7.5.4 Scan Technique
The following technique applies only to the Mineral Scan mode
with the Super Sensor
(1) Ensure that all batteries and power packs have enough of a
charge to complete the scan entirely.
(2) Per the area to be prospected, ensure that you can travel the
desired path without any interruptions, pauses or large obstacles
(see explanation below).
The scan needs to be conducted in the following manner. Create a path where a single line can be
traversed. This path needs to be a longer path, usually greater than 20 meters in length. The normal
length for areas of prospection may be between 50 and 100 meters; up to 200m long. Areas of very
rough terrain will certainly be shorter.
This measurement needs to be a single line only!
