In the last 3 years, I've been through (personally owned) the following. All diving in ~40-50F water (Vancouver Island) year-round. Ranking how long I would comfortably dive in each of those combos in winter (~40F water): Fusion one-piece 45 mins 4th Element Arctic 2-piece 30 mins 4th Element...

I, also, have dove a single tank exactly twice since switching to doubles in 2020, even though ~75% of my diving is still recreational local shore diving. Rather than switching back and forth between singles and doubles (and the associated hassle/extra gear of extra reg sets, wings, single tank...

FWIW, I had that exact multitool in my wetnotes, but when I had to try and use it to remove a LP port cover on a boat a couple months ago, the hex head (which is square) stripped out instantly.

I don’t think a lot of wearables have GPS-based compasses any more, do they? The very low cost of integrated IMUs with magnetometers has made that mostly obsolete (I think)

If you open the Onshape file, you can right-click ‘Part 1’ in the lower left pane, go to ‘Export’, and chose as STL or STEP. If you want to change the light diameter, create a copy of the file and edit the light diameter variable. If you’re having problems, PM me the light diameter you need and...

FWIW, I also have a good hard Goodman handle model for the D26, with a similar thumb loop setup and a guard for the button. It’s what I use for my primary setup (most of the time).

I can also recommend the Divesoft flow limiter that goes into an LP port, which gives me identical results to the Professional flow limiter, while being much cheaper. I tried it with the Forensics Detector CO monitor linked further up the thread earlier today, and it seems to work well (although...

The o-ring on the light head has nothing to do with retaining it, it’s just a marker I keep on my backup lights to differentiate one from the other (my primary and backups all use 21700 batteries, so I rotate cells through backup 2 > backup 1 > primary > recharge to keep things fresh). You’re...

In my endless quest to make more light handles, I've been playing around with a very simple Goodman handle design, with a rigid light mount and and adjustable bungee hand loop. If anyone is interested, the fully parameterized Onshape model is here: Bungee Goodman Handle Some benefits of this...

According to the manual, it’s based on: So it does have a compass, just not displaying the headings to the diver, which sucks. My guess is that it uses IMU/magnetometer data, and then uses the exit GPS location to error-correct the course. If they got fancy, it might also use the pressure...

No, internally they're identical. 230bar is the limit on yoke connectors, DIN connection can be as high as 300 bar (although many DIN valves are only rated to 230 bar)

New Suunto computer. Notable features (to me): Inertial navigation! Well, sort of. According to the manual, you can view a track of your dive in the app afterwards, but not during the dive. I'm assuming this is a) due to processing limitations, and b) because it uses the GPS start and end...

I had Kubis previously; I now have the Santi system on one suit, and the PSI system (an aluminum knockoff of the Rolocks) on my other suit. I like the Santi system the most, mostly because the flexible/soft rubber ring is the least bulky and doesn’t mess with lights or scooters. The Kubo...

Canadian dollaridoos, so $2.33/cu ft in Freedom units. No booster fee either :cool:

Unless I'm missing something...I thought this was accepted best practice (and GUE SOPs) for deco bottles - dive with the reg pressurized but the valve closed.

FWIW, I have got through to someone when calling the number listed on Google Maps before (after they left items off an order, and ignored emails about it...). The person on the phone wasn't exactly any friendlier, but it did resolve the issue!

Curious if you know of any testing/source for this? I always assumed that purging a reg into an unconcious victim's mouth wouldn't do much good, as the air would just come out of the exhaust valve. Rescue breaths and bag valve create some amount of positive pressure that (I think) would be...

Seems like the article isn't available online anywhere, but I'd like to read the paragraphs following this. That text doesn't actually say that you provide in-water chest compressions - it says that you have a "decision to make", and that the victim will need rescue breaths and chest...

I haven't actually changed my shaft seal yet (if it ain't broke, etc), but the procedure looked very straightforward when I looked it up. To save $$$, I definitely recommend buying the VESC from Flipsky directly and flashing it yourself. Be warned, some of the other low-voltage components (i.e...

Programming the VESC is very easy. I did it myself - after buying a replacement board from Dive Xtras that arrived completely DOA, and their refusal to help, I realized that they use an off-the-shelf Flipsky VESC 4.2, and the firmware to flash on it is available on Github. As long as you have a...
