Aladin/Uwatec oil

[ffhamm]

I know this question has come up in a couple of threads, I have never found a great answer.

Does anyone know if the oil inside these computers/compasses is mineral oil, silicon oil, or something else.

Changing the battery in a True Track compass, and maybe in a Air X if scubapro wont give me enough incentive to trade it in.

Thank you,

Jeff

My Sport Ultra started showing "ERR" last year so I looked into it also. This is all I found - on a website in England as I recall:

the oil is insulating oil (available from some electronic shops or pump service agents what they use in high voltage transformers)
