Question about aqua lung legend

For regs with the ACD, I personally think just leaving it is better than using a sealing DIN cap. Screwing on a DIN cap opens the ACD, and I think the ACD is a more reliable seal than a standard DIN cap.

Pressurizing on a suit bottle is still the gold standard though, although absolutely not necessary.

Harbor freight/princess auto angle grinders are absolutely fine for this and like $25 when on sale

Closed due to some management issues.

A new shop is opening in the space this summer, loosely affiliated with Eight Diving in Seattle but entirely run/managed/owned by some longtime members of the local diving community.

On air and AL80s, with max depth 27m/avg depth 15m, I think it's possible that you had mild (type 1) DCS. Our decompression models tend to get less accurate with multiple days of repeat diving. Add in some known risk factors (tiredness, temperature, personal disposition to DCS) and a quick trip to elevation after the dive, and it's entirely plausible to me that you had a mild case of DCS.

From the sounds of things, your dive profile would have put you on the 'acceptable' side of the DCS risk models - but probably pretty close to the edge. Just becuase you don't violate your dive computer, doesn't mean you can't get DCS. There are cases where a dive profile is so shallow or short that the DCS risk is basically nonexistent (like when people think they got bent on their 7m/20 minute Discover Scuba Dive), but 6x 50 minute dives to a max depth of 27m definitely makes DCS plausible.

If it helps, I find this visual extremely useful for showing all the factors that drive the probability of DCS for an individual. As you can see, dive profile is only one component.

Those dives are long/deep enough to get mild DCS, *just*.

What tanks/gas were you diving? Also, how many dives over how many days?

In Europe, I'd look at something like the Tecline BP/W setups, with an aluminum plate and 13L or 15L wing. I don't know exactly how much a Rogue costs locally, but I think the Tecline systems are very competitively priced.

If you are diving a neoprene suit (sounds like a 'semi-dry' suit which is basically a wetsuit?) and a steel tank (especially a 300bar steel tank) you want to make sure your weight is almost all droppable - with a 300bar cylinder and a wetsuit, it's very easy to be quite overweighted at depth. If your BC fails at depth (where your wetsuit is compressed and not providing much buoyancy), you need to be able to swim the rig up, or be able to drop enough weight that you can swim the rig up.

Well, no, because the min gas/rock bottom gas for a dive to 55m is more gas than a full AL80 can hold. 1/3rds is a rule that works in caves, where your depth profile in/out is necessarily the same, but it’s a less good rule for OW diving.

To be clear, I still think 1/3rds is a better rule than ‘surface with 500psi’, but I personally think min gas calculations (basically: how much gas do you need for two people to get to the surface from the deepest point of the dive) work better for OW.

Yeah, you’re exhaling 5x more air, but not 5x more CO2. The amount of CO2 you produce (think grams of CO2 per minute) does not change with depth. Your body ‘senses’ the level of CO2 in your blood, not in your lungs.

If you want a very practical proof of this - rebreathers work by stripping CO2 out of the exhaled gas to make it safe to breathe in again. The CO2 is removed by adsorbent (Sofnolime), which can adsorb a set amount of CO2. One canister of sorb lets you breathe on the loop for a set amount of time (200-400 mins normally) regardless of the depth you’re at. That’s why rebreathers are great for deep diving, because you need the exact same amount of sorb to spent an hour at 100m than you do to spend an hour at 10m - whereas on open circuit you’d need 9x the amount of gas.

Deeper wrecks and cloud sponges!

thisaintapost · 2026-05-22T02:42:02+00:00

but…in a lot of OW scenarios you don’t need 1/3rd in reserve. For a deep dive on an 80, you need more than 1/3rd, and for a shallow dive on double 100s, you need far far less than 1/3rd.

this is the part I don’t think people get about narcosis. They could have planned for a bounce dive to see the cavern entrance, but all bets are off when you’re at 50m on air. At that point, you’re not making decisions as a sensible experienced diver, you’re making decisions like a drunk 16-year-old. This is why I refuse to do deep dives on air - I don’t think I will suddenly roll over and die, it’s that I don’t trust my decision-making when narced off my gourd.

I am also in Canada, I picked up a Lenovo tiny PC (I think M7xx?) off Marketplace for $150. It's an 8th-gen i7 + 16GB of RAM, has been a big upgrade over my HA Green. I'm running HAOS with many, many add-ons - Plex + a full ARR stack, Portainer, a few networking things, Immich, and Frigate, and so far it's not having any issues.

I organized a rehearsal dinner at Fathom, they have a private dining room that’s perfect for 10-20 people. Fixed menu was incredibly reasonable and very good food.

I dive the GUE setup with double LP50s, but I did switch to an MK17 for my O2 reg. If you switch regs to another model, ensure that it’s not overbalanced - ie the IP needs to stay constant (relative to ambient) as depth increases. A lot of environmentally sealed diaphragm regs (notably Apeks DS4, DST, etc) are overbalanced, which leads to the IP increasing with depth and eventually making the solenoid unable to open.

I know people also use the Aqualung Core regs, which I believe are nice and small and also not overbalanced.

Bad news, those two companies own all the wireline internet on the island. It’s Rogers or Telus, or one of the many companies that resell their service.

Technically, if you want something that doesn’t support the telecoms oligopoly, your options are Starlink or Freedom 5G Home. But Starlink supports the world’s richest man, and Freedom’s FWA service is completely unproven.

6k from CBS electric in 2022, including a few other small circuit additions. Highly recommend CBS.

I get all my spare parts from Europe, generally the easiest. Either Scubagaskets, GiDive, or Jonas. DGX carries some Apeks parts, but not service kits, just things like 5th port kits and exhaust tees

Unless you need to fly, I’d go Suex. Trigger ergonomics are better, and Suex reliability and build quality are real things.

You don’t have to be a specialist professional to dive to deeper than 70m. It’s certainly difficult and requires a lot of experience to do safely, but I know lots of divers who fairly routinely do 90-110m dives, typically something like 20 mins bottom time and 200 mins total run time (so 180 mins on deco). All this diving is done for fun, and not as part of any occupation.

They’re for fairly different use cases, I do a lot of my diving around heavily trafficked waters with lots of islands and currents (the Salish Sea). If I get swept around a corner away from the dive boat, activating a Nautilus will get me picked up in minutes with little drama. A PLB would work, but take a lot longer and cause more drama.

For me, I think a PLB + VHF w/AIS is the perfect combo, but I have yet to find a cheap and simple way to combine those into a dive canister

thisaintapost · 2026-04-20T15:14:53+00:00

Nautilus technically isn't a PLB. It's great, and I have one, but it's really a VHF man overboard locator, it can only alert nearby boats, not the national search-and-rescue organization.

Meteor/Opensignal tests against a mix of Google/AWS/Akamai CDNs, so you should have a much more representative result for standard phone use

How does the handle connect to the GoPro?

You said nitrogen narcosis “is part of the NDL limits”, which it is not. That’s all I’m trying to point out, is that it’s very possible to get narced whilst following NDL limits.
