have used this wonderfull device. have bought in states about six month ago. in my country service and sending abroad for it is not an option. so authorised service is unavailable. since i have bought and start using large bulgarian ultimate dd coil there was no problems. device detected gold and silver targets at pretty good depth.
then a coil encountred a short circuit break on a female connecter of a coil. defect was corrected. but the depth of targets decreased by two-three times. changing coil makes no sence. the depth is shallow. local electronic experts could not set the diagnose for this problem. there is possibility to send to authorised centre, so i would be glad to hear all kind of advice from members of community who had similar experience.
best regards, Edward
