Analysis of Scanned Data
First here is some general info on the cross hairs and data screen.
You can both determine depth and size using the XL16 IMAGER PRO software. After
performing a scan, bring up the scan in the software. Using the purple and black arrows
(cross hair buttons) on the left move the crosshairs over your target. Right click change
perspective (This is very important for depth) and then right click show data under
crosshairs. This window has the depth in meters on it as well as the strength or weakness
of the target. To determine the size of the target you also use the crosshairs. So depending
on the unit you can count the sensors in the scan and determine how many inches wide the
object is in the scan. Using a XL16 IMAGER PRO with a 16 sensor antenna; count using
the crosshairs over from left to right starting with 1 because the first position gets
information. So each 16 sensors over is 24 inches per 16 sensors. So say the scan is made
up of 4 rows and the target completely fills two of the rows we can determine that that the
object is 48 inches wide. Now to determine length, we have a person, imagine how far they
can walk in one second. So if that is 2 feet, every six clicks up using the crosshairs is one
second. So say the object covers 6 clicks that would be equal to 2 feet so we now know that
the object is 24 inches long and 48 inches wide. Data value is the strength of the point
relative to the ground balance zero point. The relative strength or weakness of a target is
important in determining which spot is amplifying the milligauss or dampening the
milligauss. Strong or weak values may be important for determining the best place to dig
or whether to dig at all, variation in soil mineralization and other important information.
Depth of point should not change when the data value is changed but the data value
should only be changed to create reminders as it will no longer be correct information.
Analysis of data is by far the most important of all operations with the XL16 IMAGER
PRO. Even though properly conducting the grid pattern is 90% of the task, identifying the
target is the entire purpose of owning the XL16 IMAGER PRO. Take note of the locations
of the scans and properly note your locations to find them again. Review your data
immediately in the field. Very strong or very weak signals (Figure 3.10) should be marked
for further scanning. Be sure to re-scan any strong anomalies to see if they are repeatable.
The technique “Double Xing” is critical in the process of pin pointing the location. If an
object is suspected to be in a particular location and further scans show that the object is
constantly moving, be suspicious of mineralized soil conditions in the area. Real targets do
not move, although the shapes that appear on the laptop screen may change.
