We're all very sorry for your loss, it sounds like he was a remarkable person. Thank you for sharing, it's good to be reminded of the humanity behind the statistics.

"The Cloud" is just a buzzword that means "other people's computers". They might have more servers and a budget for engineers, but they don't actually care about your data. Nobody should rely on the cloud for backups or mission-critical data. It's like the AWS outage last year, they've...

Me browsing this thread, running out of excuses to upgrade my camera. The TG-5 is legitimately a great camera though, I use it above and below water pretty regularly. MFW I blind my buddy with my strobe when he's least expecting it. Got to take it to Socorro just before Covid hit, and it...

That's also what I'm seeing in my own comparisons. I just graphed 10-40M for PADI, DCIEM, and Buhlmann and the differences are vanishingly small with depth. The PADI table NDLs actually seem to be the most aggressive of them all until around 40M, probably because those come with a "mandatory...

With Shearwater supporting DCIEM upgrades for commercial and military applications, I thought this might have been discussed here but haven't found much with searches. I live and dive around Victoria BC, and have done some contract work on the boats that the Canadian Navy Fleet Dive Unit use...

You pretty much nailed that summary. Research has indicated that fast tissue compartments can tolerate more overpressurization than slow compartments without developing DCI, which means getting shallow sooner is better. If you're within NDLs, there's no scientifically sound reason to add a stop...

Canadian military salvage/clearance divers use Fusion suits, formerly made by White's, now Aqualung. The closest civilian model would be a Fusion Bullet.

I picked up a couple DSMBs from Piranha, even with the exchange rate and shipping it was half the price of any LDS offerings.

I'm getting an error message from Firefox when I try to visit the site. www.deep6gear.com uses an invalid security certificate. The certificate expired on November 29, 2019, 1:13 p.m.. The current time is November 29, 2019, 1:25 p.m.. I can't even force it to use HTTP because HSTS is turned...

There it is. I figured I was forgetting something. Active duty Navy/Coast Guard and warehouse workers are assumed to be in full working order, I suppose.

Has anyone ever seen/tried a Christmas tree ladder with alternating steps? I've seen alternating tread stairs on some ships and warehouse ladders, and they work shockingly well. It would also make for a lighter ladder since you'd only have half the number of steps.

With a bit of practice I bet a reasonable facsimile of a Freedom Plate could be made that way.

My understanding is that the wildlife varies depending on the time of year. Nautilus has a chart: https://drhmkr8s3o2fc.cloudfront.net/wp-content/uploads/2019/08/SocorroConditions_2019-1024x630.jpg I'm going next March in part because of my interest in seeing whales.

I highly recommend it, I received a copy as a gift from a family member and it's a wonderful read.

My AN/DP course (one dive left) has all been air backgas. If you dive the best nitrox mix for a given depth, you won't have a lot of deco to do. Which is normally a good thing, but not so much when you want to get practice with actual deco. Plus air is cheap/free depending on the deal with your...

One thing to be aware of is that firefighters can get away with more contamination than divers can because they're always at 1ATA. If there's a negligible-at-the-surface amount of CO in the system, the partial pressure of CO at depth could mess up your day. So make sure they test the air regularly!

The dive planner is a killer feature, especially for planning multi-gas deco dives. Being able to drag and drop the waypoints and immediately see the effect on the deco plan is invaluable for developing an understanding of decompression. I've played with other programs like MultiDeco, but the...

Subsurface is a free, open source logging and planning tool that works on Windows, Mac, and Linux. It has built in cloud functionality that allows you to synchronize with the Android app, and supports most modern dive computers. You can save the coordinates of sites you dive (and even mark the...

If the history and science interest you, I can't recommend Deco for Divers enough. It's by Mark Powell, and if you're interested in technical diving he has a book about that too.

A warm water soak did the trick for me when I had the same issue.
