Hi,

I have a radio-control submarine and would like to have a form of diagnostic
equipment on my laptop taking readings from my sub. I can program with vb6
and pbasic but am looking for a method of communition. It would have to be
wireless, battery powered, cheap, not too big amd work underwater. Can
anyone recommend a way? Also how would I detect the amount of power the
battery has left on it?

Thanks Michael
