The title pretty much says it all.

While I'm sure the Stage Bungees I can buy from DIRZone are wonderful, I'm sure I can just grab an old inner tube and cut that to size instead.

Cut the tube on the diagonal and you can use pretty much any size you like.

I just used to use a bit of bicycle inner tube tied with a knot. The knot was really easy to grab when wearing gloves.

Nothing like making do with home made crap when you can buy the proper tool for the job
I've got an old BSAC manual that shows you how to make your own reel out of wood if you want the pattern ?

We're talking about a piece of rubber here, not home-modding a rebreather.

Same here, but I pass the tube through a practice golf ball even easier to grip the with gloves.

It's a state of mind

I've got an old BSAC manual that shows you how to make your own reel out of wood if you want the pattern ?So what, exactly, is the right tool for this job? I was one anal too, looked for, and found, the perfect bit of inner tube.

Then I saw sense and used bicycle inner tube. Worked better than the "correct" inner tube.

Or maybe I'm just not gullible and would like to spend my money on actual diving?

Can't you do both ?
Use the right kit and go diving ?

I have some suitable for an AL80 on the boat Stew, just shout next time you're down

Cheers Gary. Down next month. Might try and add a friday deep dive to the weekend.

I'm confused. As an adherent to an approach to diving which some would describe as overly-obsessive-compulsive about detail and "right" kit (DIR, in case it's not blatantly obvious!), I'm very happy with bike inner tube which does what it needs to (holds the hose against the cylinder), is easily available and, when knotted, allows easier stowing. The latter is particularly useful when handling multiple stages with cold-water gloves.

I'm unsure what's not "right" about this, but look forward to being educated, given my apparent strokery...

What do you think the design for stage bands came from? Think it might've been rings cut from inner tube that just about every cave and technical diver ever used? Just maybe?

Like most of these things, it's function not price tag. These things are tyre inner tube and if you can be bothered to find the right size or a size or any other solution that works for you then there is no problem.

If you can't be bothered / have something else going on that is competing for your time then there are shops that sell the inner tube of the correct sizes / sizes that have proven over time to work as intended.

I have found myself in both camps over the years.

what's wrong with 4mm bungey cord with a knot in it to form a circle with a diameter less than the cylinder size? pretty universal and adjustable. it seems to have worked for me for quite a number of years without me dieing from strokery.

It tends to roll when deploying/stowing. Inner tube tends to stay put.

Don't be so bloody stupid...









You need 5mm.... preferably pink

Depends how you tie it. I used to be all fancy and tie it with a nice fishermans hitch with the knot inline, bungee constantly roll off. Tie it with a big, fat overhand knot and it stays put a bit more. Plus it gives you a bit of a gap enough to get a finger under for stowing hoses.

That said, I prefer inner tube but do use bungee sometimes. Snoopy loops are too precious to waste. Like duct tape.

You could buy the same crappy tube from a specialist diving supplier and add 15 quid to the price tag and sleep at night. But as the saying goes, you can polish a turd...

A word of caution - the pattern has an error in it. I have a wooden reel that I made myself.

Bungy chord from a DIY store works just as well.... all this Tyre inner tube was just what they had available, not necessarily then only solution!

And there was me thinking some bright spark had the idea to join a load of loops together in a ring, fill it with air and hold tyres up with it. You learn something new every day :-)

I haven't found the error yet as I'm still looking through local skips to find the right wood, I'm thinking balsa for a light weight reel
Next from the book will be the compass with tobacco tin and cling film
I'm liking the kitchen knife in a bit of old garden hose that I have seen others with, maybe I'll go for that next

I got an inner tube today off a friend. It fits an 11L Ali perfectly.
The only markings it had is this
