Metal Detecting

hi all, i purchased a s/h deus with a 13 inch coil a few years ago. the coil went wrong (i think it's the battery) so reverted to the 9 inch and no problems, anyway after about a year it's about time i got it fixed so does anybody know where would be best to get in contact with?
obviously it's not under warranty,
cheers john

Regton are kitted out Jerry.
