^This and also fly below 10,000’ and keep max differential pressure to 0’ cabin altitude … quick descent if loosing cabin pressure becomes an option.

Does lifting your kit from the cave back to the trail with some heavy lifting and walking counts as work out … because then I would have to stay overnight 😁 Sorry but many forget about non boat dive where you are the diver and the mule that carries the stuff and for some dives there is a bit of...

Any good reading about the issue available on the net? I’d like to understand better … I mostly have experience in protecting outboard engine in salt water or stainless pipes undergroud (cathodic electrical protection). Thanks

Sure about that? I thought that, in order to protect aluminium, you would need a less noble (more electropositive) metal to be corroded like zinc (sacrificial anode). Why would the aluminium strip corrode and not the aluminium of the tank? Unless you are talking about protecting a steel tank, in...

Excellent decision … you just avoided the sunk cost fallacy: The sunk cost fallacy is a psychological barrier that ties people to unsuccessful endeavors simply because they've committed resources to it. Or in layman terms did not throw good money after the bad: thinks the expenses and the...

Rather than a second BOB was needed for deco. Liberty has a radial 2.5 kg scrubber and it wont be able to do the 12 hours needed. So you dive with 2 and the bob in case of failure allows you to get to the deco reb. You’ll need at least 2 reb to do the dive. One is spare.

Sad news. Plan to descend half way to the wreck. Deep diving on air. Twice the alcool legal driving limit. Getting distracted …. Looks like the diving in the blue hole in Egypt famous place diving there to say I have been there. Some do not come back. Nothing said about deco plan surface...

I would definitely advice against diving with a single source of gas. If you lose the onboard diluent for a blown whip or a free flow overpressure valve or second stage, you would lose also buoyancy (dry suit or bcd and diluent). So for your sake have a second bottle or at least a dry suit...

Around here you need to have a prescription for medical oxygen. But my supplier told me he fills all bottles from the same LOX tank then according to the intended use bottles and paperwork (and pricing) differs. I asked him if he would supply me with industrial/welding filled in bottles in which...

My first tank a steel 232 bar 18 liters is a G3/4 tank. Bought in 1984 and still going strong and in excellent internal conditions. I had to replace the valve and it was hell to find one. I ended up buying a used one from a scrapped tank …. maintained to new and installed. Be careful out there...

Better be able to run it manually … should you ran out of battery power for the computer!

In diving (and aviation for the matter) when everything goes well you are far enough from the limits of technical capability of the equipment and well within the ability of the operator to feel overly safe. When the proverbial hits the fan …. well the respiratory (and cardiac) rate goes up, gas...

don't forget depth. the whole thread hinged on that ….

I saw the video of the testing circuit. Moisture heat and co2 where added to simulate respiration but, if I recall correctly no bio goo. Also consider that those should be trapped by the expiration counter lung and not end up in the canister.

exactly, we would be a great team :wink: I was typing while you posted the link!

I regularly reuse scrubber. There has been a study published and presented at EuroTek 2016 (@Dr Simon Mitchell and all) showing how a air sealed scrubber in a month time has little f no degradation in CO2 absoption. I do not have the link available. It was widely disseminated. Next day use is...

Also APD for inspiration vision 2020 has multiple color combination and you can even choose and pick colors and design your own screen.

CO2 is kind of insidious. It creeps on you and when you are hit it is difficult to get out of it. I will be forever grateful to my instructor when OC made me overexert and the only time I have got a CO2 hit was in traing and OC. It is bad, I was at 10 meters and overexerting with a twin set and...

Hello Beester, the problem here is that the reaction front deepens with increased gas density and efficiency lowers. So the scrubber is not able to keep up with: -increased flow; -increased rate of production of CO2 Lowering them makes a scrubber able to cope but you are endangering yourself. I...

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