I was wondering if anyone has run into an issue like this before I have been using a whites V3I for about a year now and I purchased the 15x12 sef coil in October. I usually do most my searching in the relic setting and everything was working great for several outings until something happened. It had been visiting a site with large amount of dimes and quarters in the ground the type of place where at least every minute or so you had another target to dig but quite a bit of time went by without a good target and then eventually I realized it would not pick up quarters or dimes and wouldn't register anything higher than 40s 50s. So I packed up and went home and tried testing it and it worked. So a few days later with a charged battery I went back out and it started out fine and the same thing happened . since that time I put the double d back on to see if that did the same thing but weather and time has not been on my side yet. If anyone has any ideas or have ran into this before id be grateful thanks to however answers
