Been reading tab's posts about the Cibola and then an article on a field test where several costly high end detectors were tested and the Cibola was the only one to give ANY indication there was a target. Not a good signal, mind you-just a little beep. I can't stand the temptation any longer. First, I wanted to see if changing the frequencies actually affected the g/b. Secondly, I wanted to try switching from disc to pinpointing (a/m) and try signal comparison techniques that Monte wrote an article about. Thirdly, I MAY add another tab check switch like I did on the Silver umax and call it the Tebola! Surely this will be my LAST detector
