[QUOTE="AuMan, post: 195431, member: 2670"] Power it up without the coil connected. If it doesn't make the beeping then most likely the battery is worn out. If you have a multimeter, measure the battery voltage with no load(not connected to the detector). It should be between 6 to 6.7v. Then measure the battery voltage with it connected to the detector, with a coil, detector turned on. The voltage should not drop below 5.8v as this is where the low battery warning is set to. Typically it will drop only a small amount, 0.1-0.2v when load is applied. If you don't have a multimeter, try your nearest Jaycar store. I'm sure they would be happy to test it for you. They also sell replacement batteries. [/QUOTE]
