Why do I end up digging a trench instead of a hole?

[ashton9]

I'm new to THing and have about 10 hours of detecting under my belt. Occasionally I'll get a good nickel signal with no smear registered on the LCD. I'll pinpoint, dig it and recheck the hole and the signal has moved just to the edge of the hole. Well, I figure my pinpointing is off so I dig some more and recheck and the signal moves again, over and over and in the same direction. I quit digging the signal after the hole is around a foot long. I using a 1990 White's Spectrum Eagle.

8)SOMETIMES,IF THE OBJECT IS IN THE GROUND FOR A LONG TIME,THERE COULD BE A "HALO'SIGNAL SURROUNDING THE OBJECT;THAT IS WHEN SOME OF THE PROPERTIES OF THE ITEM IN THE GROUND LEACH INTO THE SURROUNDING SOIL,CAN MAKE IT HARD TO PINPOINT.
