Re: Disconnect for Tether at ROV?

Sea-ker,

I would be interested in this also. One question - have you considered putting a switch into the sub so only one uplink cable would be required? The only one external connector should be required.

compressed air tanks

Hi everyone, I am designing an ROV which will be using ballast tank(s) instead of thrusters. I am thinking of using compressed air rather than co2 (mainly for compatability wth diving systems, but alsl because I understand it's more stable) with a reducing valve.
