i have had the v3 for 3 weeks now and have found lots of clad ,2 rosies and 1 small ring. mostly in cj program and modified hipro. i was starting to build some confidence until the last 4 times out. the machine would stop reading and i would have no audio. i would be swingin away fine with vdi working, depth workin and all of a sudden id only see a depth in upper left corner with nothing else happening. so id get apenny or quarter out and swing in front of the coil and there would be nothing. i would click the trigger back twice and nothin, id click once and nothin. id change programs and come back and it would work fine. i would be in cj program id ground balance check sensitivity in 6 block and set rx at or below what it recommended. when workng works great. but when youre going along and after 10-20 feet you find its not working makes you wonder what youve missed. i was just wondering if anyone else has run into this. any recommendations would be appreciated. i hope its something im doing and not the machine. other than that i think its great.
