Actually Aqualung had done this indirectly the past. They had supreme (for cold water) and non-supreme versions of the regs. The main difference for the supreme was: A snowflake printed on the housing, a added lipshield on the second stage and an ip of 8.5Bar (9.5Bar on the non-supreme version)...

Because i've read multiple times about pockets to store things away: Be aware that pockets on some bcds are akward to reach or are almost "full" after you inserted the integrated weight pouches. Just a thing to check if you buying a bcd with pockets.

What my gf magically helped was a smaller diving mask (in the vertical axis). Inbefore she tried custom mouthpieces, comfobite.. different hose lengths etc. And she was at a point she couldn't eat proper, after a dive, because it was hurting to much. The moment she started using a smaller mask...

The ear plug should have a small hole or a tube inside it so you can still equalize with it. About the pro plugs: They only help little with equalizing and are mostly meant for keeping water rushing into the ear to a minimum. Water in ears is no problem for equalization. Edit: Wild guess: Do...

Can the dive(s) be displayed correctly on the dive computer? Does anything look strange on that dive(s) Which number has the last dive?

A little bit Off-Topic: We actually have a word for that, it's "Essoufflement", i wonder if there is an english translation for that? Google Translate

About safety stop: I know left hand flat and pointing 3 fingers from below to signal safety stop. Other divers can respond with one, two or three fingers on top of their hands, for signaling the remaining safety stop time in minutes, or "sweeping" if its already done.

Yes. They give this values as specification for the cracking effort, but if you look up how they adjust the cracking effort its just: "rise the cracking effort till it stops free flowing when you 'disengage' venturi". So my conclusion was the lower mp results in higher measured cracking effort...

The older legend models. Where supreme and non-supreme versions were still a thing. Supreme being the versions with a mp of 8.5 and non-supreme of 9.5. Afaik the were/are balanced. The newer versions simply all come with a mp of 8.5 afaik.

I'm not quite sure. The service manual shows the same manual tuning steps for the cracking effort of the second stage (right on the edge of free flow) but a higher range in the actual measured values. I concluded from that, that the opening effort is higher with lower mp, but i may came to a...

Aqualung lowers the mp from 9.5 to 8.5 bar for cold water. It comes at cost of higher wob though.

Yes i tried this a few times as part of check-dives. No problem at all. The weight of the second stage pulls it down to the place you expect it to be. I'm probably switching back from the miflex inflator-hoses due to recent valve quality issues though...

When deploying the foldable one i just shove it between mask band and head. As it is pretty flexible and "flat" it isn't uncofortable and holds in place by itself. But there are also quick disconnect/connect snorkel clips available if prefered. What do you mean with "flop arround if it's not...

Required? No. Dangerous? Also no. Most people that say that it is dangerous come from the long hose around neck point of view. With that configuration a snorkel worn on the mask can hinder the deployment of the hose. Personally: I carry a foldable one with me. It irritates me on the mask...

Most 2nd stages hum/stutter/honk when dry/out of water. All my 4 aq titan lx 2nd stages do that.

Not really a tip but googling for it following shop sells mares dive computers and maybe has battery kits for that dive computers there: dive-hunt.gr | Αρχική Σελίδα Before buying a completly new computer i would maybe go to a electronics-store and look for a CR2430 battery to switch it...

How about simply getting a book about the topic and read that? Our course content was in this order: What are the dangers and advantages of nitrox and what is mod, aed, best mix etc. Calculate mod, aed and best mix by hand and use air tables for decompression. Using nitrox tables for that. How...

There is no different procedure for that. Between root canal treatments there are meds in your tooth, it isn't completly filled, also a temporal filling on the tooth crown will be made to close the canal between fillings. That temporal "cap" is okay to chew on etc. but the root canal is still...

In this context with "temporary cap" isn't meaned a filling that is later replaced by a crown but a cap from cavit or similiar material, that is used as sealing inbetween root canal treatment sessions, when the tooth isn't filled yet.

Could be a very hurtful experience. Due to the combination of a hollow tooth sealed with a temporary cap you gonna experience negative pressure inside the tooth while going down. The negativ pressure could be hurtful or even suck air inside the tooth. If air got sucked in while going down it...
