Hey Pete, not me! My renewal was billed 25 March, but I have lost my red status. Need to look into that paypal connector :wink:

Hello everybody, this incident will become a learning experience for the whole diving community thanks to Mrs Bugge. Those who might be interested may want to follow this documentary which will be released on the second anniversary of this tragic event. I wish to thank Ashley, a fellow diver...

Tursiops you ask: Immediately after postin a file containing the deltaM values for all compartments for several deco models I say that you just did it And you scold me to be more rhetorical than you did? Kettle and pot come to mind but I am not a native speaker and some subleties of your...

A table with all deltaM values (they differ by tissue) is in the referenced file you posted above: Table 1 Just saying.:wink:

In order to understand this think to the blood as a conveyor belt. It picks up oxygen at the lungs and brings it all around the body. If oxygen is needed it is used by the cells, if not it stays on the conveyor belt. When the coveyor belt goes back thru the lungs, if there is space available on...

Late to the thread but most of the times the flow at the orifice is sonic, (pressure in the tank at least twice than ambient) so the flow is constant is the density changing. That happens linearly with pressure ... also T=m (v1- v2) T=trust m=massic flow wich is rho*s*v1 rho is density s...

Exactly, and that is the reason why I dump from the nose. It clears my mask if needed, it is dumping used gas it does not require to use hands and it is done instinctively. Concerning dump valve, mileage varies. My unit, for example, has two: one for each counterlung so I can choose (provided I...

Hello there, while many reb diver use boosters, I suggest a better audience for you question might be in the boosters and compressors forum> Compressors, Boosters and Blending Systems

Actually joint cavitation can happen even if not diving. But if you have been diving then rather than filling with synovial fluid at the end of the mechanical cause creating the cavity it fill with gas coming out of the synovial fluid itself and not going back in. Cheers

Physical activity can create depression due to cavitation in moving joints, these might attract gas that would otherwise be carried out (albeit more slowly due to the low perfusion of the cartilage in the joints) by the blood stream. Once in gaseous state it becomes difficult to remove the...

Understood. I dove a vision with the old LCD display and upgraded my unit to the 2020. And also once sone with MOD1 and put 50 hours on the unit I moved to a PLDT frame. What I am saying is that you have 2 independent controller since the classic which had them in the pendants, when moved to...

Monochrome display has Vision: two controllers two batteries and keeps working after the display dies. you know ppO2 by HUD ... Maybe your try dive was too quick :wink: and did not explain the unit.

I am puzzled. All the APD rebreathers I know have double controllers. The classic had double pendant also (controller was in there) while the subsequent models (vision) had them in the head, with a single display input unit. Which unit are you talking about?

Or,more appropriately, yellow box of debt!

Apparently crushed to death by a steel sea-line (maybe a different word for pipeline) while in saturation. The news bit says it was already beyond hope once in the hyperbaric chamber on board of the support vessel. Travolto negli abissi dell'Angola: muore al lavoro subacqueo di 42 anni

According to a couple of source on Facebook and online he might have contracted melioidosis: Melioidosis | CDC Here is the CTV News report from yesterday about the Navy Seal possibly contracting Melioidosis: CTV National News: Thai Navy Seal dies

^^ What he says. You are using imperial so I did have to convert: 150' is 45 mt so 5.5 bar so the max FO2 to have 1.4 on the bottom is 25%. So filling EAN28 and then topping off with air will give you - even starting with 100 bar (1500 PSI) - a good Nitrox (EAN25) for the second dive. Less...

A superior diver uses is superior judgement in order to avoid using his superior skills. In order to build superior judgement we need mistakes (own or others’). Thank you for posting yours. I believe this time you had to use your superior skills ... well done!

Why not. I had one with 10 charges in the pocket of my g-suit for years It has as many flying hours as my helmet has! Sorry I could not resist!
