Stay calm and look at your depth gauge constantly. Fin normally perpendicular to the current if the bottom is nowhere near you. Add air to your BCD while continuing to carefully monitor your depth. When you begin to ascend consistently start dumping air from your BCD to maintain a safe ascent...

I have to assume they weren't planning to dive to anywhere near that depth, given they were reportedly AOW divers. Seems like it was a recreational dive gone very wrong.

Yeah, agree with the above. I'm also on the west coast and have done several Indo/Pacific trips to remote destinations away from an international airport, but always for a minimum of like 10 nights. When the travel time on each end can easily be 24-36+ hours, going for a week seems pointless...

Yeah, with modern equipment and assuming divers are are weighted within reason (eg. not 10lb negative at the surface), there's hardly ever a reason to ditch weights. If you're at depth with your BC/wing nearly full of air just to stay neutral and no headroom to get positive and ascend, you're...

The argument is silly because no matter what she did or didn't do it's not the shark's fault. You go in the ocean, you accept certain risks because you don't belong there. Sure she may have taken certain actions which made a violent encounter more likely (though the accounts are...

Yeah understood, I was just pointing out that it's a waste to use Novus, a plastic polishing compound, on glass. Literally any other cleaner will work as well or better for much less money.

The novus stuff is great on plexi, but won't really do anything on glass aside from acting as a cleaner. Glass is way too hard, and if you do somehow manage to get actual scratches in glass, novus isn't abrasive enough to grind away material from glass.

Nice toy, I might need to check that out. I have one of the rocket squeeze blower things every photographer has in their bag, but that looks to have a lot more utility minus the arm workout.

CLR cleaner (calcium, lime, rust) works well at getting salt spots dissolved. Safe on glass and any hard plastics like plexi. Then you can clean it up with water and a soft cloth after that.

I overheard a SCUBA diver on a recent trip while doing their paperwork just after arriving at a resort say "no I always use oxygen" in response to a question about nitrox. No, they did not have a CCR.

The air can probably manage most of that. It might be worth considering the pro though for other factors, like potentially a bigger/better display (depending on size choice) if you're not gonna be plugged into an external monitor.

Yes, but it's extremely application dependent and many of those big improvements are only in some relatively narrow use cases. So you need to research the benchmarks to see what apps actually benefit from that performance and decide accordingly based on your usage. For instance, modern macs...

If you love Macs and are already committed to that ecosystem, get a Mac. If you're open to getting the best price/performance (plus much better repairability), get any one of a number of Windows laptops instead. The "Macs are better for creatives" thing is a myth and always has been. It's...

Ok, apologies for the now-deleted post making a joke, but seriously, this is not a shark attack. She knew the shark was there and deliberately engaged with it anyways. Hopefully someone somewhere learns something from this.

That sounds rough, sorry about that. Not the way you want to do your fist liveaboard. Your experience was not typical, especially for what is supposed to be a higher end boat (AFAIK). If you're happiest at a more relaxing pace diving 2-3 times a day you're correct that liveaboards in general...

Yeah, not saying a guest can't have a good experience with one of these operators on a given trip, but that sort of operation is just setup to fail spectacularly more often than not, and almost certainly when you most need them (like in a life and death situation). Definitely glad it worked out...

That's what you get when they have to cut costs to the point where they can cover expenses for $1000-1500 per guest per week. They outsource all the non-diving crew, along with all the safety and maintenance, to the lowest bidder. You get what you pay for guys. At least up to a point of...

Yeesh. Egypt has been on my list for a long time, but it's gonna take them years of good faith effort with the industry there to get it to the point where it's even worth considering, in my opinion. What a shitshow. If this was an isolated freak accident that'd be one thing, but they're...

I'll look into airtech for the future. Looks like they've got a good system and folks here seem to be fans.

Dimensionally the front of the DS160/161/230 are all the same width because the same Ikelite dome diffusers fit on all of them. The only real difference is the 230 has a slightly dome shaped front piece of glass, which I suppose could matter in some cases.
