I tried the Prism unit a while back, and found it to be well suited for using multiple tanks. I'd bet it would be a simple matter to adapt it to an application like what you described. Or, for that matter, side-mount the Nitrox bottles, and switch to them for deco. This would take advantage of the reduced gas waste at depth, but perform deco much the way we do now, on open circuit. >When diving trimix on open-circuit scuba, it is standard practice to use >nitrox(es) and oxygen for decompression, as getting off helium as soon >as possible gives a noticably reduced decompression duration. > >Running a few tables, it seems as this would also be a significant >advantage using a rebreather, ie do the main part of the dive on a >trimix (or heliox) diluent, then switch diluent for the decompression to >a nitrox. > >Are any of the (forthcoming) rebreathers capable of handling this?
