    Hi, PastoDeco 4.9.0 dive decompression planner is now available. What's new: For rebreathers now it's possible to define a SAC multiplier for the first bailout gas. This takes into account the increased gas consumption in a emergency situation. The app calculates automatically, for the first...

    PastoDeco 4.8.0 update

    Hi, PastoDeco 4.8.0 is now available. What's new: * REBREATHERS: In previous version ( 4.7 ) is was already possible to determine max bottom time, with a given deco or bailout gas/tanks list. Now PastoDeco shows max TTS in normal CCR dive to not exceed to be able, in case of switch to...

    Mmm.... I dont figure out what kind of courses you made and what manual you have read that says that a END = 20 meters is dangerous or a PpO2 = 1.3 is crazy ...... ( and it appears, from your previous post, that you don't exactly know what a partial pressure is .... ). 25 minutes of additional...

    ICD and gas swaps

    The use of a 12/60 in a 100 meters dive is not in relation with ICD avoidance. PpN2 = 3 and PpO2 = 1.3 it's perfectly acceptable. The use of 1.6 as max deco PpO2 is a widely accepted procedure ( depending on training agencies ) PpO2 = 1.6 at bottom or at shallow depth still is 1.6. Pp it is a...

    Never seen 98ft narcosis. But if you want avoid it, yu're right. That said, Merry Christmas to all and have good bubbles.

    Yes, but even if you dont touch at oxygen percentage, you got similar results: Without decos: 10/60: Runtime = 791 minutes 10/85: Runtime = 1125 minutes With standard decos: 10/60: RunTime = 120 minutes 10/85: Runtime = 141 minutes

    I completely agree. Note that adding much more He than needed on back gas also increases total deco time. Just for example, if you calculate a 18 mins dive @100m/328f, without using decos ( just to see the impact of different mixes ), you have Using 12/60: Runtime 647 minutes Using 10/85...

    Standard or not, you must plan your dive and you need to check and label gasses after the blender checks. Now, if a gas is named 35/30 instead of 35/25 used at same depth, I do not mind.

    OK. I did not find it but if you say that it has EADD I trust you. On this point I do not understand your position ... Firstly, a hypoxic trimix diver is trained for using heavy tanks configuration that's a part of his skills. In the examples above, we've used the same number of tanks ... so...

    Yes I tried air, nitrox, normoxic trimix and hypoxic trimix dives. I think this is a deadlocked discussion. Yes, we all know that at certain depth, we all are, more or less, under narcosis. Question is: at which point? Does this affects our reactions and compromise our choices and our...

    ICD and gas swaps

    Yes I kwow that .... by the way I put in my software a EADD ( Equivalent Air Depth Density ) indication when choosing bottom gasses and deco gasses ( I think it's the only software with this option ). As conservatism ( Buhlmann w/GF's or VPM +xx factor ) everyone chooses what is best for him (...

    Everyone make it's own choices based on it's own experience and it's formation. And I agree that. I replied to a supposed additional risks taking care about ICD on gas switches because this require more tanks. This is not true and I explained with a rapid example. However I see that it has...

    ICD and gas swaps

    You have not specified if you use Buhlmann or VPM. Gas density ( EADD ) is 43m / 142f. What's the problem? pp = 1.6? This is normally used ... but in every deco planner you can adjust deco PpO2 as you want ..... ( however in deep stops you have a PpO2 = 1.6 for a very short time when switching...

    ICD and gas swaps

    This seems to be a Heliox dive instead of Trimix dive. You seems extremely conservative, using a END = 20 meters, which forces to make a big jump in END when switching on first deco gas: when switching on Tx 21/35 your PpN2 jumps from 0,33 to 2,95 instantly ( @ 190 feet ). ( PpN2 on orange...

    :) and what about of oxygen toxicity and narcosis ? it would be interesting to try to make a 300m / 984 feet air dive .... Stats are not your side.
