If you dive local and have your own gear it’s pretty cheap, ya. Once you travel the cost per minute underwater goes way up of course. People dive into the water (even freezing!) buck naked and have fun doing it; you don’t “need” anything at all. If you’ve got your mechanical timer and depth...

So you’re doing “multi level diving” by diving one level at a time over multiple dives, with surface intervals between? I suppose that works, you see everything there is to see, do all the diving there is to do, and you don’t “need a computer” to do it. You’re working awfully hard and spending a...

When I took my PADI open water 30 years ago I learned and used tables, so I know the basics. They assume a ‘square profile’; if your maximum depth is 120’ and your overall duration is 50 min, you’re pretty bent! That’s a very routine computer dive but the black box is giving me real-time credit...

If you stay shallow, use a small tank, and have a long surface interval, you don’t need much at all. As they said back when: “you can’t get bent on a 72”. No need for depth gauge if you know you’re staying shallow. No need for timer if your tank is too small to stay down long. No need for tables...

Sounds like your screwed. My sister had to give up diving because of ear issues. She went to school to be an instructor and did really well, but when she started working steady she just couldn’t equalize. Surgical widening of her tubes wasn’t an option either. Sometimes our bodies just can’t...

I think the people who like them want to snorkel without knowing how to snorkel. It’s not all that hard to learn but with the full face version there’s *nothing* to learn. You just strap it on and get in the water. The wisdom of this can be argued but that’s the pitch. Want to go deeper? Have I...

That modularity might allow different sizes and stiffnesses of blade without producing and distributing every possible permutation. Doubt they can make the mechanical joint light and durable enough to make it worth it though. I wish Scubapro the best but I think I’ll wait for others to take the...

That issue seems easy enough to code around (not being a coder). If sellers report their general location that should be searchable by distance, if they don’t you’re assuming it’s shipped from the 48 and most likely Fl.

My brand new phone somehow joined me diving on Ogden Point, BC this September. Always a complex chore packing the rig out to the lighthouse, it somehow ended up in my drysuit undergarment pocket. Suit didn’t leak (much), it seems unaffected by the pressure as well. Was sure happy to see it...

What would be behind that? Is it a covid thing, or are there deeper political currents at work? Do the mexican locals not like temporary tourists who never seem to leave?

The people who (poorly) recycle tires could likely take fins too. They’re similar in construction.

You can get a cylinder stamped for ten years in Finland?

Says it delivers more air than a normal (Al80?) tank, while weighing less, despite having a bunch of batteries and pumps and stuff. Does it run 5000# in a carbon tank to do that? Says it manages buoyancy by pumping corrosive seawater at very high pressure into the tank, with a bladder to...

I like magnetic switches, won’t buy a mechanical switch dive light because I’ve had a few seal failures with them. Infinite dimming sounds like it might be nice, better than clicking through a dozen settings. You never answered your own question though: why CAN’T he turn it on quickly? Is...

Seconding the previous: PADI is wrong. Keep minimal air in the suit, just enough to avoid squeeze, compensate your buoyancy with your Buoyancy Compensator. Getting air out of the suit is tricky: even fully open the valve needs some resistance to keep water out and you need the right posture to...

Pony bottle is for solo. You can say “solo diving isn’t recreational diving” but trust me: it’s a thing that happens. I recently had an insta-buddy who buckled his on because he’d never met me before and wasn’t sure if he was effectively diving solo or not. He decided he wasn’t and took it off...

Why not just screw those valves back in? If you’re going to tumble, clean, and inspect them later it hardly matters anyway.

An AI computer is all you need. If your computer breaks just come up slow. Being able to do that anytime is the whole point of rec diving.m! Analog backup instruments in your luggage might save your trip so that’s nice to have, no need to take that redundancy in the water at your level.

That sounds horrific for everyone involved.

I’m mostly worried about my contact lenses floating out with my eyes immersed, so I close my them and work blind. I don’t really need vision to do the sorts of things that need doing with the mask off so it’s not a problem. I certainly don’t experience any weird phobias or anything!
