Most certainly not - I may not be the biggest fan for the third worshiphouse of Irvine, but this I think everyone will admit is bloody impressive (also I'm bored and nothing has been posted here for 10 days....)


The EKPP (European Karst Plain Project) pushed the Doux de Coly on August, 22 to 5675 mtr (18618 ft) distance to air.

The dive started in the morning of August,22 at 7:03 am and lasted 18 hours 21 minutes. The divers Michael Waldbrenner and Reinhard Buchaly surfaced in the morning of August, 23 at 1:24 am. 675 meters of line were added and surveyed from their 5000 mtr endpoint of the last year.

Both divers used a double RB80 rebreather configuraton with 2x 20 liter backmounted bailout cylinders (trimix 16/80). Three drive stages were used with 2x trimix 22/70 and 1x 16/80 and five magnum Gavin scooters per
diver. All rebreathers were fitted with a custom counterlung optimized for the depth of the cave. Lighting was with a 18 Watt HID with a custom made reflector powered by 20 Ah Nicads.

The dive started with a visibility of 15 to 20 meters ( 50-65 ft). Due to heavy rainfalls two days ago the vis reduced after approx. 1000 m (3300 ft) distance to initally 4 meters (13 ft) , then 2 meters ( 6 ft) visibility. Luckily the vis improved again after 2300 meters (7500 ft) to the starting vis.

Again at 4500 mtr (14700 ft) the vis went down, but it improved after further 200 meters. When reaching the endpoint of the last year at 5000 meters (16400 ft) it was expected that the cave would continue the downslope. But it stayed at a level between 65 and 60 meters (213 - 197 ft). The cave got smaller at 5300 meters (17400 ft) where the tunnel ended in a T. Choosing the way to the right, the now smaller and silty tunnel went in eastern direction til the line was tied off at 5675 mtr.

Bottom time was around 8 hours. The decompression took place in the shaft 300 meters from the entrance. Total deco time was about 9 hours 15 minutes. Additional time was spent travelling the shallow part and entering and
exiting the habitat for the last three hours of deco. Water temp is around 12,5° C. Both divers felt well after the dive, and after a good sleep jogging the next morning showed no lung problems.

A more detailed description of the dive and the team effort will be placed on a website in a few weeks.

We want to thank our great DIR support team for their excellent work.

We had a lot of fun within the team and enjoyed the dives.

Reinhard Buchaly and Michael Waldbrenner


Found on a DIR-lovers site http://www.innerrealm.co.nz/ - even has GI's definition of a stroke and his reasoning against the Expiration (YBOD)

Bugger it, I'll quote in BOLD ITALICS

The Doux De Coly push isn't a fantastic achievement - there are many British Cave Divers who have achieved more monumental pushes using far less equipment.


I only called it a fantastic achievement for the fact they could carry 5 Gavin's, 2 RB80's with 20l bailouts, three stages and an 18W HID with 20Ah powerpack - imagine the size of wing needed!

:lol:

and his deco theory is equallyl respectable.


Like ferk is it - it's taken a real battering recently on DiveOz (Strokes Vs DIR forum) by many including Dr. Simon Mitchell, hyperbaric specialist who was one of two divers on the HMAS Centaur wreck at 175m......

And I quote....


Hi everyone,

I've only just picked up on this thread and I know the first page stuff is a bit out of context now. However, (and let me wipe the final tears of laughter out of my eyes)....

Brad, how on God's earth can you give any credibility to someone with no medical training, who would argue with a specialist diving physician about a safe layoff from diving following decompression illness?? Don't bother answering... it's obviously a rhetorical question.

Oh yes, and just to endorse the point made in the initial post. Let's hear no more rubbish about how George's theories are proven by his safety record. You have not got a foggy clue about the incidence of DCI in dives conducted according to "George's theories", but clearly there is an incidence (and I suspect we will never hear the truth of it).



taken from this thread . Also see the bitchfight "Innerrealm" (who's site the DDC Push was from) gets in with everyone and gets shown up for the usual "scrape and regurgitate" tripe. PS Please bear with it as it's a 6 page thread but 3-4 is really funny and it gets better.

For GI's horizontal arguement (a.k.a hydrostatic head problem) see Here (and 'scuse the start - my usualy bitchfight over steel verses ali wind-up... and also Here from which I quote


Finally, and with respect to the criticism of Kevin's form, if any DIR diver can produce ONE set of valid DATA describing an outcome advantaqe for "horizontal" over "vertical" decompression I will personally consume a turd from the DIR diver of their choice in a bread roll.


By Dr. Simon Mitchell (again)

For a real laugh see Gunning down Richard Taylor and Simon Mitchell   for the poor side of DIR mentality

PS 'scuse the post - Jay, what's going on with the "quote" thingy? It's shot tae buggery - edited

Look closer - 4th line should end that level and return to normal but does not and don't blame me - I clicked "quote" ;)

Auto-dump? Pah! That's cheating - you can do it with a cuff dump but means coordinating breathing for bouyancy control with raising your arm and dumping.....

Wibble! :wierdo:
