I recently took an interest in getting into Metal Detecting. A friend lent me his vintage 1970s White's Coinmaster V Supreme. Although in good general condition, it was suffering from its age. A wire had corroded and come loose from one of the battery terminals and the headphone socket needed looking at.
Anyway, I got it up and running and off I went. The machine was working fine when I stumbled upon a beach which was miles away from anywhere. Coke can, bottle top, ringpull etc etc, then whilst moving down towards the waterline, I put the head under the water to pinpoint an object. At this point the machine went and threw a tantrum.
When I got it back, I realised that although the coil was waterproof when new, 30+ years later, this was not the case. I have warmed the coil slightly using a hair dryer, and used low pressure compressed air to force out as much moisture as I can without slitting the casing open.
My questions are, is the case able to be split open without permanently damaging the internals? Is there a rubber o-ring that has possibly broken down over time leading to the leak? And, If the coil is indeed beyond repair, can I fit a later coil to it?
The exact model is a (UK Version) Coinmaster 5 Discriminator Supreme with a 4BDX Coil.
If it were mine, I would just go ahead and pull the coil apart, but since it is not, I want to return it to the owner in good working condition before looking at purchasing my own.
Many thanks in advance.
