    Helium prices ...

    Everything else being said, at some point the world will have to start considering helium a finite resource. That may mean higher prices, and for some this may mean to not use it for diving, or to switch to CCR. In Germany, Helium prices have always been very high compared e.g. to the US, so...

    Adding helium: some numbers to think about narcosis.

    I think to call it a "rule" is very hard to defend in light of actual data. As said, for several gases there seems to be an established correlation between lipid solubility and narcotic potential, but it is not established that this goes back to the actual working mechanism of the narcosis, and...

    Adding helium: some numbers to think about narcosis.

    Very interesting topic! I think it is however important to realise that while the Meyer-Overton-correlation is probably to good to be just coincidence, modern science does not consider lipid solubility as the one decisive factor in gas narcosis. It should thus be treated carefully I think. This...

    47 Meters Down: The Next Chapter

    Maybe the next movie in the series will then feature a tornado that lifts up people from land and deposits them in water where the sharks are waiting?

    Do you download your dive computer data?

    I would not have imagined this topic to be so divisive. My dive computer at least has a rechargeable battery.

    I treasure my logged dives :)

    Reported DCS on plane

    But surely before looking at reasons that may be behind outliers, one would have to exclude something that is definitely a substantial part of the probability box: DCS being diagnosed is not equal to DCS being present in this patient...

    Polish diver dies in world record attempt to 333m

    I do not doubt that it is allowed by the rules of this forum. I just do not think it is either appropriate at this stage, or useful. While it is true that many things that will be survivable at 30m are very lethal at 300m, as so often, the inverse conclusion is not true: not all things that are...

    Polish diver dies in world record attempt to 333m

    doctormike, I think it is trivial to see that there can be accidents happening during a record attempt that are not causally connected to the dive being a record attempt, or even very deep at all.

    Polish diver dies in world record attempt to 333m

    doctormike, I just think that if you want to criticise record attempts in general, it would be better to use a thread dedicated to that, and not one reporting a specific accident _where the cause is completely unknown at present_. The worst thing to do in accident analysis is always presuming...

    Polish diver dies in world record attempt to 333m

    doctormike, no one even knows what happened(!) Do you really think any criticism at this stage is useful?

    Polish diver dies in world record attempt to 333m

    "For the lst several hours we have learned that the good name of the late Sebastian is unreasonably attacked by people who do not have adequate diving knowledge and the basics of good manners and do not respect his previous achievements, which in recent years has brought much to Polish diving...

    Polish diver dies in world record attempt to 333m

    Well already 120m for the U-boat wreck is already quite deep.

    Polish diver dies in world record attempt to 333m

    Germie, many thanks for this detailed explanation! I had already tried to figure out the reason why CCR seems to become problematic at "shallower" depths than OC, and arrived at the CO2 problem. Very interesting to see it confirmed by someone who actually does challenging CCR dives!

    Reported DCS on plane

    I second the folks here that say that anxiety from thinking about DCS has to be considered as an alternative explanation.

    Care of latex seals - KY jelly ?

    Yes, I am just wondering why they would not sell in the US when proudly printing "Made in USA" and the Stars and Stripes onto the bottles. But, who knows, marketing...

    Care of latex seals - KY jelly ?

    It is McNetts, and bought online from a German dive shop. I see no immediate way how to find out when it was produced, the bottle is not dated. Basically all German dive shops still sell it, so I somewhat doubt that all this is old inventory.
