I sent my old Bloodhound in for repair last week and was notified by Garrett that it needed a new front coil and for that reason couldn't be repaired. They said they no longer have any coils for that unit. . . . Anyone know where I can purchase a front coil (or a whole new unit) for a Garrett Bloodhound 5 pin? I use the Bloodhound with my old Garrett ADS III.
