Does a scooter count as 'redundant buoyancy'?

[Nick_Radov]

You're asking the wrong question. Redundant buoyancy isn't required, so whether you need a drysuit or scooter or something else for redundant buoyancy is kind of moot. What you actually need is a balanced rig, and it seems like you're at least close to having that. Although for tech diving in a wetsuit I would lose the tail weight and go with a regular weight belt that can be ditched in an emergency if you have a buoyancy failure at the beginning of the dive, when you're still carrying significant gas weight and haven't built up a major deco obligation.

That said, it's a good idea to carry an extra lift bag in order to give the team more options.

Well, with a scooter as redundant buoyancy, a spare air as redundant breathing supply, and split fins as redundant propulsion, I have only 3 words.

You’re gonna die.

I suspect using a scooter to hold deco stops for an hour or more might not be sustainable, if you're doing drift deco.

you'd be on an SMB by that stage would you not?

well he is very much alive at the moment… seriously though ; i do agreed on the spare air ; but given the scenario he described i don’t even see any issues with split fins.. somewhat protected water, no current do not call for wood planks. on the scoot as backup boyancy what is the issue that you foresee?

It’s a joke, Son

That instructor seems like a bit of a tit.

You’ve two SMBs and your scooter.
Plus there’s other options as you mentioned, such as dumping backgas.

Plenty of buoyancy and you’ve thought about the options.

I understand this view, however adding a weight belt when I'm already carrying doubles and 3 deco tanks and am already extremely negatively buoyant at the start of the dive just doesn't sit right with me. After feedback in this thread, I'm going to be adding a lift bag to my gear, in my left short pocket with the rest of the 'emergency' gear (spare mask + spare reel).

I think you misunderstood my comment. I didn't suggest adding a weight belt to make yourself more negatively buoyant. I suggested replacing some non-ditchable weight with ditchable weight (on a belt or elsewhere) when tech diving in wetsuit so that you can establish positive buoyancy in case of a wing failure at the beginning of a dive. The stages don't really count because you can also get rid of those if necessary.

tell me , what is the diving location?!
