That seems low, I think ~25 lbs is more realistic with scrubber and a 2L o2 bottle. DR states 14 lbs with no sorb or cylinder. I’ll weigh mine next time …
Mine comes up to about 25 lb with the 5lb scrubber and an AL13 for O2. Add the smallest dil bottle you could imagine (AL6 or AL13) so as not to penalize for bailout you won't count for other units, and you're still at only 30 - 35 lb. The real answer is your total gear weight will be about 25 lb over what your total gear weight is with your OC config because there is really nothing else you will add or remove (unlike with most BM units where you actually replace most or all of your OC config with an entirely different setup for which the weight needs to be calculated)
 
Choptima is 78.5 pounds completely ready to dive.
That is including full 7l doubles, doubles regs, scrubber, wing, doubles regs, oxygen reg, scrubber, and a full oxygen bottle.
The rebreather is only 17 pounds of that.
It could obviously be much lighter with a different bailout setup, but this is how I dive it.

Triton's about 12kg ready to dive - but bear in mind that's the unit only with scubber and 1.5l O2.

Diluent/bailout, harness, etc is separate. I usually dive mine with my XDeep, so a single Alu80 as dil/bailout. If planning deco dives, I'll of course have more bailout. I also dive it with a BP&W, single 10l steel bottle as dil/bailout.

Nice thing about diving it sidemount - I can carry everything individually to the entry point and then clip it all on in the water.

For a typical dive that's not excessively deep, what's the standard configuration for a Chest-mount Optima?

Would a typical configuration be with *two* 7litre/50cf sidemount cylinders with a sidemount harness (e.g. XDeep Stealth). Assume one of the sidemount tins will be connected as diluent with the other as independent bailout/counterweight.

The ChOptima will be ~17lbs/8kg -- does that include scrubber and the Oxygen cylinder? What size is the oxygen cylinder?


Similarly @mwerle -- is that a typical Triton configuration?
 
I'm diving a P2 with 22lb lead to sink my cold water ins. Anyone know what a P2 is weighing with just unit tanks and regs?

I believe so. All the Triton divers I know dive it similarly. You can get a steel 2l O2 tank for it which makes it a bit heavier, but there's no on-board diluent solution for it (that I'm aware of). A mate of mine is playing around with a couple of small carbon fibre tanks he's looking to integrate into his sidemount harness for "short" dives instead of regular sidemount tanks.

Are you talking the Carbondive Worthington tank?

I don't know, I'll find out the details.

Yeah, same here (already told so). As you've stated, you can carry it bit by bit : a big plus for you and I it seems, but a big NO NO for some friends of mine who prefer a Revo or an Inspiration.
