Advanced Open Water Deep Dive

Advanced Open Water Deep Dive is one of the required dives needed on most recreational diving certifying agencies to gain AOW Certification. On this dive Lyell will demonstrate the effects of pressure on compressible objects, and what the ramifications are for us as divers in terms of pressure, volume and density relationships! Diving to 100 feet brings with it a need for appropriate knowledge and skills to manage gas consumption, buoyancy, descents and ascents, air spaces and understanding non-decompression limits to be a safe diver.

I just showed my 10 year old son this as he’s learning his open water course. This is without question the best video to explain water pressure I’ve seen . Having watched the video together, I then went on to ask him pertinent questions and wow, he understood. Great job

[Bananafeller]

Great video!! Just wanted to point out that the unit for pressure on your depth vs pressure table should be ATM not ATA, as ATA is just short hand for ATM Absolute, ATA gauge doesn't make any sense.

"Listen to what the bottle sounds like"; that woke up my cat!

My Dive Master did this and it exploded in his hand on the way up. Ouch! Great stuff

Enjoyed your video. Would love more info on EAD. I'm in Bora doing OW and AOW now EAD is next. Hard to find videos that cover the same material as what's in the books, only with more info or explained differently. Trying to enhance my edu experience as I am learning. Just a suggestion for future videos.

Great experiment! It’s one thing to read about it in course materials but another to actual go and do it and see it with your own eyes. Scary to think what that would do to your lungs!

Nice filming man. Scuba diving is awesome

[yiho]

great video! what kind of knot did you use to tie the bottle to the reel? And is it easy to untie (as I assume you don't want to cut the line each time)?

[DiveVibe]

Nice rashguard! I wonder if we've been diving? I work at Jacks.

Why doesn't the water pressure crush our bodies like it crushes the water bottle in this video?

Hi! I'm Audy. Can I be your diving assistant? :)

[mynamejeff]

That’s why you don’t hold your breathe while ascending

[danielvanderblij]

Why do you always refer to imperial measures? The rest of the world use metrics!

I didn't think it was possible to make a more boring version of the padi dive training... but here we are. 😂
