The detectors have changed as you can swing them a lot quicker depending on what recovery speed you're running, and yes, we should pass over all spots, but where I was, it's a huge beach so certain areas I will slow down and overlap each coil swing.but if I'm just walking around I just swing and hope I find a few targets.
@@jimfunnell gotcha. It's not like you are combing a farmers field for buried treasure. I still have my detector from the 1970s, a Coin Hustler 1. Very simple, no discrimination. Still works :)
