I am looking to trade my Minelab Quattro + cash for an Explorer II in good condition. I am only interested in an Explorer II so I will not consider trades for anything else. My Quattro is 6 months old, is in great shape and perfect working condition. The manual, Andy Sabisch's book and the Minelab display cover are included. It has the standard battery pack with 1800mA NiMH batteries. No charger. The Quattro is a great machine but the detecting bug has bitten and I am interested in getting something similar but more tweakable. Obviously, I am willing to put a reasonable amount of cash in the deal; certainly the difference between the typical used price of a Quattro and an Explorer II but that's negiotiable.
