The 6000 Pro line is probably the best detector Whites ever made. The analog meter is dead on and provides good consistent info. I have a 6000 pro SL and it's a fun detector.
Worth noting that the XLT is the same detector except for the digital screen and a lot harder to program...
Just took mine out for its last hunt for a while after work today. Not putting her out to pasture, neccesarily but the upgrade I've been researching and saving for months for comes in the mail on friday!
I sure have had fun learning on that machine over the past year. Bought it at a pawn shop in alabama and it started a serious addiction! And that meter is dead on despite its age.
