8.2.2 Parallel or Zig-Zag?
For skilled users of the Fusion Light both scan modes are suitable. According to experience the best graphics
has been received in the "Parallel" mode, because you are starting at the same point and traveling in the
same direction. It is also easier to control your walking speed.
Especially in uneven territories like mountain sides, acclivities or other inclined layers the parallel mode is
preferred. When it comes to speed, the experienced user will very often use the Zig-Zag mode for the initial
scan to determine if there are anomalies in the area worth further research.
8.2.3 Tips from the trainers themselves
When conducting scans, there are some extremely important items that need to be noted. First of all it is
crucial that you relax. When you are tense, you are putting too much pressure on yourself to do the scan
correctly; often resulting in errors.
•
Newly buried targets are difficult to see. Many users receive the equipment and the first thing they do
is go out and bury an object. When an object goes into the ground it changes the natural signature of
the soil and creates some kind of noise. Usually the buried object has a weaker signature than the
unnatural noise and therefor is not detectable. So taken scan images will not show the buried item
but visualize the noisy area in blue colors. After the item has been seasoned, meaning it has been in
the ground for a complete cycle of seasons (usually a year), the noise gets reduced and the signature
of the buried object becomes visible again.
•
Train on known targets. In the training course at the factory we have several objects that have been
buried for years, just like real targets in the field. These targets can be quickly and easily identified
because they are not natural to the soil. Other targets that you can use in your own area are buried
utilities. Pipes, tanks, electrical, sewers, graveyards, etc... Most of these items can be found in every
community, town or city. This is where you need to begin your training if you are going to self-train.
•
Get professional training. When you take advantage of receiving the training, either from the factory
or a qualified dealer, you will understand not only the use and operation of the OKM detector but also
the software so much easier and be able to identify targets as well as errors.
•
Do not rely on just one scan measurement. So many users go out into the field and they make a
measurement and see a target. Instead of repeating the scan and reproducing it several times, they
go out and get a shovel and dig. On very rare occasion will the first scan be perfect. Even the trainers
do multiple scans to ensure that they are not looking at areas of mineralization or an error.
•
Soil Mineralization – Oh! Very frustrating! We will all experience it. When you are in an area that is
known to have pockets of mineralization, be prepared to conduct more scans than normal.
