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)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 …
