Ok, After a year with my V3, I have still not sent it in for the software updates. I never felt it necessary, because I have had great finds. My D2 coil has been a little "spotty" working 100% at times, but I think it has finally kicked the bucket for good. Has anyone with an original Vision V3 sent it in and had improvements on consistency, depth? I hope they will replace my D2 coil as it still looks New, as does the detector.
