nice one

Thank you. Very professional!

Thank you! Love the explanation!

😂😂the pool noodles. Great video!

I found it weird diving with a snorkel in my mouth. Good thing I don't know how to dive deep yet. I was wondering how come it is so popular to put salt water in your mouth. Thanks for clearing it up. So 5 min break for 20min of just snorkeling, will use that advice.

Damn this is good video! Also example you used is FLAWLESS! Perfect dive.

So underrated ❤

Goliath grouper

See Air launched a kickstarter campaign was backed by 2000 backers and collected about $700K . Then it simply vanished without delivering the perks. This was just a scam ! 😡

we need more videos from you rudi...nice job in products and free diving lessons

Pure gold ❤ very insightful

#snorkelatemyhair I’m testing new gear and definitely need a haircut before diving season. Thank you for making these professional and fun videos!

Wow, as tricky amazing as Coloumbus egg 🥚 I’ll try at next open water freedive session

Excellent video

This channel is amazing. I hope you upload more videos soon. It took me a while to find this channel, may i suggest you use hashtags and maybe change the channel name being the word "free diving" first. Thank you for the knowledge

all these beautiful drawings will cover after 1-2 days. The mask is comfortable, but the nose is completely worn out

Thanks a lot sir

The fish is a grouper

Thank you for this very helpful information 👍

I have this mask in the pirate colourway, It is a phenomenal mask! Much lower volume than my mates viper that I use for spearfishing. I use the C4 for recreational Freediving but it is a truly an amazing performer

Thanks for informative video.

Excellent video

Hi send me one for free so that I can test one personally thank you

Just wow 😳 thank you Sir

Very indepth, great video. Subscribed.

Appreciate the seamless informative style.. Thank you!

Is this better then Mares Viper?

I bought it, didn’t get to use it yet, but unfortunately it only came with a paper box. Not the c3 carbon mask box shown. Buying the additional $12 case becomes even more expensive when you add shipping charges.

I have a C4 Falcon mask, and I have the silicone joint cut off, probably by the tension. I only wore the mask for a year. It's an extremely comfortable mask, but unfortunately it has that less good point in its favor. As you mention in the 6:42 minute of your video. Best Regards, from Azores - Portugal

Hey Rudi I need to ask you something about nose clip; my face is so grease, and after a couple of meter swimming the nose clip start sliding down, what do you use as a nose plug, I have been looking online but I have not found something good, thank you for you answer and for your videos they have a really backed with reality and science!

Great video, thank you! I really like the style of your videos. I think you're the Electroboom of freediving videos. If you don't know what that means: Electroboom is a very experienced and knowledgeable electrical engineer with a popular TH-cam channel about all things electrical. His style and editing are often funny and flippant, but it's obvious that he is a master of his craft and I've learned a lot watching his videos. My gf loves snorkeling and swimming under water (as long as we're in tropical warm water coral reefs), but she absolutely hates snorkels, because the mouthpieces are so uncomfortable for her that she'd rather just have a mask and hold her breath to peek down at the coral and the fishes. It sounds exhausing - I can comfortably float around the reef's edge for hours breathing through my snorkel and have enough energy left to dive down and follow the turtle or find the hidden crayfish, while she's basically doing breathhold after breathhold at the surface. I'll see if I can find her a snorkel with a softer and narrower mouthpiece to see if that suits her. Is there anything you'd recommend?

I was just talking about the inefficiency of breathing up through a snorkel too! It is about a foot of dead space which means air that is not usable by the human body (I.e. exhaled CO2 sitting in the snorkel tube at end exhalation)! Glad to see my thinking was in the right direction! Thank you!!

Fantastic explanation! I love how you break down the steps but then seamlessly put them together with the video to show it. I found myself trying to think of each step as I’m doing my entry. The slow motion video with each description is so helpful. Thank you so much!!

Oh no.. I have been doing it all wrong. I keep the mouthpiece when I dive

Can't believe this has less than 1k views. It gives me River Monster feels and I like it

Combining the two socks is what i was thinking during one of the other videos. I thought c4 should enhance the zero socks with a sewn layer of dyn material on the bottom of the sole.

Did you have to burn the film off and use toothpaste to prep it?

🤔👍👌🙏

Muito bom!

Great vid, another important I would say VERY important aspect of this is that God forbid the diver pass out ( shallow water blackout or similar ) if the snorkel is out of the mouth more than likely the mouth of the diver will be shut thus preventing water to rush into your lungs. NOW what happens if the diver pass out with the snorkel in his mouth ? The snorkel will literally facilitate water rushing to your lungs ! VERY dangerous, I would say is the most dangerous aspect of diving with the snorkel in the mouth.

And I was making/using pbc home made snorkels in Cuba ! Thanks

I just came across your channel and obviously I just subscribed. Tons of great info that I will implement this summer, thanks a million for not just your teaching but for the way you deliver it 😎 .. Googled you as well did not know you trained several world record holder free divers ! Needless to say when I heard the accent I was like “this guy is Cuban” and Yeap Cienfueguero ! I’m from Santiago de Cuba. Anyhow I’ll watch and pay close attention to your vids and teaching. Thanks

man, thats a very good video!

I really appreciate you for taking the time to explain the entry technique. It helped me a lot, I had no forward momentum and tend to stop as I was about to dive. Thankyou! Subscribed.

Really excellent explanations!

Hi Rudi and David 🙂 Thank you so much for producing and sharing this. I still use the breathing you taught me, Rudi, on the FREE Advanced Freediver course but this is sooo helpful in breaking it down so practice each step separately. THANKS.

Best visuel explanation I have seen

Rudy, these are GREAT videos, the whole freedive community should watch these. Keep the videos coming.
