible to the evaluation area.  Earsets must be worn.  
 

 

Sweeping drill.

  Ensure the students sweep with the Coil parallel to the ground, and as close as 

possible to the ground (observe local procedures) and that they overlap the front, rear and sides of 

the area by one half Coil width (100mm/4ins).  In addition as they progress up the mine lane, they 

should  advance  the  Coil  one-half  Coil  width  (100mm/4ins).     When  a  target  is  initially  detected, 

always sweep beyond the sound of the target to cleared ground before commencing pinpointing 

procedures.
