Glad you are doing better @DandyDon ! SB is a better place with you around, whether your actively diving or not!

6 year old post, OP last on SB 6 years ago

Yes. Did you mean "...what was the 6 year old doing scuba diving?" If so: Valid question. It was allowed by whatever "requirements" the provider had. It was offered as a shore excursion on our cruise, sounded like fun, and we didn't know any better at the time. As I said, if I knew then...

Would love to take your app for a spin, alas I am on Android. Have been on the verge of making the change to Apple. Perhaps feedback from your app will push me over the edge :D

This may be like a "class" my family of four did, at my insistence, on a Caribbean cruise. We had zero experience. Did some confined water drills, reg recovery etc. Then, after a 15 minute boat ride to another cove, they basically turned us loose in 30 or 40 feet of water. Daughters 6 and 9 and...

Yes indeed

Ain't that the truth

Seems like a lot of added complexity and failure points just to avoid reg swaps and to allow isolation.

THIS! And eloquently stated @rddvet I was waiting for some typical SB "tough love" that hasn't yet come, but I like your response even better.

Some units have an easy to add inexpensive hose hanger option 🙂 #choptimaftw

Sweet!

While exceedingly rare, the chances THIS happened are infinity more likely than symptomatic increased CO2 retention due to the infinitesimal increase in gas density from 21% O2 to... What was it? 32%?

Yeah, and at recreational depths, rebreather divers diving an SP of 1.2 will ALWAYS be breathing from loops with an fO2 above 21%. It defies logic, common sense, AND the asymptomatic 99.99999999% of dives being done every weekend.

And it would follow that, if such a small change in gas density had such a marked effect, that doing a dive with ANY physical exertion breathing a gas with a density of even 5.2 (air at 110ft) with no observed CO2 effects would seem to be an impossibility

Second that. Just sent in my regs for their first service (free) after 2 years. STELLAR customer service and turnaround time. My first set was a set of DR. No complaints. Another outstanding company with incredible customer service.

@UofMI_Divegeek Isn't your position kind of the definition of anecdotal evidence? Just because it happened to you once, does that mean it's "an issue", especially since it doesn't make much sense, based on the math and experience of others?? CO2 buildup is a known issue, but an increased...

When they make that "puckered" face, you know it was a sourgasm
