Rob, I thought I understood pinpointing and how it worked, but I'm thinking now I have no clue. If an object, such as a coin is detected, does the pinpoint bars go out a shorter distance than say an aluminum can? (How long the bars are indicate the signal strength. A surface quarter could have the same length bars as a very deep can.) So if that is true, the bigger the object, the longer the bars stretch out. (You still have to consider depth.) Also, if you have an object and the longest bar is RED, does this mean it's probably junk? ( NO, Vdi 78 and red could be a dime.) What if it's BLUE? ( depends on the Vdi. Blue and Vdi 19 could be a nickel.) I was in the thought that the longer the GREEN bar, the better a chance of silver. (Vdi 70's and up with green bars could be clad or silver.) I have read and re-read my manual and don't think the bars are explained well.......at least for my little mind. Can you explain it better?
