My opinion exactly about the Fisher lines. They discontinued the CZ20, one of the best water detectors besides the Excalibur and I just have to see where First Texas goes with them.
Between the Garrett and the Tesoro, you will never be disappointed with the results of a Tesoro. An Garrett's warranty is not for LIFE. Otherwise it too is a good detector, but heavier than the Tesoro.
