Comment on WEIGHT A MINUTE! ESTIMATING WEIGHTS FOR SCUBA DIVING IN A MINUTE by Tobi1kanoby

Hi Dave
I see what you’re saying, the numbers orders got mixed up here and I will fix it shortly.
If you use a 7 mm wet suit, add 4-5 lbs or 2 KG to your 10% body weight worth of led,
for example, if you were to weigh 70kg you’d have to carry about 9kgs (7+2). this is a fresh water calculation
you would then have to add weight due to water salinity as mentioned in the next chart.
You may also simply multiply the 1st chart result by 1.03 to be more precise.
Remember, this is an estimation of the weights you’ll need, and you will still need to complete a buoyancy check prior to diving to fine tune your results.
Hope this helps.
Let me know if you need further instruction
Tobi

Your 7mm suit calulation is not clear and very confusing.
please explain.

Also was the first table for fresh water and then add the weight from the salt water table? Or was the salt water table for suit weighting a “stand alone” chart??

PLease clarify

Thank You Chelsea for your wise comment.
The whole purpose of fin pivot is to demonstrate buoyancy control using nothing but your lungs. You cannot expect new divers to learn skills in mid water. These skills are simple steps towards gaining control and confidence. Your instructor should have said you cannot use your hands, you’re right about that, but from my experience, where I work and dive, these are standards. Once again, PPB is another program that, if done correctly improve divers skills by practicing the basics rather than swimming all over the place.
Yes, bad buoyancy is one of our biggest concerns as dive instructors, and unfortunately I must admit, to often I see certified divers with now buoyancy skills at all.
As I mentioned in earlier posts, I’m working on adding more videos to these tutorials, that I hope will clear some misconceptions.

Hi Jodie,
a minor nose bleed can happen from time to time, and I’m not that concerned about it , but I’m more worried about your chest, and I’d definitely encourage you to see a physician before you continue diving. As I’m not a dive physician . Not me, nor any dive professional should take responsibility for your health giving you these kinds of advices.

Hi Barney, Thanks for the comment, I’m sorry I couldn’t replay earlier, I’m about to have my first son any day now and we’re awfully busy here….
i plan on adding more content in the next few weeks, and yes, more videos.
I totally agree with the wrong messages sent by the dive industry’s videos, showing diver wearing gloves in tropical waters, touching the bottom, sculling and overall setting bad examples for future divers.
thanks again for your comments, keep on the good work.
p.s if you wish to contribute to the website ( images, your own videos or stories) let me know,
Tobi

I suffer from reverse block after I Ascend, each dive. It causes me no pain and I don’t realise I have it until ont he surface,until my buddy makesme aware I have a little nose bleed.

I find when I am Ascending I get quite a bit of flem on my chest riseing up into my throat , I have never dived with a cold nore would I.

Can anyone think of a cause for this or give me and Advice please. This has not stopedme from diving as I have just completed my Advanced course.

Here’s whats wrong: We begin learning to dive on our knees and overweighted (that’s NEGATIVE BUOYANCY). Then we learn to FIN PIVOT (THAT’S NEGATIVE BUOYANCY) because touching is touching. Our instructor never tells us not to use our hands because he knows we will see him/her scull and he/she doesn’t want to identify any flaws they have. THEN we are told that the PRIZE is NEUTRAL BUOYANCY and the path to that is PPBuoyancy(the same fox who stole the chickens will now guard the coop) don’t do as we do______do as we say and just keep the dollars coming. LOTS OF REHITORIC follows:cheap talk heaped upon cheap talk from self appointed experts while most of the community bobs up and down while flailing with their hands and throwing more doallars into toys that never seem to make us better divers. WE NEED VISUALS! We need more buoyancy experts who aren’t afraid to show moving pictures of their skills so we can decide if we want to copy them.DON’T TELL ME____SHOW ME!!!

I think that the hanging console in the photo above sends the wrong message. Images really do make a difference in mentoring diving skills in general and buoyancy skills in particular. We need to see more visuals….PREFERABLY MOVING PICTURES! I’ve seen this still photo, on line, of some guy hovering next to a set of doubles, like on a safety stop, with just the hose to the 2nd stage connecting him to these tanks. It looks spectacular until you stop to consult some common sense. FIRST he’s vertical and that’s the wrong message ________ then don’t you just wish this was a movie rather than an image of 1/250th of a second? I think we need less rehitoric and less reading from prepared agency authored outlines and more MOVIES! I want to see what a buoyancy expert looks like underwater so I can decide if I think he/she is really who I want to imitate. Of course video can be edited too which makes you wonder why there’s so much sculling in the videos offered by some huge training agencies. I guess that’s what they meen by how the world learns to dive?
