thanks Steve
Watched both Digger Bob's video's. really good. So there is actually 3 tdi's, the TDI, TDI PRO, and the SL.
I,m thinking about a trip to Arizona/California next fall and I have the GMT but thinking the TDI would be a good weapon to add.
There is suppose to be a new non Minelab PI coming out of Australia shortly. Suppose to be a new concept in Pi's, so waiting to see if it materializes before I make the plunge. Not the QED. See what happens. Might be a repeat of the Pulse Devil story, although Mr Emory just applied for another patent.
Really enjoying your new forum! Lots of great info.
Cheers
