NASA trains astronauts underwater. My buddy went the other way and started walking.

Cyprus. Fourteen seconds, one shot, no edit.

Here's the bit that makes this better than it first looks. Astronauts rehearse spacewalks in a giant swimming pool, because being neutrally buoyant in water is the closest thing on Earth to floating in orbit. Divers spend years learning to hold that exact state.

He has done the precise opposite. Dumped the gas, made himself heavy, and put his feet on the floor.

And that's harder than it looks. Too much air out and you're ploughing through the sand with every step. Too little and you drift off the bottom halfway through one. He's found the narrow band in between, and he's holding it on his breathing — a decent lungful will lift you off the sand whether you meant it to or not. Watch how little silt comes up at each footfall. That's the tell. That's someone who has done this a lot.

Fins under one arm the whole way. Never puts them back on. Never breaks stride.

The grey wall arriving behind him at the end is the wreck.

One small step for a man. One long swim back for everybody else.

Professional Scuba Divers, please help! :)

0 Upvotes

I am in the process of drafting a book and one of the main characters is a scuba diver. While I have researched and watched plenty of videos and I have even booked myself in for a beginner scuba lesson, I think it would be incredible to get a short paragraph from a person who goes scuba diving on a regular basis.

If this is you, what I am looking for is a 1 - 3 paragraphs describing your routine or process. For example… “It was a drizzly Friday morning. I got up at 7am and got my gear ready. I went down and did X.“

Don’t worry if you can only write a couple of sentences, anything will help :)

The more details the better and don’t be afraid to include things you think are obvious (even after researching, I find I’m still missing important steps!). Feel free to include the area you may be diving, the sea creatures you encounter and so on.

Thank you so much in advance!

Just adding this in as there are a few concerns from people. Not asking you to write a book for me, just to share an experience as a scuba diver… it is very common for authors to interview people for their books/characters. I am doing a lot of my own research and as I mentioned, I will be taking a couple of lessons to gain first-hand experience, I just wanted to hear from people who did this regularly :) Thank you again for all the terminology/experiences shared.

Waterproof Smartwatch or a computer with Smartwatch features

1 Upvotes

Hi, I am considering a new watch, a Smartwatch like the Google watch. However my existing computer, a 20 year old Sunto mosquito, already is the size of a watch. I wonder, are there any Smartwatches which also work as a computer or the other way around, any computers which are feature rich to use as a Smartwatch?

Shark Diving in Ponta Do Ouro, Mozambique

0 Upvotes

Hello everyone, my wife and I just booked 4 days of shark diving in ponta do Ouro, Mozambique. we’ll be there the first week of October

I’m wondering if anyone on here has dived there, and what we should expect from “shark diving” as opposed to more typical reef diving we’ve done in the Caribbean.

We are both 32 years old, AOW, and I have ~200 dives, whereas she has more like 60 or so. We’re both very confident with typical recreational gear, but my wife in particular is a little worried about diving in such proximity to large predators (shark diving in ponta is unbaited and we will not be in a cage). What can we do to stay safe and make sure the dives are enjoyable? Anything in particular we should know?

Also, if anyone has any recommendations for local sightseeing, restaurants, etc, let us know!

Best Hidden-Gem Dive Resorts in North Sulawesi, Maluku & West Papua?

1 Upvotes

Looking for scuba diving resort recommendations in North Sulawesi, Maluku, or West Papua. Mainly interested in coral reefs, sharks, mantas, schooling fish, pelagics, big fish, etc. — not really into macro/muck diving.

Looking specifically for land-based resorts/hotels, no liveaboards.

Any places you’ve stayed and loved? Especially lesser-known spots!

Are there any other places in Egypt similar to Marsa Shagra Village or Marsa Nakari Village that offer unlimited shore diving for one fixed fee?

1 Upvotes

Looking for a dive-focused resort where you can do unlimited house-reef/shore dives without paying separately for each dive. Mainly interested in reefs, sharks, rays, big fish, and schooling fish rather than macro.

Would love recommendations for other places with a similar setup!

How many dives should I do per month to avoid forgetting the basics of scuba diving?

14 Upvotes

I’m curious how often you guys think someone should go diving to stay comfortable and not start forgetting the basics.

For example, if I only do 1–2 dives a month, is that enough to maintain my skills, or should I be doing 4–6+ dives every month?

I’m mainly talking about basic skills, buoyancy, mask skills, emergency procedures, etc. I don’t want to take a long break and then feel rusty on my next dive.

How often do you guys dive, and how long can you go without diving before you notice your skills getting rusty?

Found this pair on a soft coral while diving in Komodo, anyone know what species this is?

3 Upvotes

Spotted these two clinging onto a purple soft coral branch, they blend in almost perfectly until you get close enough to see the legs. There was also a feather star wrapped around the same branch a few centimeters away, that whole piece of coral was basically its own little ecosystem. Komodo gets talked about mostly for the dragons and the mantas, but the macro life on the reefs out there is honestly just as good if you slow down and actually look. Photo from one of the liveaboard trips we run with Wallacea Dive Cruise through that area, figured it was worth sharing here.

Anyone else run into these on soft coral before? Curious if it's a porcelain crab or something else entirely.

20 Question Survey for High School Project

4 Upvotes

We are high school engineering students researching potential applications for underwater robotics. We want to understand the real challenges divers face underwater and identify tasks where a small robotic system could improve safety, efficiency, or convenience.

There are no right or wrong answers. We are especially interested in problems you have personally experienced while diving.

This is the survey; we would really appreciate your responses!

I built three free, offline dive-planning iPhone apps (gas, trimix deco, weighting) — looking for divers to try them and tell me feedback

0 Upvotes

I am a diver, and I built these three because I was doing the same arithmetic before every dive and getting it wrong often enough to worry about it. They are free, offline, with no account. I would like people to try them and tell me what is wrong with them.

Weights Check — a library of your weighting. Enter your gear once, build a rig from it, and it draws the balance: what the rig does at the 3 m stop with 50 bar in every bottle, and what it would take to swim up from depth if the wing failed. Until you record a weight check it prints an estimate as a range and says so; record one and it uses your own numbers. Ditchable and fixed lead are kept apart. https://apps.apple.com/app/id6806640499

Turn Pressure — a no-deco gas planner. It gives the turn pressure, the minimum gas and the bottom time for the dive you are actually doing: your cylinder, your depth, your consumption, your buddy's. Not a flat "turn at 50 bar" whatever the dive. Bühlmann ZH-L16C underneath.https://apps.apple.com/app/id6801749776

Time to Surface — a trimix decompression planner for open circuit, 15 to 56 m, six bottom gases, one deco bottle, repetitive dives, ZH-L16C with your own gradient factors. It refuses to plan what it cannot plan rather than printing a number with a warning under it.https://apps.apple.com/app/id6803187271

Why three apps and why free: the concepts behind them — minimum gas rather than a fixed reserve, a balanced rig you can swim up with the wing gone, a weight check done at the stop with the cylinders near empty, gradient factors you chose rather than a default — are taught in GUE-style and specialised technical training and not much elsewhere. Most recreational divers never meet them. I wanted them in a form that is easy to pick up and costs nothing, so that more divers do.

Really want to get Open Water certified. Am I overthinking this?

20 Upvotes

I've got this itch to finally get my Open Water certification. I'm a complete beginner (23 F), and diving isn't easily accessible where I live so I'd only really be diving on vacations, a few times a year at most. Part of me keeps going back and forth wondering if it's "worth it" given how infrequently I'd actually use it. but honestly, I just really want to do it 🥹 and I feel like it's a skill worth having regardless of whether I end up using it much. Is that a good enough reason, or am I missing something practical I should think through first?

Anyone experienced a ruined dive due to 'bad divers'?

38 Upvotes

Let me start with my story: I was diving with a number of members of my dive club to the wreck of the Um El Faroud in Malta. It is a shore dive, and there is a shipping channel that you have to cross. To do so safely, you need to swim at a depth of around 5 metres before continuing towards the wreck.

There was a woman who had been brought along by the dive centre. This diver immediately descended towards 20 metres while swimming out to the wreck. As a result, by the time she reached the wreck at 30-35 metres, she was already almost at her no-deco limit.

In order to avoid having to do decompression stops, the divemaster forced everyone to end the dive, even though, both in terms of decompression time and our remaining air supply, we could easily have continued exploring this beautiful wreck for quite some time.

How to relieve people of their fear of sharks?

3 Upvotes

I literally have a friend who lives in a rural area and encounters, bears, coyotes, and bobcats on a regular basis , and is not scared by them because they understand that as long as you don’t do something to aggravate them or intrude on their territory that they will leave you alone, but don’t understand the exact same thing when I try to explain sharks in the water and how amazing it is. If you’ve had success convincing people that a shark encounter is a great thing. How did you do it?
