The first three are self-explanatory. The last one can be executed in one move. Just make the oval with your coil and when you get back to the starting point ( either end of the oval ) just scan across the middle and when you get to the end start the next oval again. This one probably covers the most ground six to eight inches down where the signal is only covering an area the size of a half dollar or a quarter ( depending on what depth the target is ). These scans will cover more at depth than the old standard of overlapping.
