It was their travel insurance, yes. We were bot on a liveaboard (though I don't know why that would matter). On each trip either my wife or I were hospitalized (neither hospitalization was for DCI, though it was suspected at first). Importantly, we did have to pay up front because the foreign...

We've used Allianz several times for months-long trips to Bonaire (in addition to DAN insurance). Twice we've had claims, and twice Allianz has come through without question. We did have to follow the policies directly. We like Allianz so much that we've opened for their year-round travel...

I've been playing with this, and I think you're right about it being basically a bubble of air that gets trapped in my outer ear for a moment, displacing the water.

If I could spend my entire day watching Taskmaster, 8 Out of 10 Cats Does Countdown, and QI, it'd be the best. I'm annoyed with Channel 4 that I have to use a VPN to change my IP address to London so I can stream shows.

I really wish I was Richard Ayoade. I've worked hard to tone down my enthusiasm because he is my idol. (Seriously, if I could take a Russian vacation with Greg Davies and watch him being throttled by tree branches, that would be the best day ever.)

He doesn't list either for this specific equation. He's working ppHe and ppN2 in a trimix breathing mix.

@John C. Ratliff I agree that a lack of units is maddening, however there may still be an error in your calculations. I get the same numbers as Salama when working longhand, except for the misplaced decimal. @dmaziuk That is also the number I have found when searching PubMed. Since he doesnt...

I'm currently reading the aforementioned book. I've made it through Page 45. The book is dense and tightly packed with information. Now, for full transparency: I am not a technical diver, nor am I planning to become one anytime soon. (I think it would be fun and challenging to learn and use new...

I recognize they all call for "help" differently. In most of the threads about these types of beacons, it seems the general consensus is some level of, "it wouldn't be bad to have both a PLB and a PAB--for various reasons." Wouldn't an "all-in-one" system like this seem to be the best approach...

Funny. I just ordered a canister from DryFob last night under the assumption I'd be buying one of the other ACR PLBs. Then I saw this thing. I didn't realize the device was so large.

It looks like ACR sells a model that is basically identical to this. I'm just curious about the AIS, 406, and 121.5 all in one features and if anyone has tried them.

I know it seems that this thread is now focusing on containment for PLBs, but have any of you had experience with the PLB3 from OceanSignal? (Maybe this has been covered before. I read through the first 63 pages of this thread, but haven't been through the additional 65 pages.) I'm just curious...

We are both getting cold diving dry in cold water. We dive identical rigs. She believes we can help minimize the cold by simply adding more weight so we can, in turn, add more aire to our drysuits. I think this will cause a buoyancy control issue. My solution is to add thicker undergarments...

This was my question slash concern. I'm not a doctor, but I enjoy browsing PubMed in my freetime. I only recently learned about IPE and have gone down a rabbit hole reading anything I can get my hands on on the topic. Yes, blood pressure issues I understand. I had never read literature about...

Yeah, I've been watching this case for a couple of weeks. I tried to reach out to the Assistant Coronor who filed the report this article is based on. While I did find the report, I can't find contact information for the coronor. Nowhere in the report did she elaborate on how the mask or the...

I'd ditto @stiebs. Darktable's learning curve isn't any easier than Lightroom (in fact, Lightroom might be easier since [most] of it is just sliders (unless you really want to get into understanding how each of the sliders do what they do). You won't need to install and uninstall Lightroom or...

I don't mind GIMP as a free photo editing suite, but it has some limitations and a steep learning curve for what most beginners are looking for. I also enjoyed Darktable for that same reason. I used to teach them both in my Imtro to Photo Editing class at our local Community Ed. However, Adobe...

I'm confused by the wording here. Are you saying that, instead of putting a red filter over the GoPro lens, you used an external light with a red LED? Either way, you state here that you expected the images to have a blue cast to them, so . . . what is the problem? If you had expected the...

This might be deviating from the original thread, but I think it's important to point out a particular bias among those of us here on ScubaBoard. First a clarification: Despite having my OW course taught on my knees or standing on a platform, I am a firm believer that OW courses should be taught...

Nothing new to add. I just wanted to wave at a fellow Minnesota diver. Hiya!
