Info The "Ultimate" wing lift calculator :)

[selytch]

Hello everybody,
I've been puzzled for some time picking the right wing and made this small excel spreadsheet to assist me. It helps choosing the right lift for your wing/BC, picking enough _and_not_more_ lead and shows your buoyancy at the various stages of dive.
Start with section 1 and see how the table changes and the required lift/amount of weight are displayed in section 2.
Post your feedback/suggestions here or pm/email me.
Enjoy!

PS. IMHO this may be helpful not only to novice divers but also to advanced ones.

Cannot open on MAC. I need excel....anyway to email it or cut, copy and paste it here? Interested in reading it. Thanks.

What is the "above water" value represent? That's not clear to me. Neither is head weight.

It has to be in excel or similar spreadsheet - there are dynamic calculation.
You can download openoffice (openoffice.org), I believe they have mac version as well.

When you are on the surface a part of your body - usually head - sticks out. This way you can breath not compressed air and talk to your buddies )

When the head is above the surface it contributes to negative buoyancy. Since average head weighs ~10# that's how much compensation we need to keep it above surface.

BTW, I just uploaded an updated version, which can calculate lift for both weight integrated (lead on rig) and non-integrated (weight belt) BC. There are some substancial differences between the two.

Looks like a great tool! Can't wait to try it out.

Aren't regs something like -2 lbs? Didn't see that reflected. [Obviously can just add to tank, but might be nice to have in there.]

Also, any suggestions for calculating exposure suit lift at depth? I had no idea what to put in this cell for my 7 mm wetsuit and 6/4 mm hooded vest. Thanks!
