VR3 gets a lot of publicity in the tech magazines for trimix diving. If you plan to use this ultimately, you could buy it now.

The other viable option is save your money and rather than get a computer at all, get an Uwetec bottom timer, and plan your dives off tables with it, or else use EAN 35 on all dives, and limit your depth to the NACD cavern limit of 100ft.

EAN 35 lowers your equivalent air depth to less than 65 ft for all diving, and therefore you would not need to be concerned with NDL times, as long as you are only diving with a single 80 cu ft tank.

You SPG then becomes your dive computer.
