Drysuit and squeeze question

[NW Dive Dawg]

There's a lot of variables, the amount of air you started of with, the cut of the suit, the material it's made of, the depth of the dive....

I totally agree and this is exactly what I have been saying.

Your body has nothing to do with the stiffness of the vacuumed suit, the air in the suit is the thing getting compressed and the resulting vacuum is the force keeping the suit stiff.
There's a lot of variables, the amount of air you started of with, the cut of the suit, the material it's made of, the depth of the dive.... But no matter the variables it's a thing that has happened to people. You have first hand accounts of people getting bruised in this thread and a reported fatality.

Simultanteously. Not having the suit hooked up, doesn't mean "instant death"

You're not going to get crushed to death by having the suit not hooked up, you might loose mobility have a hard time breathing but you're not going to get imploded.

OK, those of you who dive in a drysuit...

How many people have NEVER jumped in without connecting their drysuit inflation hose at some time in the past?

I jumped in yesterday and in the process of hitting the inflator the first time it popped off by accident with my dry glove ring...

I've never JUMPED in, but I've walked in.....

Your body will always experience the current water pressure, the difference is friction - fabric has almost infinitely more friction than air. Try this this standing in your garage in a drysuit;

• Have someone walk around you applying clamps to all the slack material.
• Try to move - impossible despite not having the extra pressure pressing the fabric against your body.
• Inflate the drysuit to expand the clamps (assume they don't fall over and keep applying pressure)
• Try to move - no problem as the air gap eliminates friction.
