I'm still new to my Etrac and notice that sometimes when I have ended up with a coin I get pinpointing to work spot on, yet other times I seem to have the target visualized as to where the target should be, yet it may pinpoint off to the left or right a few inches and I get no signal where i expect to? Whats going on guys? Still learning here. I've noticed this the last few times I used my detector. Thanks for the help.
