Collecting Data and Marking Targets with ScanMax
It is always easier when locating to proceed from the “known” to the “unknown.”
With that in mind, spend some time walking over your survey area before turning on
your UtilityScan. Note the presence of any surface feature which could indicate the
location of buried utilities. Are there manhole covers, power poles, valve caps, fire hydrants, old markouts, etc.?
Try to begin your survey at one of these features. In the instance of a manhole cover, move sufficiently far from it
to avoid imaging the concrete catch basin or box and move the UtilityScan in straight lines in a box pattern on all
four sides. Note the presence of any hyperbolas which could represent a pipe.
GPR will best image pipes when you cross those pipes at a 90-degree angle. Your survey lines should always be
positioned to cross the target you are tracking at a 90-degree angle.
