You can absolutely hold your breath as long as you are at the same depth, and not going up or down , I got certified to scuba dive when I was 13 I am 52 now. When I’m diving , once I am at a level depth I take a breath & I hold it for about five seconds then let it out slowly , because of this technique I use,,,, My air last 20 minutes longer than everybody else’s. Most people get about 35 to 45 minutes at 50 feet , Me, I get up to an hour with plenty of time for my ascent to the surface 😮 The important thing is to not hold your breath while swimming up , the air will expand I am bad things will happen to you

That bag of chips is pure air

Well done guys! Can't wait for your new adventures this year

You can hold your breath while doing a certain skill at a certain depth but you can’t ascend while holding your breath if you have a perfect buoyancy and trim at a certain depth, for example switching regulators you can hold your breath while switching them or deploying your DSMB while maintaining depth, but you cannot ascend or descend while holding your breath

Thank you

What? No that's wrong. You are perfectly fine to hold your breath when diving... just exhale a bit when you r ascending. You can even hold a lil less than half your lungs volume from 10m... given you know how half feels like.

The most important rule is to not dive

The Angler Fish from Nemo will forever scare me from going in the water, and im from a surfing family 😭😭😭

Yeah, true, but only when you are on your way out of the water.

Another great demo! Thanks Holly!😊

I’ve been bent and this is a perfect analogy great job

I kinda like the purple chip bag more than the pink one for some reason 😂

Plastic bag on your feet...works like a charm 🙂... but not very glamourous🙁

really cool

This gave me talassophobia

Wow

Me on my way to present micro plastics to the deeps. (It's a joke)

Coool

did the chips inside stay intact?

Super interesting

Awesome demo!

this destination is worth going to, not ruined yet. that guy's not a Polynesian!, he's a white guy promoting tourism.

don't go to Similan Islands, all dead coral. lion fish killed everything.

that NZer who killed the local friendly blue grouper was horrendous. great visibility for quick shore dive.

snorkelled there surrounded by 100s turtles all queuing up for back scratches. best off beach snorkeling anywhere. see more sea life & sharks snorkelling there than scuba.

poor visibility & not much coral

Just bought that same regulator! How do you like it?

I would love to be trained from you guys

I deploy mine as you displayed here; but unfortunately there are many instructors teaching it differently. Some suggest you inflate by mouth, that way your boincey doesn't change. Some teaches as filling from the air coming from the side of the regulator. Safe dives..👌🏻🤟🏻

One of the scariest things is when your 40 feet under diving a wreck and a new diver kicks the regulator out of your mouth.

Why are you closing the analyser with your thumb? Just curiosity 😊

Imagine having a leg cramp while you are wearing one of this

OMG. NO fish life!! I was diving there in the mid &0’s and about 92. The Caribbean has been destroyed by cruise ships, big resorts and golf courses.

see you guys went with blue Bay Divers ~ outstanding dive at Julian Rocks.

Fantastic video - it brought back a lot of memories of when i did this dive 13 years ago! It might be time to go back. It is one of my favourite places I have dived. We did 2 days there and have so many amazing memories. The first descent when you are just SURROUNDED by sharks absolutely everywhere. We saw the aquarium the first time after doing the swim through of the cave. I still remember how the view took my breath away as we saw the exit of the cave just filled with sharks and even a sea turtle. I also remember swimming down to the entrance and there being wobbegongs in the trench and having to try not to kick them! Yep, definitely time to do this dive again!!

Hello

Can we breathe from our nose in the goggles you are wearing. Also without a snorkel

I’m diving there in 3 weeks 😍😍 was it very claustrophobic going through the chimneys??

You need to get off your knees, there is zero reasons to be on your knees in the water, pool or open water. tdi/sdi has some pretty good training videos that demonstrate the skills in neutral buoyancy and trim. It’s so important that we start training divers correctly for their safety and enjoyment. This is also a big segment of Dive Talk so check them out too. Have fun diving and be safe.

Great job on the video Mark. I never even heard of an Ornate Butterfly fish. We have a few different varieties of butterfly in Southeast Florida. I See Spot Fin and Four Eyed quite often and recently saw a Banded Butterfly which are pretty rare here.

And the video shows just that, well done

Amazing

But where are the mantas?

Wow this is stunning!!!!

Beautiful Dive.

Hey man, great video! I started watching your videos a couple of years ago and am excited to say that I will learn to dive soon! Best wishes from Scotland.

The mask is on very tight, much too tight

Hello There , You would consider NOT putting your finger through the spool , safety issue here , if your DSMB gets caught in a moving object (E.G : Boat/ %JetSki ) you would get injured for sure , instead holding it between your finger would be much more safer practice

"and let a little bit of air out of your BCD" *GLUG GLUG GLUG GLUG GLUG* xD

Thats why your lungs rupture if you dont breathe when ascending
