Determining the Target Size and Depth
An operator who is familiar with his instrument will be able to do an excellent
job of determining object size, shape and depth before he digs. The
technique is learned from careful analysis of the audio signals coming from
the detector. Each time a signal is heard, listen for any peculiar
characteristics it may have ; determine over how large an area you get a
detector signal ; and try to "outline" the object before you dig.
CARE AND MAINTENANCE
The working life of you detector will be shortened by careless you or neglect
of the unit. Your detector is designed to withstand rugged handling on any
terrain, but mis-use or lack of due attention will tell in the end.
After using your detector in a hostile environment (salt water, sand, etc.), the
exterior parts should be wiped with a damp cloth using fresh water, paying
particular attention to the head, and carefully wiped dry.
Salt Damage
If you use your detector continually in a salty environment, particularly when
the wind is blowing off the sea, salty air can penetrate the control box.
Corrosion can occur in vital parts of the delicate electronic circuitry.
It is, therefore, recommended that precautions such as covering the control
box with polythene be taken to avoid damage.
The guarantee cannot cover such occurrences and any repairs needed
because of salt water or spray will incur a charge.
The Use of Solvents or Detergents
Solvents of detergents should not be used on the detector as they will attack
the plastic parts.
