[News] Herbert Nitsch Announces New No-Limits Attempts

[CEngelbrecht]

To what depth do you reckon is this dive?

Hard to tell, 30 meters perhaps. Like it says, it was the first attempt.

 

[jome]

To me it looked like a test-fire of an actual "rocket sled", a rigid balloon propelled by compressed air or maybe even some kind of chemical propellant, which takes of really dramatically. Or maybe my engineers mind is just reaching into fantasyland

 

[Simos]

It seems a lot deeper than that to me...

What I am a bit confused is that I had seen an early design that was actually produced that had automatic hydro-brakes for the last 50m of the ascend to reduce DCS and embolism risk, so I assumed Herbert wouldn't need to get out of the sled (at least not that deep) but maybe they came up with another design/sled since.. The sled on herbert's page and the video does look different..

Hi,

as far is i know Herbert always abandoned the sled at different depths because it was incredible fast - i don't think thats what they plan for the actual dive and they are just testing the speed of the sled at the moment. ( Thats what i get from the FB-staus updates from the guy building the Sled )

Found the very first video from August's trials for anyone interested (there was also a blog post from Trygons somewhere):

You can see the brakes in the first few seconds...

If it's the eqex again, i found something strange on that. Marcus Greatwood claims this on his wiki-page:

"Marcus designed and built the EqEx (Equalisation Extension tool) that allowed Herbert to equalise his ears deeper than 200m."

Marcus Greatwood - Wikipedia, the free encyclopedia

Herbert used 4 individual EqEx in Spetses in 2007, of 2 different designs.
The 1st design he used to 156m ( the PO.hf.EqEx),
it was to prove that the rigid bottle would work better than the balloon he used previously.

I did indeed use a Coke Bottle for the subsequent design (CC.hf.EqEx); with similar cap, mouthpiece and holder as the PO version.

 

[MIG]

On the video of Herbert's No Limits world record I think he stops using the bottle on the way down so must have reverted to some other form of equalisation. Can someone clarify that?
[/quote

That particular shot was taken on a practice/video dive to 40m.
Herbert used an EqEx that I hadn't finished building,
you can see the unsecured mouthpiece break away and air coming out just before the shot cuts.

Of all the dives that week, that was the shallowest and the one he nearly had problems
(having lost all his equalisation air and the brake not being particularly quick)

 

[Herbert]

Any word on what equalization method he's using?

If it's the eqex again, i found something strange on that. Marcus Greatwood claims this on his wiki-page:

Marcus Greatwood - Wikipedia, the free encyclopedia

This is the same guy to claim he's invented the mouthfill (http://forums.deeperblue.com/freedi...s/90774-very-deep-dives-without-mouthfil.html), so i'm having some doubts about this claim. Plus the eqex is basically a coca-cola bottle, the design of which is now almost 100 years old (Coca-Cola - Wikipedia, the free encyclopedia). Did he design the eqex before he was born?

Or has Herbert switched to wet equalization? That sled looks like it's very fast, maybe too fast even with an eqex for traditional air eq.

I am going to use an EQUEX (name given by Bill Strömberg).
Marcus "designed" the letters preceding the name EQUEX e.g: CC.hf.EqEx

More info soon

Cheers,
Herb

Great, Herbert is chiming in!

1) But I've no idea how to translate that "CC.hf.EqEx".

2) I would love to hear your personal voice over comment detailing the preparation and dive mixed into a cool video. Would there be an ROV company that's want to showcase their solution and try to capture your dive at depth?

3) How is your sled design going? How is your training going?
4) Are you getting some more sponsors?
5) Maybe a couple want to view you arrive at depth from a sub?
6) Perhabs sell the competition line meters, like Trubridge?

7) I'm happy to note that you're exploring new depths even without a possible challenger approaching your current WR.

8) How does your latest sled work?
9) What kind of safeties have you build in? With the things your planning the margins are growing slimmer ever more.

10) What computers are you going to use? Any change of a HR monitor recording of your HR?
11) With such a heavy sled, and long long line is it going to be exact enough? Or are you switching to steel cable?

A big load of questions, well we'll see what's get answered, thanks for taking the time to come over to DB and fuel our anticipation!

Love, Courage and Water,

Kars

technical term er okzzz

 

[Simos]

Yes 'technical' should have been in quotes :duh

 

[jay cluskey]

I think you mean terminology .
Easy mistake to make .... Like saying invented when you forgot you meant to say "developed"
Or saying coached when you were merely an adjutant
What ever next .. A book ? Rofl

It does stand for Hands Free Coke Cola Equalisation Extension tool.

Herbert you give me too much credit...
The Hands Free was one of your ideas...
You suggested tying the EqEx to the FP (fisting Part) of the Sled.

I put together the top of the bottle in such a way no air would get trapped in it,
Originally using a Palm Olive Bottle (PO.EqEx).

I also attached the tube (with a special ring to bite onto) to the top,
using a jubilee clip --- this was not fitted on the "video" dive....
I warned you it wasn't finished.


Good luck with the new attempt.

 

[jay cluskey]

roflroflrofl i was going to ask what the P.O one wasroflrofl

 

[Simos]

Palm Olive... Coca Cola... I can picture you guys walking into a corner shop in Spetses Marcus and asking in broken Greek what's the biggest plastic bottle they stock. rofl

Surely for 1000ft you'd need at least a Tesco 4 pint milk bottle. :friday

 

[ReefTroll]

Well, maybe with me being Australian I can become your new technology supplier.

 

[jay cluskey]

Simos you must use the technical term for the milk bottle rofl T4 L MB.H.F EQEX

[ame=http://youtu.be/2KGfBIdPD3M]800-foot World Record attempt June 2012 - YouTube[/ame]

The sled tests in Santorini were a success. The purpose was mainly to test the speed and directional stabillity going up. The sled was a prototype with limited functionality. E.g.: We did not install any speed control for the ascent. For that reason we could not start the sled above the water hanging from the boat, becasue of the risk of hitting the boat at 7m/s.
More test will follow in Austria after christmas.

What kind of depth did you take it to?

(cool video...)
