Ok Ok it is the truth but not quite like you are thinking. Picked up the 6.5" coil yesterday. I wanted to detect an entrance onto the beach loaded with trash. I would dig a target and there was another target in the hole and another and another. Not only in the hole but along side of the hole. Each hole was a trench and got deeper and deeper because there was always another target in the hole/trench. Some of the holes were 2 times the length of the coil.deep before I ran out of targets. I was out 3 hours and only detected about 25'. The first picture is the trash and the last picture is what I found. All of that digging for 3 pennies and not even a wheat penny. The oldest was a 1970. Well you can see what a goof ball I am. I guess most wouldn't show their mistakes as huge as mine. I just wanted to show the results of 6.5 coil.
It is a good coil and it probably goes maybe 5"?....... Z
