Traded a little colour for one of these as an upgrade for my old sovereign GT, and to try and get the kids interested.
Came with users manual and a copy of "Mastering the ML Quattro by Andy Sabisch".
While I'm yet to give it a proper swing, events will see a change in local soon. This means greater travel time to the goldfields for me, but more relic and coin areas opening up. Will let you know how both Quattro and supplied material go, as opportunity to discover both arise.
PS. I also have a 15"DD WOT coil i used for beach/coin chasing in days past on the Sovereign, I'm keen to see if the Quattro can handle.....
