Star Wars is cool but I'm a Star Trek person. We celebrate First Contact Day.

Dude, your video clip is famous world-wide... These are just a few I found. You're a famous UW videographer!

Unbelievable! Dude! I would so love to be the one to post the first comment exposing this fraud with a link to your original video. But that honor should be yours! I would spam their comments to high heaven.

First off, yes, there is a 'Scuba Poetry' sub forum on Scubaboard. It's been deserted for a couple of years. Some of you who know me know that I have a side hustle as a publisher and writer. I'm tangentially involved in the literary community of the Twin Cities. When the lockdown started, a...

I don't think they've invented anything except a story that we've heard many times. Doesn't someone have to have a functional prototype to get a patent? They didn't even have a high-tech looking prop to use in the video. How are they going to dupe tens of thousands of crowdfunders without a...

Dropped tank..... If you have a DIN valve, check the outlet by attaching a first stage to it. On several occasions, I've seen a DIN outlet knocked slightly out of round from falling on its head. If you don't notice it visually when it happens, you will notice it when you put on your first...

When I had to learn the difference between a J valve and a K valve, I was taught to remember K for 'killer.' The K valve had no 'alert' system (before SPGs) so it was the 'killer' valve.

Oh yeah... I'm sure I still have one somewhere with my BFK and CO2 inflate Mae West vest. Of course, I was a very young child when those came out. (smirk)

OK, I just spoke to Airspeed on the phone. They've told me that the issues are temporary, a cross between the shut-down and their internet people. Airspeed Press is still out there. I've been told they will return.

I tried the email link and it looks like it's shut down. Does anyone have any current contact info for any of the Air Speed Press people? I want to talk to them about resurrecting their catalog.

I've been thinking of subscribing to a VPN just for online security. Would this strategy ban anyone who logs on through these VPNs?

One other remote possibility to check on... Some paintball gun systems are pressurized with nitrogen. There are differences in the valve outlets but some paintball suppliers might pump nitrogen. It would be more likely to get nitrogen from a paintball fill than a scuba fill. Thank you for...

How was it determined that the bottle had 100% nitrogen? Who did the analysis? Generally, nitrogen level is checked by measuring the oxygen and assuming the rest is nitrogen. Do we know it was nitrogen in the bottle and not argon? Even if the tank sat for a couple of years, it should be...

Never seen one of these before.....

I think part of the reason this has gotten so much attention is that this is the type of misstatement that climate change deniers will seize on as evidence of a liberal conspiracy. There are political ideologies that say global warming is a lie used to promote socialism. They use things like...

When I first saw the thread topic, I thought it was referring to an an novelty wetsuit said to repel sharks. It had the words, "Not Food!" printed on it. I do wonder about the science behind the suit. How much study has been given to its statistical effectiveness?

Who dives with an 11.5" colorectal tube? I thought 14" was standard.

I can do better than CF for cost and questionable benefit. I got my hands on a titanium back plate. It's heavier than aluminum but lighter than steel and would retail for about $500. It is the ultimate in expensive uselessness. But on the boat someone asks me what plate I dive, I get to look at...

Yes! The Nik III was the '69 Mustang of underwater cameras. In the '80s, I could have it rebuilt for $150. It was cheaper to let it flood every 3-4 years and rebuild it that it was to spend $85 a year to have its annual service. It's manual controls taught me all about Fstops , ISO and shutter...

I'm generally dubious of technology breakthroughs on crowdfunding sites. The technology sector has venture capitalist with piles of money to invest. They would be the first to buy into this. Why didn't they? Also, with all the potential value that such a break-through has, why market it to the...
