Thanks for all your comments. I almost traded for a Minelab Xterra 30 instead of the Cibola. Dollar wise the Minelab is the better deal, more expensive than the Cibola but on sale now for the same price. The Xterra also has a display & three tone id. But the three tone id machines drive me nuts, and to me the display is not necessary. Not knocking the Xterra (because I have never used one) but I read some negative reviews such as : the detector shutting off on it's own,weak battery springs,headphone jack loosening up,display going dim with new batteries,no sound from internal speaker. I suppose there are bad one's in all different brands, I decided to go with the Cibola after reading so many good reviews here and other places, can't wait to get the Cibola and take it out for a long walk. Thanks! Steve.
