Depth - Time Chart

[Sjlira]

Hi everyone! I was trying to find a chart that could broadly correlate time and depth so that one could estimate how long would it take to reach and surface an specific depth. Does anyone have information about this so i could make the chart?

Let us all consider is a broad correlation of average Time/depth to make estimations. This chart won´t give exact numbers, but at least some ideas for training.

Cheers!

Honestly I have wondered the same and all I did was youtube the depth I questioned. Then just watch people dive that depth and see how long it took them.

maybe i can help here...
however some of the values must be from doing safety protocols to another freedivier [some of the depth are arround 10m but took longue], yet:
this are the data stored in my diving computer
hope that those can be of help to you

It is very dependent on your own speed and really says nothing. Some people are comfortable doing 20m in 40 seconds, others do it in 60 seconds and feel the same way at the surface.
0.8m/s seems to be the sweet spot for me.

after reviewing those data i managed to do a table... [not necesarely valid for all freedivers!!!]
to be mentioned that this is an personal CWT experience - based table
i dived untill 28 m of depth and because of that, the 30m and 32m grid, are deduced by logic...
in that table i put the depths from 10 to 10m AND the ussual AIDA 2,3 and 4* requirements...

from bellow 32m, perhaps other freedivers better than me, can do the trick

 

[Tommy_R]

Monofin or bifin ?
a very rough estimation is 1 m/s so you can calculate your time. Shallower dives tend to be a bit slower. Bifin dives also.

monofin...sorry i forgot to mention...my bad
in fact the dives where made with bifins and monofins
but shurelly the ones bellow 20m was made with monofin!
