Here is some basic info from a Google AI overview...it doesn't mention muscle tissue but one should note that muscle tissue is considered an intermediate or slow-to-intermediate type of tissue (faster than fat and bone, but slower than what is listed as "fast" type tissues: In scuba diving...

It refers to a more advanced concept/theory of tissue nitrogen loading and off-gassing. It basically theorizes that the body's tissues can be categorized into tissues that quickly absorb and off-gas nitrogen, and tissues that more slowly absorb/off-gas nitrogen. Each type is a factor and...

As a Divemaster, I do. After reading through this entire discussion thread, thus far, it seems like you are not really looking for opinions from others regarding what you expressed in your original post. Instead, it seems you are seeking validation/vindication for your opinion/mindset regarding...

I would recommend picking up either another Helix 2nd stage or a Core. The Helix is just a rebadged Core. The yellow octo of either is just a detuned version of the regular version, so there is no reason to specifically get the octo version. While the ABS octo has some merits, it is not as high...

Where did you get those shnazzy orange silicone seals? -Z

From what I can tell from the photos you posted, the only thing that looks like it a could be a US Divers/Aqualung 1st stage part is the knob on top of the yoke. The squared body where the yoke attaches does not look like any of the versions of the Calypso that I am familiar with. I also am...

I am not understanding the "cross-contamination" argument some have made here, especially in the context of affecting a fill station. I can understand that if the ambient chamber is filled with a non-O2 compatible lube/substance, the piston o-ring will effectively slide against the ambient...

Rolock 90 is a great solution if one has the Si-Tech QCS oval wrist ring system installed...in the OP's case, the original Rolock (1/2/3) is the more optimal solution. For all reading: The difference between Rolock 1, Rolock 2, and Rolock 3 is the diameter of the retention rings that keeps the...

There are other whistle designs that are as effective in a slimmer package: These can be easily and relatively unobtrusively attached to the corrugated hose with a short length of bungee and then further kept in place, tangle-free with a section of inner tube slid over it, as others have...

Fixed that for ya! -Z

Congrats on the win!...and thanks for posting the follow-up. -Z

You should check with shops in your area to see if they service Mares regulators. If you can't find anyone local, I would get in touch with Chris at divezonescuba. His shop is located in Pearland Texas (just south of Houston). Last I knew, they were a Mares dealer and should be able to help...

Yes...it is in the form of a course taught by rsingler. Contact him directly by clicking on his name and selecting "send direct message" to find out when he will offer the course next. Cheers, -Z

I know after our initial push for this initiative that I kind of let it go...but a few months ago, I finaly sprung for a PDF editor and have been thinking about the original initiative I proposed regarding breaking the manuals apart by each 1st stage and 2nd stage as stand alone PDFs. I have...

Essentially the MR16 and the MR22 are the same first stage with a different exterior form factor. The same is true of the Voltrex and the Abyss 2nd stage...relatively, everything is the same with the exception of the faceplate. I state "relatively" because there were some minor changes to the...

No special tools are needed to service your version of the MR22, other than the IP gauge you already have. An inline adjuster to set cracking pressure on whatever 2nd stage you decide to use will make this adjustment more convenient, but it is not necessary. If you pickup an Abyss 2nd stage...

The ones we have... Back cover states: Product No. 79102 (Rev. 05/17) Version 3.08 Copywrite PADI 2016 Front cover: -Z -Z

What is the most recent edition and when did it come out? I have 3 copies of the book, but I don't know if it is the current edition or not. -Z

Cove Island park in Stamford is within your specified distance, without much current, its a beach entry with a bit of a long approach from the parking lot so its best to have a cart to tote your gear. Another place in Stamford is out near Shippan point...there is a small private beach at the...

Skip the seal tape and instead install the Si-Tech QCS oval wrist ring system....while you're at it, install their Quick Neck neck ring system too and you will not need to Faff with gluing seals again. -Z
