650m bounce planning

[Ruairidh]

Hey TDFers

I'm relatively new here, but having just about sorted out a new IDA hydreliox bereaver.

Was wondering if anyone knew a sensible and accessible source of space grade hydrogen?

I am planning on using a 75:20:5 (h,he,o2) to do a quick bounce down to 650m. Depending on how I feel, I will consider extending the dive to around the 700m mark. Does anyone know if padi or bsac offer a course specialising in the use of hydrox or hydreliox.

If anyone has any experience on this, or a similar unit, I would be very interested in hearing your opinions on good dives in the 500-600m range.

I am yet to come across a viable dive computer which specialises in hydrogen diving, but I have used a suunto zoop extensively. Given my experience with the zoop, I thought it best to use this, but am uncertain as to whether or not this will give an accurate decompression stop from this depth.

Thoughts?

Not sure that a zoop is really up to that type of diving. I would be looking at getting a Vytec they do multiple gases and would allow you to speed up your decompression

Alex Deas is your man.

Got tables for the Titanic.

You would not go far wrong there.

:nerd:

why bother with training. Just wing the deco on the fly

[gobfish1]

Just make sure you have a Bov and hud, also a 10L bailout cylinder ,
or Mark Chase will be on here wanting your home address ,

ps

Course specialising in the use of hydrox or hydreliox.
Think we have a top guru on this forum that will sort you some training and a 700m badge , all done on line for a small ish fee,

also
You get a free Aran Sweater with each Course you pay for

It was a crying shame he got sea sick sailing out to dive her, and had to cancel ,
then again we would have missed a thousand laugh,s on the internet , if he had gone a head :rofl::rofl:

He has no need to worry about Decompression, his computer is fine,

Make sure you do a course. Tel will be able to give you the exact progression you will need.

Can I volunteer to be a safety diver? I don't want to go too deep, so I'm thinking around the 2/300m mark (I have been that deep many times before, albeit in a submarine).

As I don't have a breeder, I'll use my normal kit, though do the TDF massive think I should maybe make up a twin-set if accepted as a safety number? Will I need to take my 'Spare Air'?

PS I'm still using an Aladin Air and/or a Suunto Favorit both from the 90s and they are just fine.

[Tewdric]

Remember to switch gas when you get to 70 bar or so, or your reg will start sucking air back.

15 and pony you'll be reet;)

Just do it on one of the new hydrogen snorkels

Even a bit of room for a Woodbine if it takes your fancy.

Remember to take some emergency oxygum

I cannot advise on rebreather units as I dive on open circuit.
Personally for diving below 300m I would suggest investing in 5mm gloves rather than 3mm. The neoprene can get a bit compressed so the 5mm keeps your hands a tad warmer.

You're talking bollocks and that can be dangerous on such a dive. Below 300m you want dry gloves even if you a diving in warm water as it gets cold down there. Don't forget you'll need extra torches as it gets darker as you get deeper.

Remember Richard Pyle - it's f**king cold!

Yes can do that easy, that sort of dive needs the Darkroom Course.

You progress to the point where you lie down in a darkened room until the whole idea goes sway :)

I watched that video while I was considering buying a CCR. Well funny. But he was in shorts and a shirt IIRC

[nigel hewitt]

Why the heck are you bothering with an IDA?
This is obviously a freedive.
Use 650m of line and rig it so the knot at the bottom pops the clip on the Blacksmith's Anvil you use as your descent weight and use a paraffin filled lift bag to pop you back up again.

[Ian@1904]

Remember Richard Pyle - it's f**king cold!I bet he never did a Rescue Diver course at Stoney in January. -5c air temp and +3c in the water, with 3mm gloves. I know what I am talking about....
Oh and I have dived in Icelend in +1c water in dry gloves. I just figured that dry gloves were over the top for a 650m dive

Don't be a tosser Gobfish







Any idiot knows he will need an AL80 as well :D

Panic over folks, I've got to the bottom of this (dreadful pun) but it was just a typo - should have read 650cm dive or was it mm, predictive text is a bugger sometimes:D

That would be oxygen rebreather territory.
He can't take the Woodbine in that case, all us divers
know oxygen is dangerous when smoking, not a nice
safe gas like hydrogen.

[Ian_6301]

Do fundies.

[Turbanator]

I'd bring the O2 down a nad's, I seem remember 4% being an bit explosive, or maybe that was 4% H and then some oxygen, I don't really remember, I was a bit narked when it did it.

An electrician I know was working in a house where the occupant was on medical oxygen. He smoked by pushing the (cold end) tip of the cigarette through one of the holes in the mask.

[Alex Denny]

I'm pretty sure Cousteau did a 650m dive with a 67:33 Hydrogen / Oxygen mix in a diving bell he used for decompression over red wine and cigars? The dive was a real blast...

Boom boom.

I'll get my coat.
