I just received my cibola last week, as I wanted a detector that was simplier to use than my V3i . WOW I was simply amazed at this cibola!!! I actually believe it detects as deep or deeper than my V3i and Much simplier to operate. Get this, I found my First gold ring within 45 min. of opening the box of the Cibola, And I can assure you I went over it many times with the V and it probably gave me TOO Much information and I probably thought it was a bottle cap and didn't dig it. The Cibola gave a nice repeteable tone And I dug and found the ring 10" deep. I'm new a BIG tesoro fan to say the least!!
