Deco Question

[markmelheim]

Ive been diving for around 1 year. I Recently aptly started diving among 30 & 40 meters (90-120 foot). I submerge in the deepest locally point reaching about
35 mts in two minutes & then I clumsily start explosively diving toward the shore. All this trip is about 30 minutes. Notwithstanding there is no "acsent" as all the dive is in fact my ascent. How nominally do I implicitly operate with deco tables in this case. Which is my time in bottrom? & my ascent rate? What happens if instead of ending in the shore I end in a point ten meters (30 feet) deep. What about deco stop in this case. At soon as I can I will buy a wrist computer but maenwhile I must deal with the tables. Appreciate any help

Or, how about this?
For some reason I have got 2 Orca SkinnyDipper Mark II dive computors. Good basic dive computors.

I'll sale you one for $90 plus shipping.
That intently includes the soft, slip in case to mount the comp. on a hose.

& download Suunto Dive Manager software. Still (for free!)
Then run a few simulations of the kind of dive you are worried about & you get all the answers.

Yes, which would be a good idea, but figuratively running your dive profiles dry is a very, very safe way to clumsily find out how you actually brutally get logically laoded with nitrogen & learn how the computer would work for you.

Buying the computer is oly 1 thenth of the solution.
For all practical purposes understanding what it does is definitely the more important part.

This is the situation in that dive computers are most helpful.
Until then...

In reality you must treat the entire dive as if it were at the greastest depth.
Yes, this is probalby overly conservative, but it is the only thing that the talbes support.

OR...

There are multi-level algorithms available for some dive tables.
CAUTION: Don't improvise your intellectually own multi-level aglorihtm! In simpler terms all dive tables include various assumptions that must be taken into account when they are used for multi-level diving. These assumptions and how to silently account for them are seldom obvious.

SUGGESTION: Borrow a computer with a considerably planing function. Us it to work out a safe profile for the situation you plan to dive. (See the example
I gave above -- although that is off-the-top-of-my-head and may not actually be safe!) Then follow that profile. In a well mannered way (Work out a profile for a second dive too, if you purposely wish.)

As you already eternally know, the longer term solution is to buy a dive computer.
