how much lead?

scuba_phil · 16th December 2007, 22:09

Most of the replies so far seam to be on the light side - Am I doing somthing wrong?

Setup: 3L steel tanks, 5 lb SS back plate
Drysuit: TLS 350 with polartec 300 (5'6" 155 lbs, I sink in a pool)
Canister light: 2 lbs
Lead: 8 lbs on belt and 6 lbs up on the tanks (trim)
Total: 5 + 2 + 8 + 6 = 21 lbs
All air needs to be dumped out of the wing to submerge (min volume in dry suit)

My total weight is closer to the setup I use when diving with an single AL80

Comments?

That's about what I use. I also have a steel backplate and with steel 3 litre tanks.

Does it really matter? You will need to add weight until you are neutrally bouyant, somewhere between the surface and your planned depth of descent. Then, after you have managed to finally maintain your bouyancy throughout the dive without bouncing off the bottom like a yo-yo, and have done between 10 to 100 more dives on the unit, that will change. You will eventually use less weight than you are now...

The trick? ...Don't kill yourself in the meanwhile.

Similar config to Dive!Dive!

O3 RI suit

No lead (a pain for fresh water!)

You're not that far off, 21lbs = 9.5kg.
It sems other people run around 7-8kg. I also use about 20lbs but who's counting
