What solo cert do you have, has it ever been turned down?

Diving with a balanced rig is more important than redundant buoyancy.

 

[Subcooled]

This would be the opposite of the usual definitions.

I would respectfully disagree.

And I am curious. Do we define our words differently?

Redundant (means of achieving) buoyancy is very much different from redundant buoyancy compensator devices.
Buoyancy versus device.

Redundant means of achieving buoyancy are literrally just that. Any means of achieving buoyancy. How could anyone claim that dropping weights would not be a way of achieving neutral or positive buoyancy??? Redundant air bladders would be another thing.

Yes, we are using different languages.
Buoyancy is an upward forces. Dropping weights does not increase that upward force, it only stops working against it.
Inserting "means of achieving" completely changes what you are saying.
Redundant buoyancy is an adjective modifying an noun. The noun is buoyancy, an upward force. Redundant means more than one way of achieving that upward force, such as an SMB, or a drysuit, or dual bladders.
I think you are confusing buoyancy with movement upwards.

For redundant buoyancy I carry a backup BCD in the pocket of my BCD.

That’s kind of what I was imagining!

Dry suit failure is a specific problem but the redundancy there is addressed by default unless you’re diving w just a harness. I usually dive wetsuits these days so not so much to choose from.

How would you ensure this if diving a deep OC dive with three stages?

I have to agree with that. You're correct. When I talk about buoyancy, I am not thinking about physical forces but the net sum, which is more relevant to me. I could have chosen some other wording to avoid confusion

Yes. That's how I thought about it but I failed to write it out fully.

True

Your stages are not part of your balanced rig.
If you'd need to use the reserves of those, causing them to become very buoyant, you can always send them up on your smb line. (Or leave them on the cave ceiling and retrieve them on a next dive).

But since this is about diving solo, I don't think I'd do such a dive requiring 3 deco gasses. That's beyond my personal limits of what I consider acceptable.

Doing some OS mix dives using a bottom stage to extend the bottom time. Have to factor in the weight of the gas given that it could all be consumed in extremis. Being light at deco isn’t a good place to be.

 

[EFX]

Any diver must make sure he/she can return to the surface.

.....and stay on the surface.

 

[Subcooled]

.....and stay on the surface.

That's a very good point. Many have reached the surface only to sink again for the very last time. And this is true for buddy diving, too!
