I have a "new" Troy X3......lifetime warranty card is included because it was never sent in. It comes with the 7" concentric coil and is a beautiful machines. This detector is a true turn on and go lightweight powerhouse. The Troy X3 uses one 9v battery which last about 25 hours and weighs only 2.2 lbs with battery installed. I will also add Labtec headphones with volume conrol to go with it. I am looking for a Fisher F70 and hope to work out a trade with someone who has one. Let me hear from you about what you have.
