mag

Hello guys, I am a retired commercial diver. I have a project I am getting into and I am looking for some insight. I have an older aquascan wreckfinder Mc4 magnetometer unused. I want to connect this unit to my laptop. I know I can just buy a newer mag and do this but this seems like it's...

I am looking to buy or rent (or have repaired) a DISCOVERY Tone Mag 1A Fast Land Proton Magnetometer. I have one, but it has at least a shorted capacitor, which has the label sanded off. The manufacturer no longer makes or repairs them.
