When I'm diving with my drysuit I wear a SS B/P with my PST HP 120 tank. This give me all the weight I need to dive comfortably.
Wow! What are you...a stick?
I am jealous! I need tons of weight to get down, especially in my drysuit, although I don't have a lot of experience in it yet (1 season) so hopefully I will drop some.
How much garment are you wearing with this? That gear in itself constitutes a fair amount of non ditchable weight.
Regarding Jim Baldwin's weighting configuration...
He's got 6 lbs. (SS BP) + 2 lbs. (empty PST120) + 2 lbs. (reg) = 10 lbs. total ballast.
Assuming that he's properly weighted, either he's got a trilam or bilam drysuit with little or no undergarment or he's got a somewhat negatively buoyant drysuit + medium-weight undergarments. Then there's the issue of whether he's diving in fresh or salt water (with fresh water requiring approx. 5-8 lbs. less lead).
The other possibility is that he actually has one of those Heiser HP120 tanks which is 18 lbs. negatively buoyant when empty.
If this is the case, then that makes his drysuit + undergarment have a positive buoyancy of approx. 26 lbs. (6 + 18 + 2)
However, when I'm teaching and using my HP 100's I wear a weight belt. I use the plastic tri-glides and have four pounds per side positioned exactly where I need them. The weights don't move. Used this setup for years without any problems. The tri-glides go in the middle of the weight if you are using flat weights like in the pictures above not on the ends.
When you look at his weight configuration with a HP100...
His total ballast is: 6 lbs. (SS BP) + approx. 2 lbs. (empty HP100) + 8 lbs. lead weight belt + 2 lbs. (reg) = approx. 18 lbs. ballast
Assuming that he's properly weighted, his drysuit + undergarment now have approx. 18 lbs. positive buoyancy. Sounds a lot more reasonable, but there's still a significant discrepancy compared to when he's using the HP120 tank. Weird.
I suspect that some info is inaccurate regarding his weighting configuration with the HP120.
Or, I could have mixed up my numbers somewhere...
