hello all Tesoro lovers, want detector for small items. use explorer and like it but in some situation its to slow. under bad have cibola but somehow dont like it after one year using it. few days ago tested tejon and cibola in my well know and with explorer worked iron place and found more targets---I suspected it--, but cibola was not so fast and not so clear on the targets as Tejon. my question is,do I have to buy Tejon or cibola after puting GB manual and changing to 18Khz can be the same Tejon? thank you Stasys
