When I was young and dumb, I jumped to point out why those who perished had broken some rule that I never would. I will never forget how Jean wailed around the campfire the night we learned that Marson had passed. She expressed emotions with those actions that reverbrate in my soul with every...

Hi Blake, I've sent the update to Apple to review, usually takes 24 hours then it will be available for update. I fixed both issues. Like I mentioned, the item 12/16 issue was caused by an incorrect variable name; I had copied the code for earlier lines and edited a unique variable number, this...

Thank you for the feedback!! I will work on updating both of those issues, I can’t promise on an exact date for the fix but I will try to get it out before next weekend. The item 12/15 issue is definitely just a typo on the variable name, and the rounding is caused by me selecting the wrong...

@CWC I caught a bug this weekend that slipped through my original testing, which caused the fourth gas to not get selected properly...and while I fixed that, I managed to slip in a basic gear service-by-date tracker. The updated version is available today, looking forward to your feedback so I...

Just ahead of Christmas, new update released! Checklist now shows END in feet or meters based on your settings Fixed checklist bug that prevented certain "display/not display" preferences from saving Streamlined the checklist gas input, removing the PSI entry and replacing with a simple full...

Thank you SleepySlipper! Believe it or not...there is no autocorrect for text inputs in the Xcode application where this is created. It's easy enough to test for output of mathematical functions to be correct based on an input value...and in general, I develop text in another app which does have...

New update being pushed out now, addresses some of the feedback received so far. Now, in settings you can set whether you want to track 3, 4, 5 or 6 cells. When adding the cells installation date and o2/air mv readings at install, you can also select to see additional details and store the...

Thanks for the honest feedback azstinger11! Even if you decide not to go back to the app, I'd really appreciate some more nuanced feedback, which you can share here, or by message, and I'll see what I can do to make updates accordingly. I guarantee there are others who had the same thought but...

I can't speak to that unit, but I use LP27 for onboard o2 and dil on my optima. It's extra gas without any extra real bulk. The unit is basically the same size either way, though it does make the unit a tiny bit taller, that's fine, it's still shorter than doubles. The advantage is: -More...

I mentioned this app in a recent thread about rebreather diving checklists, but that thread was about checklists in general and sharing updates there would have been off topic. This week I've rolled up an update that adds support for capture Shearwater cell mv readings from the camera, updates...

Before I was even finished with training on my unit, I had started formulating an updated checklist. The stock checklist included the build instructions, so it was long and included many steps that are not only obvious, but if done incorrectly, would be caught by a later checklist point. My...

NSS-CDS minimum starting gas volume is 40cuft for cavern diving, or 75cuft for cave diving. 75cuft in an al80 is 2,895psi...of course, they clearly violated multiple rules, but I hadn't seen this one called out. I remember Rich Courtney making us do the math between each dive to confirm we had...

I recently purchased 2 S bottles of helium from different sources. Turns out, both were empty, despite one being claimed as "partway" full and the other supposedly full, full. One of them did have a wasp nest in the cylinder cap, which I discovered while driving on the highway when they...

Isn't the reason we carry bailout, so that in an emergency, we can ditch our non CE rebreathers to avoid any legal or insurance issues? In the ocean, it'll float away, especially with a carbon fiber tank. In a cave, you may have to push it into a crack or camouflage the unit, but the Choptima is...

What part of the servicing do you not feel comfortable doing without the service manual on hand? If you have specific questions about things like torque, maybe someone here can provide those details for you.

I don't know if it's fair to say that tracking linearity from 0 to 1 is completely irrelevant. Is it fairer to state that a cell which is not linear from 0 to 1 is not going to be linear from 1 to 1.6, but that also, a cell which is linear from 0 to 1 is not gauranteed to be linear from 1 to...

John, I have one that may also be inoperable. It started giving me co readings on pure o2, and I stopped trusting it. It is possible it is a sensor issue or something that is repairable. If you think it would be helpful for you, I'm glad to mail it to you for free. If not, then no worries.

Tom, thanks for sharing your kinder words in reply to my concerns. Really appreciate hearing from Andrew's closer friends, as well. Bob, good to hear from you too, sorry to hear you aren't cave diving anymore. Since I had a kid last year, my own diving has been reduced. I feel like a...

Tbone1004, I've been searching for the most polite way to say I think you are going out of your way to over simplify and to post the same over simplified comments as much as possible. I usually love reading your posts, but today, I'm a little tired of reading them. I wasn't great friends with...

I do have a few rubber hoses that are older than 5 years, still working fine. That manufacturer no longer makes hoses, and any new rubber or braided hoses, I am replacing within 5 years. I had an o2 supply line fail on my rebreather, discovered while setting up for a dive, thankfully not...
