CTX Pinpoint trace shapes on the screen
I noticed yesterday that when using pinpoint trace different targets make different shapes on the screen. Has anyone noticed any patterns which indicate what lies beneath before digging?
Twice iron signals gave a long trace like a lightening bolt that stretched from top to bottom of the screen on a slant.
One copper penny close to the surface gave a sausage shape and all the others that gave a trace were roundish or clumped together!
Any thoughts or ideas appreciated here, apologies if it's been mentioned before
