Drysuit weighting doesn't really come from your body weight — it's
the suit material and your undergarment, and it's the one setup a
calculator can't pin down. A shell (trilaminate) suit has almost no
float of its own; with light undergarments you'll often start near
your equivalent wetsuit number. A neoprene drysuit floats a lot more
on its own — figure roughly 7–10 lb on top of that. Heavy
undergarments add more again. Start there, weight-check carefully over
your first few dives, and drop lead as you get the suit dialed.
This is a number to rig up with — then let the water correct you. Do a
real weight check on your first dive and trust that over any calculator,
this one included.
The weight check. A real weight check beats any
estimate. At the surface, holding a normal breath with an empty BCD,
you should float at eye level and sink slowly as you exhale. Adjust
from there.
If you're newer or getting back in. You'll probably
sit toward the top of this range at first — a little heavy while you
find your trim. That's normal, and it's the safe way round: easier to
get down, and you pull the extra off at your weight check as you settle.
