search head is centred immediately over the metal object. As the object passes beyond the search head the sound
will quickly fade.
Detection Range
The detection range will vary depending on the size of the object, the length of time an object has been buried and
the type of ground the object is buried in. The best soil is compact soil, where you can locate coins at great depth,
especially if they have interacted with the salts in the ground, which makes them appear larger to the detector. The
worst conditions for detecting are in loose soil or freshly dug ground or when the object has only recently been
buried. Ninety percent of all objects are found within 6" of the surface. Adverse soil conditions can reduce the
detection range by as much as 50%.
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. He does this through careful analysis of the audio signals coming from the detector. You
should always listen for the specific characteristics of a signal. Determine over how large an area the contact
generates a signal to try and "outline" the object before you dig. Listen for the sharpness or dullness of the signal and
determine the strength of the signal. A coin generates a sharp signal, while the signal for a nail is vague.
7. Maintenance
The life of your detector is shortened by neglect or careless use.
Wipe the housing with a damp cloth and then wipe it dry carefully if you have used the detector in a hostile
environment (salty water, sand, etc.).
Salt Damage
Salty air can penetrate the control box in case of frequent use in a salty environment.
Parts of the electronic circuitry may corrode. You can protect your metal detector by covering the control box with
polythene.
The warranty does not cover damage caused by salty environments.
The Use of Solvents
Do not clean the housing with solvents or detergents.
Storage
Remove the batteries to prevent them from leaking if the metal detector is to be stored for long periods.
Troubleshooting
- check the batteries
- interchange the batteries and ensure the connections are correct and secure. Battery life can vary tremendously
between makes, therefore your "new" batteries may already have insufficient power to run your detector.
