Petrel Tissues Demo

[@hitchjay]

I was having difficulty understanding GF for decompression theory and this visualization was perfect... Thank you so much

[@ShearwaterResearch]

Hi Cathal, you can see the tissues bars at any time by pressing the right button a few times to scroll through the various info displays. The purpose of the display is to inform and educate. For instance, on the surface you can see how much residual inert gas remains after a surface interval. At the end of your bottom time, it might be interesting to see which compartments have saturated. The info isn't incredibly useful, but it does give some insight into how the deco models work.

excellent video. Certainly highlights one of many useful teaching features on the Petrel for those of us who instruct. And of course, yet another reason to invest in a Shearwater.

[@alexhoksbergen6161]

This is a very clear and well explained demo, thank you, I learned a few things about my Petrel today!

[@ShearwaterResearch]

Yes, if we get feedback that it will be a useful feature, then we'll add it to the next Predator update.

Hi. Great video, thanks. Just purchased a PERDIX Computer. The manual directed to this and other videos. Getting used to. Going to dive this weekend. Can´t wait to go in with this great Computer. Regards

[@richardtomlinson4425]

Thank you - just bought a Perdix AI and this is very helpful.

“WHAT HE SAID”

[@bcdiverdennis]

Great video ! Well presented and clearly explains what's happening.

[@barryshively6938]

Look forward to seeing the bar graph in a future update

[@cfr94363]

Great video, you made it really easy to understand what's going on. Thanks!

[@martincalleja]

Hi, great tutorial. you nailed it. They say that curiosity killed the cat but in this case, it made him more aware! thanks.

[@cam2724]

THIS IS EXCELLENT!!!...very good tool for explaining how Tissue tensions work.

[@pai5000]

Excellent online visualisation of the GF. Looking forward to get this on Predator as well. Thank you.

[@pathfinderLXXIV]

Any chance of a firmware update where you could change your inspired surface gas? So, if you're on the surface and breathing 100% O2 during your surface interval, it'll account for that?

[@brian6140]

very interesting and enlightening. I have to confess I rarely watch that graph.

[@brazeagle]

Very nicely explained. VALUABLE info. Thanks a lot.

[@zgoume]

Very nice video! I've just bought the Perdix, and i was kind of confused with this graph! Now it's clear!!

[@diveaddict6885]

Great explanation

[@ygr2110]

Thank you, very helpful and well done 👍🏻

[@daneapeterson]

Well done Sir. Excellent and informative video. I am now a subscriber.

[@SEA-O2]

Do we have transmittable ccr o2/co2 sensor readings yet? Do we have CCR loop gas analysis checking mid-flight yet? Do we have CCR, full-purge and no-purge, loop flush with gas-switching on the fly yet?

[@SylvesterMuller]

Cool, will that be on a future update for the Predator?

[@andyaston]

At last I understand GF thanks, I was just wondering if the inert gas would be comming out quicker at 10ft as opposed to 20ft as there is a bigger pressure difference or is off gassing linear? I would of thought the bigger the pressure difference the faster the gas comes out of a solution. Or is the model based on it being linear?

[@RichardWait]

Thanks for the info. Very informative. Now....do I wait for the Fisher Petrel or go and get a Predator! Hmmm

[@Bozacar]

Why M value is not calculated based on partial pressure?

[@keratoconus2821]

good job sir - shame on the thumbs down!

[@tomthompson7400]

I read in the updates for predator that tissue graph was added , I upgraded my 2016 predator , and didnt see the option for tissues , or is it only visible in dive mode .

[@mrtomaszgorecki]

Thanks for video, I found it very helpful. In the end of film I understood that computer will be useful also to observe off gassing in the surface and I’m interested - can it help me to monitor when can I go trekking on mountains after dive? Is it taking into consideration decreasing pleasure on the surface when I’m going up?

[@mrtomaszgorecki]

I was thinking about decreasing pressure when I'm going up :-)

[@felixmatthewcheryl]

do you have a video showing the Petrel EXT model. I am an SCR diver and has a 3 cell O2 monitoring system and would like to see how this works. Thanks

[@guilhermeaguiar9498]

Congratulations!!!! Very nice explanation!!!!

[@jamesrankin1041]

Excellent video!

[@turbo13r]

Hi Bruce Can you outline how this tissue data is utilised by the diver i.e. are we supposed to have this tissue screen on display throughout the dive, or is it for reviewing the dive afterwards and if so how do we access it?? Rgds Cathal ( new petrel owner)

[@tombodera3338]

Thanks. While on the surface you mentioned that the computer assumes you are on air, but the ppo2 displays 0.99p02. Should it not be 0.21 p02?

[@qilu6313]

Nice video! This should also apply to Teric right?

[@ShearwaterResearch]

Yes, it does apply to the Teric too.

[@albertokusmic9239]

Very well explained, thanks!

[@josemanuelcarvalho6413]

great video!! really helped! thanks.

[@christinababcock305]

How did you get the tissues graph to "stick"? mine keeps defaulting to the main screen.

[@robertbutcher1822]

Thank you very clear

[@lucasmacmillanhernandez1965]

thank you !

[@hummaid1]

Switch gas during deco stop will increase eliminate nitrogen from tissues . Is it factor to form bubbles in blod stream?

[@makismakis9955]

nice video.

[@peterbucknell]

good stuff

[@sergiomartinezherrera6076]

Thanks for making clear that know nothing about diving..😂
