The RCN seemed to think so and as a war grave it's technically theirs right?

Weezle extreme+ with a heated vest. 1) its warmer and 2) lasts literally decades longer than any thinsulate insulation

This is how electricity works lol Put an analog compass on your left arm or a kayak compass on the scooter body with mumetal between the batteries and the case (if there's room)

If you're solo and/or without any local knowledge you might just pick one of the (rare) baby diver sites cause there's more to the OR coast than just surf - the rips and currents can be obscene. Oregon Dive Sites

My little 125cfs are $38 now I think. I pay way more for 2 of those than a single 250 BUT I got them in my pre booster days and was running a cascade to fill my deco 40s to 2000psi at the time. I own them and it's hard to justify buying a 250 which is a beast to get in and out of the truck &...

You offset excessively heavy fins by changing them to a lighter neutral model. The fact that you use 11lbs of weight in a BP/W and 0lbs weight in a Xdeep is problematic - either something else is changing significantly or you're mis-weighted in one or the other or both.

A big-ish issue with the flexible manifold is the permeability of the hose to helium. So you have to shut down the cross-over valves during storage and there's a very real possibility of filling them with a closed valve or ending up with different mixes in the different tanks. It's a necessary...

Only 1x 250cf? Just get a couple more, they are vastly cheaper than a membrane system. How deeply are you drawing that bank down? I have 2x 4500, 2x 3600, 3x 2200 bottles for about the same volume as you. The 4500s never get below about 3200, the 3600s I draw down to perhaps 2500, and the...

200bar valves have no problems with 300 bar pressures. My carbon fiber tanks have 200 bar valves, they are filled to 4200psi right now (just under 300 bar). The 200/300 bar fitting distinction is complete nonsense similar to the mostly French effort behind the M26 fitting. None of those have...

Well they can! Although like 4 sigmas of those errors are human input errors, wrong gases input, wrong gasses selected, wrong settings. The less than human input errors are flooded & failed battery kinds of things. That people are not recognized as making at least some (math) mistakes even at...

There's nothing magic about DCIEM. I would just use the normal Buhlman and nudge up the conservatism for a week of 3-4 dives per day. Nitrox, but not diving up to the nitrox NDLs, taking a partial day off mid week, staying hydrated, and limiting alcohol will do way more to lower your overall DCS...

Nothing changes for me. I use the exact same necklaced left and long hose right whether there's a buddy or not. I do change up hoses and routing for no-mount, which isnt exactly "sidemount" anymore but they're independent tanks so its sort of related.

I agree - I'm just saying the while you can fairly reliably expect a 70ft bottle has 50% (mostly), the expectation that the 120 bottle on the shop floor has X/Y contents is even more erroneous

Who knows what will be on the market then, although there's A LOT to be said for diving a unit which is common amongst your buddy group. Diving a rare unit which nobody in BC dives poses real problems what you want to tweak your configuration or adapt to something new. Same with being on mixed...

There is no single gas that everyone agrees on that goes into a 100, 120, 150, or even a 200 bottle. Past 20 and 70, the MOD =/= and particular gas although it's usually just no more than 2 options. 120 is 35/25 for some folks and 30/30 for others for instance. 150 is 21/35 for some and 25/25...

As you know, there's much more than $2k for the membrane There was a leased membrane system in a local Seattle shop called Starfish back in the 2005-2008 era. They went bankrupt trying to make the payments on their vastly excessive LP pump, LP storage, gas heater, filtration, and membrane. Dive...

Pull off the shrink wrap and take some photos. They are 2x 3S2P packs = 10amp total. The stock cells are 2600 mAh Sanyos. The two packs are wired in parallel, with both feeding the backside of those banana plug fittings. There will be a small plastic insulator under the disk preventing the...

It's been "coming soon" since about 2019. You might end up retired from diving before it's actually available.

Facebook fanbois - most of whom have never consistently dived any other unit. And a good chunk of the sidewinder instructor corps flat out lie about their training and experience on the unit. I dove a v2.7 Meg for nearly 3 years and 125-140 dives before getting the sidewinder. The built quality...

SM CCR is great at actually cave diving. Everything else its terrible. Tilt head up? Flood the cells with goobers, float on the surface? can't breath, zero water trap, no place to put a 2nd deco gas, its a bitch to have a stable suit gas spot, suit heater pushes your SM tank out into...
