Thanks Nugget, yes I think its time for a new detector. The coil is showing its age but still performs well (thank god for duck tape), the only change I've done was to remove the 8 AA's and now have a carry pack 12v,its ok at least I can recharge, it use to cost a fare bit replacing the 1.5's. Is there is any other 15000 swingers out there? Once again thanks for the welcome.
