Hi , i'm new hear , just got an se this spring , i started with factory setting , have done ok, the manual says keep the coil just off the ground , others say scub the ground, i'v read the post on scrubbing here and it seems the manual may be wrong ( am i right or wrong) I've tried all metal and manual sens . at 20 , so many signals , i was lost , it seemed the cursor on smart find would stay in the top left cornor unless i hit a target of any kind and then it would move , alot of chirping sounds , is that just the false signals or the high iron signals? When i hit a silver , copper or a good target of any kind will the pitch be high and the cursor at the top right side? May be dumb questions , but i sure could use some help>.. thanks in advance
