I've noticed that the pinpointer on my Eurotek Pro nulls quite a bit and that I will have to release the button and try again sometimes more than once. It's really not that much of a problem because it is really easy to pinpoint without the pinpointer, but it is annoying when trying to check a deeper target. Was just wondering if anyone else was having this problem. I really love this detector and would like to know why this is happening. Thanks
