This is excellent and very detailed! I really like the one-handed number method for the reasons that you say you teach it. A few more that I thought of: "Out of Air" (throat slash); "Low on air" (fist to chest); "Come up a little" (gesture with open palm, fingers up and down); "Level off" (flat hand left to right ); "Cut" (scissors motion) ;"Line" or "rope" (fingers crossed); "computer stop/deco is clear" (wipe computer face with palm); "turn around" (spin vertical finger); "A little" or "small" (thumb almost touching index finger); "Cramp" (fist bumping affected area); and alternative "stop" or "hold" (vertical fist).

bro only one ear pops what do i do iom 14 and im about to start diving soon

Which brand of condom do you prefer?

Never, thanks for your video. When I make multiple dives in a day I breath pure oxygen for few minutes and it really helps to expel nitrogen and reduces risk of bends.

Solid recommendations!! Thank you 🙏

Hi, For a neck circumference of 40 cm, it's recommended to choose a seal that allows for approximately 1.5-2 cm of stretch for a comfortable fit. should cut it down to 37cm neck seal circumfence?

Thank you sir

I have sinus problem but i did surgery and cleared the issue. I do nasal rinse to avoid congestion due to cold which is effective. Am i eligible to learn scuba diving?

Incomplete example

DIN. I'm in Australia and it's rare. But I always have an adapter with me, so if im hiring it's no issue. Best of both worlds.

Are you supposed to put the wet suit over the rash protector suit ?

A very nice video that covers a lot of details and differences between the two!

Perfect thanks. Great video

Thanks for the video, you simply answered a few of my questions.

Can I wear wetsuit and dive gloves and dive hood and dive boots and dive fins dive mask and scuba tank and bcd and regulator to breath from scuba regulator for warm water diving

so many points missing here!! but you did caving without dry?

I dislike frog kick. I don't more anywhere. Flutter is superior. I use the same amount of air as the drivers using frog.

Great Video👍

Dude, get Mares MV so much easier.

Excellent! thanks!

Happy to learn about the modifications, i've actually tried to use the valsalva multiple times before but it never felt really effective so i'll try them for sure and see if it works better.

Do you have an updated video that shows when you're making turns underwater and what to do with your compass?

In the pool demo, the feet stay in the plane of the body. The knees are displaced downwards. In the depth demo, the feet are way above the plane of the body, sometimes with the knees bent 90 deg vertically. Which is correct? [I think the first one.]

is it normal if i have to do toynbee twice? the first time, my ears get clogged, then theyre free again but they crack everytime

Cressi is was of those, like all italian brand, they are much smaller then you are used to, so don't feel ashamed, because if you wear Large you would need to buy XL. I guess it's because italian people are different build then rest of Europe. It's even still like this, so we still say 1,8m is standard height while in Italy it's 1,75. Well it's what we told in rest of Europe. But it's a kind of fact in Europe, those in the north are mostly taller then those in the south. 😯

Excellent video!!

Curious that you said steel tanks are heavier. I'm interested to hear what this is based on, because apples-to-apples capacity-wise, steel is lighter out of the water. The link in your video doesn't work and I couldn't find anything on your website about different tanks, so here's some info from Faber and Thunderbird: Al80 - 31.9 lbs LP85 - 31.2 lbs HP80 - 28.3 lbs

I prefer a stiletto knife with one straight edge and one jagged edge, they are one of the most versatile knives for diving. Can be used for everything from gutting a fish to sawing rope.

Aluminum tanks are more heavy than comparable steel on land but lighter in the water when empty. So you need more lead with aluminum that you have to carry in addition to the heavier aluminum tanks. Except for stage tanks where aluminum is mandatory i can not think of any situation where aluminum is the prefferable choice. The medium 12 liter steel at 232 bar at around 13 kg empty is a real nice setup with more air to breathe and less weight to carry than your 80 cft aluminium. It has much less impact on the trim.

I also carry a folding knife attached to a bolt snap. Suggestion, an ALL serrated blade cuts line better. If you wear gloves make sure you can open your knife with your gloves on. Also, don't look like a Christmas tree (potential entanglement points). Only carry the items on you that you might need for that dive.

im going to choose 12Liter Steel cylinders with max 200 bar, they are lighter than the 230 bar cylinders and nearly balanced when they are empty. On land less heavy than aluminum cylinders and under water also good to handle if it comes to sidemount. Will use them in fresh water with a drysuit.

Can I strap over 40lbs on a small woman in a dry suit she isn't certified on in pockets that can't be ditched? Just curious

Don't forget the possibility to use heated undergarment, like vest gloves or whole suit! I use separated heated gloves and vest (Vest on medium and gloves on full). Also the big advantage of using a drysuit: You can put at home the undersuit, so no bare body exposure to the weather elements on the dive site!

Hey thanks for showing this, it is just what I needed to see. Do you mind if I use the video with full credits to you? I just want to remind a flat earther that air has weight.

Not sure why you decided ratchet strap is must have for divers out of all other gear, 99% of divers will never buy tanks, and tying tanks to each other does not help, my 2x12 slide in my trunk if I don't use rubber mat or something to hold them, dive light is much better choice than strap

You are first instructor in history of diving that did not recomend having spare mask on dive, if you have it with you, there is no point of leaving it on boat take it to dive, its not extra thing, its most important peace of gear

Enough detail to point out what is missing (ex. description of how second stage operates). Some misleading information (ex. Unbalanced first stage). Regulator first stage types. Balanced (Diaphrgam. balanced Piston) Unbalanced (Flow by or Unbalanced Piston). Missing Balanced vs Unbalanced second stages,

I bought your navigation course was waiting for the password so I can log on but never got it,

Great video. Make sure you practice DSMB deployment often. Don’t wait until you need to deploy. I am a FL diver and I deploy my DSMB on every spring dive as it typically is a very benign environment to practice in. I fell very comfortable deploying on drift dives along the coast. I actually carry two DSMBs; a large DSMB that can easily be inflated on the surface and a smaller DSMB that I can easily deploy at depth. Also, I would add signaling devices- whistle and mirror. I always have a small flashlight hooked to my BP/W.

Heard DIN is less likely to freeze in cold water.

Just freedove. Nose started bleeding. I should train a bit first

- Don't get too big of a dSMB. The bigger the dSMB, the harder it is to keep it upright. Narrow and long is better than wide and/or short. For durability it's best to get one with both sides stitched. - Most spools need a lot of preparation before they're suitable for use underwater. If your spool is overwound, you need to remove a lot of line to clear the holes enough so you can thread the line through. Make a large loop in your line with two small loops at the side and the top so you can easily untangle it. - Have more than one cutting device, ideally two different types of cutting devices. The EezyCut Trilobite is by far the best and most versatile cutting device available at the moment, but it's limited in the size of line or rope you can cut. Having an additional serrated edge blade or a set of trauma shears on you is a good idea. I personally carry four cutting devices: 2 Trilobites, a serrated edge folding knife, and a set of trauma shears. - In addition to a backup mask, bring some spare mask straps to the dive site. Silicone straps can develop small nicks that can quickly turn into a tear. In addition I'd recommend always having a small dive light on your harness, even during day dives. They're great to peek into small holes and crevices, and to bring back color at depth. Should you become lost at sea, they're also great for signalling, and of course they can function as a backup light during night or cave dives.

It continues to amaze me how pervasive the "steel tanks are heavier than equivalent aluminum tanks" myth is.

A+ info

Din

I am considering upgrading to a new regulator. I figured a yoke would be my best option, but it does seem to be a bit of a hassle.

I never would buy a Yoke Regulator. DIN is just better anyway. Why would i clamp something if i can srew it?

Do you dive dry? What was the final straw that made you choose drysuit diving?
