Trust me, my intention wasn't to debate but just to clarify.
As others have pointed out, the Vision deco uses GF algorithm. So if you want to have a back up computer using the same algorithm, there are/will be only 2 options:
- Shearwater
- Heliox
AFAIK, the status of the aforementioned are:
- Shearwater new hardware/software is complete and Bruce is waiting for the case. Bruce will have different options for connecting to the sensor, or to replace the existing displays depending on the unit.
- Heliox is also waiting for the case.
Of course, no one knows but I think both will be ready about the same timeframe (this Spring). Contact them directly for additional information...
If you want similar profiles, use one of the computers with RGBM or VPM algorithms such as:
- VR-3 with VPM/B option
- HS Explorer (with RGBM)
or one that (supposedly) produces deep-stop profile such as:
- Cochran EMC-20H
Hammerhead uses GF algorithm, but you can't have it as an independent computer.
However, doing deco dives on a CCR requires more than just a redundant deco computer since you will also need to plan for adequate OC-bail-out. So most people also carry a back-up table with the OC-bail-out requirement computed as the last source back-up.
