- How much weight do we need to compensate for a full vs empty Aluminum Alloy SCUBA tank such that we do not float away at the end of a dive but rather come up slowly at a safe rate of ascent, ideally making a safety stop at 20 - 15 ft for 3 minutes.
Also we look at the Steel tank and the buoyancy of the steel tank full vs empty.

Gurl is free flowin’
Yes, her reg was, repaired after the even :) ty
Thank you Ron, love your work mate.
My pleasure Uncle Milton.
I can Vouch for the AL80 Buoyancy. When I did a Lake Cleanup I used my Aqua Lung Omni Custom BCD for the First time. Once I got there I found out Trim Pockets were Extra. Used a 7/5mm FS in 55F Water. Ok in the beginning of the dive. Got down to around 1500, Had trouble staying down. Hit about 1200, Floating with an Empty BCD. Went back to the shop 2 days later. Spoke to the Owner. Who was Surprised the Omni didn't include Trim Pockets for the $800 Cost. He sold me a set. Switched some of the Weights he sold me. I should be good now for the next Cleanup.
I realize there are some Lessons to be had here. As I was Certified Aug 2023. Check the Gear before heading out. And to Test the Gear in a Pool. Which unfortunately I wasn't able to do. I swim at a College Pool. They may not allow me to. They do allow me to do Breatholds the length of the Pool along the floor. Max Depth 13 1/2 Feet. Roughly a 90 Foot run each time.
Great video, simply explained 👏🏾 👌🏾
Thanks :)
I love your experiments
Not to mention my scientific assistant ;)
I agree with fluffyhamster! I just completed my advanced open water cert. , and the instructors did not let me use my steel tanks. Just as it was proven in the video at about 1500 psi I was starting to float and had to fight to stay a depth. When it came time to do our deep dives they did not want an uncontrolled ascent I was so overweight if I stopped swimming I sank. 100 ft down this is not a pleasant situation to be in.
I use steel tanks, with a 6 pound tank weight for my back inflation bcd. Keeps me vertical on the surface.
Great video, but how does she allow her octo free flow for half of the video.
hello Bill and I do agree with you ... we do have a reason which is not great but ... I have several videos with her diving and alternate properly secured, in this video it had a slight free flow (needed service after Covid lock down for 2 years) and rather than defer video, we hung it such that the bubbles would not take away from video content. Many thanks for your comment, stay well and she now has Octopus free flow sorted and Alternate clipped on as it should be! Thanks for catching that!
I think you sacrifice the light weight of the aluminum anyways by using weights so that's cool I will just stick with steel.
While I do agree, i recently tried to hydro test a steel on a caribbean island and cannot get it done to DOT regulation / Standards … I love my steel tanks, but this has now become a serious problem and issue. My point simply being that whilst i prefer steel, depending on where it is used and the divers live, they may have only 5 yeas use before having to ship back to USA for hydro. Thanks for your comment joejeans.
Nice experiment. Your rescue diver needs to secure her octopus.
Thanks for your message, no argument at all on the alternate and I agree and she does also, in fact I have several videos with her diving and alternate properly secured, in this video it had a slight free flow (needed service after Covid lock down for 2 years) and rather than defer video, we hung it such that the bubbles would not take away from video content. Many thanks for your comment on our experiment and documenting same :)
hey ron
Hey Dredd ... good to see you!
You got anew sub
she did :)
Great video but the free flow octopus reg is so distracting.
Def I agree with you Robert, lesson learned. Thanks for your comment, Note to self well made,
Were they empty or full
at the start they wee full and the last one the tank was at 500psi (so empty)
tu est allé longtemps a l'école pour nous sortir cette vidéo >??? déjà, utilise le Bar, le Kilo et le centimètre, sort un peu de ton trou...
thanks for your comment, vey inspiring :) stay well!
This is someone that knows what's he is talking about
Thanks .... 40 years of diving and teaching probably had something to do with that :)
Better take care of your octopus 🤙
We did change the seat on that second stage and its all good again, thanks for that :)
