Quick Scan use
What Quick Scan curve signatures tell you.
Moving the detector over the detected object gives a signature curve that
can help determine size and depth of the object.
What type of material might the object be?
Ferrous Metal signature curve
Red and blue indicate the bipolar magnetic characteristic of ferrous metal (magnetic) objects
Non-ferrous Metal signature curve
Ceramics and other materials.
Ground moisture can cause varying results. Re-scan on another day and at 90 degrees to the original scan orientation.
In volcanic areas, igneous rocks often retain a magnetic signature and can give confusing results.
