I sent one of my Cibola's to AZ to get fixed. It wouldnt do anything. Come to find out I am a little harsh on it, looking in briars, tree tops and real thick places and I had nicked the insulation next to the coil. I use it for relic hunting. I just got it back today. Has been gone 13 days. Got a nice letter from the folks at Tesoro telling me what they had done to it and what I should do to keep this problem from happening again. I was/am impressed. Less than 2 weeks and I got it back. I hope tommorow is pretty 'cause I am gonna take it out...d2
