Hi, I’ve had my pulse dive for over a year, used it mainly as a pin pointer. I’m in the Mediterranean and using it in the sea. For some unknown reason it has lost sensitivity and only detects a euro coin when placed directly on the coil. Will not detect anything else and or any depth. Any suggestions please and thank you.
