Question Dry suit rebreather divers, how much lead?

[wetb4igetinthewater]

The thing is that people use a wide array of tanks on these units. Aluminum, Steel, 50cf, 13cf, etc. My CCR ready to dive (no lead) is 45lbs. A JJ with two LP50s is over 100lbs.

These considerations that you might want to ponder as you pick a unit.

I get that. My friend uses al80s for bailout

With a normal JJ in the sea I use between 2 and 7kg depending on the undersuit. A JJ with 3l steels weights about 38kg, slightly less than twin 12s. That is already quit a heavy thing. Using 7s or 8.5s instead makes it excessively heavy, at least for normal sized people, in my opinion.

You need to have a think about whether the bailout counts. Might you hand it off? Will it be positive when empty?

Mini tib + faber 3s, AL sides, CF200 + weezle, 24# in cold salt, 14# warm fresh.

3lb in 72F fresh water. Can probably go down to 2lbs as skills improve. Setup:

rEvo mini, titanium frame, 3L cylinders
Crushed neoprene Bare, custom fit - tight with little room for air
Mid-grade undergarments
72cf al bailout
Turtle fins - will be replaced w Deep Eddy's

Hi there, Santi dry suit, Kwark extreme undergarment, heat shirt, on T-REB sidemount eCCR with 1x80 cuft aluminium and 1x85 LP light steel, 3l steel diluent off-board and 1.5 l tank for suit inflation. Using 5 lbs weight.

Not being a sidemount reb user, but my 5 cents. Backmount KISS unit with 2l steel tanks, trilam drysuit, heating vest+ Subgear 490 undergarment (Large), rubber fins, lights, heater battery canister, and so on stuff. Dived mostly in cold waters (+4 - +8 deg.C)
for an hour typically. 6 kg of lead in reb case, 7 kg weight belt. Overall 13kg (sightly less than 30 lbs of lead).
BO not included (S80/7l steel/4l steel - according to dive site).

Meg (Tiburon)

Warm Salt Water (or minimal weight for beach diving, etc.)

Includes:
2L steel cylinders (charged)
Aluminum backplate
5 lbs of lead on upper backplate (for diving w/ a 5mm wetsuit)
Cave can w/5.5 lbs scrubber (full)
Small stainless steel stand (2-3 lbs)
Nerd, transmitters, BOV

Total: 73 lbs

Cold Salt Water

Includes:
3L steel cylinders (charged)
Stainless steel backplate
3 lbs of lead on upper backplate + 18 lb homemade lead v-weight (for diving trilam w/Arctic ug’s + Santi heated vest)
Cave can w/5.5 lbs scrubber (full)
Small stainless steel stand (2-3 lbs)
Nerd, transmitters, BOV
UWLD 160wh batt + light head + heat controller
AL6 inflation bottle + reg

Total: 110 lbs

(I remove 8 lbs from this for fresh water)
(I do not add or subtract lead when adding or reducing aluminum bailouts)

Not a Meg, but the JJ-CCR in all steel plate/cyls, plus custom shrink wrapped lead cylinder weights in the handle tubes, is basically neutral for cold drysuit diving at a land carry weight of ~40kg / 90 lbs
