^^ reasonable suggestions, but I have a couple of small adjustments to make
- if you do it in the pool then you may need to adjust the ballast (and therefore the lift) up by about 3-4% for salt water.
- the minimum lift to keep everything afloat might not feel comfortable. Remember you need to be able to float/swim comfortably on the surface too. The mimimun number might not be optimal.
A couple of things, one a wing will provide 2.5% more lift in salt water, because it's displacing higher density water. This won't cover all the additional weight you need in salt, but I suppose it will help somewhat.
We test our wings using fresh water........
If you do a buoyancy check with a full cylinder, you'll be light at the end of the dive. Tobin, you're not saying that proper weighting is eye-level with no gas in the wing and a full tank, are you?
Yes I read your post, and tried to respond politely. In my experience, if I start a dive neutral at the surface with a full tank, I'll be light at the end of the dive.
What are you using for a suit?
Tobin
Never more than a 5 mil, usually a 3 mil. As you mentioned there's not enough compression at 15ft to compensate for the 5lbs or so of gas used.
As noted in my prior posts I qualify my weighting suggestions with a very specific set of gear.
A thick suit will loose considerable buoyancy from the surface to 15 ft. This loss of buoyancy offsets the weight of the 6-8 lbs of gas in a typical single cylinder.
