Well, kind of proof that what was discussed here Why depth has an effect on sorb capability to scrub CO2 actually happens.

That's exactly what I was trying to praise to OP for (in my deleted post referring to a deleted post). At 14 we all made mistakes. Hats off to this young adult that, recognizing his, admitted it in public in search of (help, confort, support, guidance) you choose. He showed maturity and just...

Hello, definitely a good call. I am also for three strikes you’re out. and my check list is I’M SAFE Illness Medication Stress Alchool Fatigue Emotion. Your case either Stress or Emotion or both …! Stay safe.

Yes, I do that. Friend of mine was using spherasorb and got it in 10 lbs containers. Got a couple and I decant 2 fills for each container on a breezy day to get rid of dust and then I use those smaller containers (which you need to fill to the brim and then a bit more by shaking and tilting) in...

Excellent wreck I am going back probably weekend April 1st … happy to help somebody to dive it …. This was my dive 4 years ago. Sorry a bit shacky was a gopro 3 … Need to go back and run withe scooter on the main dack forward of the command bridge …

Do you have an SMB with 18kg of lift? That is 36-38 pounds: 18 liters or 5 gallons ....

Hello everybody, A little near miss (or two) which ended up with an aborted dive no consequences, but the thought process might provide points to ponder. Me and a frequent buddy meet at a lake location for a fairly deep dive. Plan is to follow a guideline starting at shore, follow it to a...

Diver is from Italy but Filfla is in the country of Malta non Italy …

feeling breathlessness at depth is no joke. I had a CO2 hit in OC and I know what it means. I really wanted to escape to surface as fast as possible and luckily I had no deco obligation, I was training … it took all of my will power to raise at a reasonable rate knowing the twin set on my back...

Yes but … Neutral at 3 ft with empty tanks … 4 and 5 only applies to open circuit: breathings changes nothing in closed circuit. I usually prefer to keep minimum gas in the suit …. and in the loop. I use BCD for buoyancy this because I can dump bcd and loop in any attitude while suit can only...

The way pressurisation works is: - high pressure air is taken from the engine compressor, cooled of in a heat exchanger (where it looses most of its humidity) and then sent to a mixing unit where it is reunited with hot air from compressor to achieve the right temp (outside temp can be as low as...

Do as I do …. fresh water dive after sea dive! :wink:

Just for the record, HUS is not made by APD. The company making the HUS hardware was bought by a big brand name entering in the CCR market and stopped selling the parts to APD. So APD stopped installing HUS to retrofit old units. Then APD recently sourced a different supplier for HUS and solved...

Ritrovato a Cala Luna il corpo del sub Paolo Sedda The feverish searches of firefighters, speleological corps, carabinieri and coast guard ended with the discovery of the corpse of the agent of the Nuoro Mobile Squad DORGALI. The body of Paolo Sedda, the 48-year-old diving expert from Gavoi...

Dramma a Cala Luna, sub disperso in una grotta marina profonda 40 metri - Casteddu On line Drama in the Sardinian waters of Cala Luna, we have lost track of a diver who dived with a friend. The request for SOS, received at the operations room of the Nuoro Fire Brigade Command, by the Port...

Sub disperso a Cala Luna, riprese le ricerche all'alba - Sardegna At the first light of dawn, the search for the diver who was missing yesterday in a cave in front of the beach of Cala Luna in Dorgali resumed. This is Paolo Sedda, 48 years old from Gavoi, an agent of the Nuoro Police...

depends a day old baloon stops floating due to the fact that helium escapes … being so thin, and in a mix this would be even less apparent helium would effuse faster than nitrogen and oxygen ….

... aRe you sure the temperature of the gas was equal or the subsequent baloons might have been filled with colder gas (due to the cooling from expansion) and therefore denser gas .... just saying that there are more factors to consider. Gas Diffusion and Effusion | Introduction to Chemistry...

Gas switching is the most stressful moment of the dive. The more complicated you make it the most dangerous and prone to error becomes. Additionally for the slow tissues which are under perfused I don’t think that the progressive switching illustrated above would allow enough time to offgas...

Disclaimer: I am not a deco guru so my opinion is worth what you paid for it - Nothing and do not blame me if you get bent. Once that out of the way ... The issue with IBCD is that the different solubility and speed allow the sum of the gas partial pressure to exceed the tissue maximum...
