You  can  set  the 

DISCRIMINATION

  control  to  minimum  (fully  anticlockwise),  to 

maximum  (fully  clockwise),  or  anywhere  in  between.  As  you  set  the 

DISCRIMINATION

 control to higher levels, the detector first does not detect small 

pieces of aluminium foil, then thick foil, and finally metal objects like pull tabs from 
aluminium cans. 
Note:  Each  time  you  use  the  detector  in  a  different  area,  you  must  adjust  the 

DISCRIMINATION

. Each search location presents new challenges. 

FALSE SIGNALS 

Because  your  detector  is  extremely  sensitive,  signals  caused  by  buried  rubbish, 
and other sources of interference might cause signals that seem confusing. The 
key to handling these types of signals is to dig for only those targets that generate 
a strong, repeatable signal. As you sweep the search coil back and forth over the 
ground,  learn  to  recognise  the  difference  between  signals  that  occur  at  random 
and signals that are stable and repeatable. 
To  reduce  false  signals  when  searching  where  there  is  a  lot  of  buried  rubbish, 
scan only a small area at a time using slow, short overlapping sweeps. 

DETECTION HINTS 

No detector is 100% accurate. Various conditions influence metal detection. The 
detector’s reaction depends on a number of things: 

 

The angle at which the object rests in the ground. 

 

The depth of the object. 

 

The amount of iron in the object.  

 

The size of the object. 

PINPOINTING A TARGET 

Accurately pinpointing a target makes digging it up easier. 
Accurate  pinpointing  takes  practice,  and  we  suggest  you  practise  finding  and 
digging  up  small  metal  objects  on  your  own  property  before  you  search  other 
locations. 
Follow these steps to pinpoint a target. 

 

Sometimes,  targets  are  difficult  to  locate  accurately  due  to  the  sweep 
direction. Try changing your sweep direction to pinpoint a target. 

 

When the detector detects a buried target, continue sweeping the search coil 
over the target in a narrowing side-to-side motion. Make a visual note of the 
exact spot on the ground where the detector beeps. 

 

Stop  the  search  coil  directly  over  this  spot  on  the  ground.  Then  move  the 
search  coil  straight  forward  away  from  you  and  straight  back  toward  you  a 
couple  of  times.  Make  a  visual  note  of  the  exact  spot  on  the  ground  where 
the detector beeps. 

 

Repeat  Steps  1-2  at  a  right  angle  to  the  original  search  line,  making  an  “

×

” 

pattern.  

 

The  target  should  be  directly  below  the  “

×

”  at  the  point  of  the  loudest 

response.
