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.

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

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

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.

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

[Capt Morgan]

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.
