Do you think you can have a local discussion on radio or rv station. Perhaps in local language have translator, about the dangers of deep diving. I am halfway through my deco class now. Dive planning is mandatory
For recreational my ppO2 alarm is set to 1.4, what's the thought process behind 1.6 for this dive? Is it where the alarm is set but you monitor and stay well under?
A tec diver should not exceed 1.4 ppo2 on open circuit for the working portion of the dive. A 1.6 ppo2 is used during the decompression stage to maximize off gassing. The down side of using 1.6 is that you increase the rate of CNS buildup.
@@neilgarrett6271 what do you mean when you say "1.6 is used to maximize offgassing"? That doesnt make any sense. We use 1.6 only in our dive planner, to make sure we never reach that maximum amount, which would lead to oxygen toxicity. Of course we are never getting to that limit anyway. I mean the PPo2 of air at 45m is like 1.04 or something like that (off the top of my head), so it's just to make sure the planner gives us the right deco stages to eliminate possible dcs, without any CNS ect. You must of read somewhere that 1.4 is for rec and 1.6 is for tech I guess, but how you use those numbers for normal dives is to set your dive computer pp to 1.4 max, which is a conservative or contingency level.
@@DecoLounge-scuba No, @neilgarrett6271 is correct. You mentioned you are TDI, so your limits are 1.4 for bottom gas and 1.6 for deco gas. It is not true, you dot reach 1.6, because you used Ean50 for deco part. E.g. you switch at 21 meters, where the ppO2 is exactly 1.6 and that is the deco partial pressure, which opens oxygen window to accelerate the decompression.

Nice video man
Glad to see you back love the new format
When you say new format, which part do you mean?
@ more on diving than animals. I enjoy this more than
@@ivoryjohnson4662 that's because this is a separate channel than Critter hunter
It's a whole new world below 30m, very informative 👍
Come join!
Well done!
Thanks
Plan the dive and dive the plan !

Sadly, no one would care
@ that’s too bad , it’s tough after a recovery
Why do you even have backup computer... not just a depth and timer one?
Why would I buy a timer, if I have a training facility full of computers that can do same thing?
@@DecoLounge-scuba less wear and tear on more expensive equipment
@@arthur1670 I guess
Do you have good cave diving there? I just got my nsscds Cave Diver rating.
@@ryan021985 no not in Dauin

For recreational I'm set to 1.4 as well, but am pushing it a little more for tech

What was the purpose of that dive? All I saw was sand. Was it just to do a tech dive?
Yes. As I said in the video, I need to get more deco diving experience before moving on to next level.
@ Gotchya! I missed that part!
