Was meant for a Rebreather comparison
sheet, just comparing specs, features, options etc, side by side. Was hoping
to get some additional data, like weight and size without tanks/disassembled.
Nothing proprietary, still, bugger all from that lot.

Gotta say the best method to accomplish this is getting a few people dedicated to the pursuit to gather the necessary info (start with spec sheets supplied by the manufacturer and then go out to users) and then compile it. There will be some holes but people will chime in once they can see the comparison sheets.
Updating will be a bit more hassle as you'll have to answer two questions rather than one:
1. What new options are there?
2. Which old options need to be deleted or modified?
