Nitrox Calculator Beta v.3.2
This is a simple tool for calculating several key elements for nitrox and mixed gas (N2 and O2 only) diving.
O2 in mix:
|
% |
Depth
|
feet |
|
|
|
Air Equiv. Depth
|
|
ft |
Depth to use for calculating dive with normal (21% O2 ) dive tables |
Multiplier
|
|
% |
Difference between actual depth and equivalent depth |
Inverse Multiplier
|
|
% |
Safety margin if used with "normal" dive tables of a computer set to air |
Partial Pressure of O2
|
|
atm |
Pressure the oxygen component exherts at depth |
Partial Pressure of N2
|
|
atm |
Pressure the nitrogen component exherts at depth (including other intert gasses) |
Total air pressure at depth
|
|
psi |
Pressure exherted by all components in gas |
Number of atmospheres at depth
|
|
atm |
Pressure exherted by water and air (earth's atmosphere) on body |
Please note, there are a few issues still to be worked out with this calculator. This is to be used for instructional and informational purposes only, not as the main or only sourse of planning information for your dive.
Logs |
Annoyed with paying $25 for 25 half-pieces of paper which where pathetically useless, I long ago decided to print my own log pages. My goal was to spend as little time, thought and energy filling out my log as possible while recording as much info about the dive as possible. Since then there have been dozens of iterations. Here is a printable version of the latest log. It's a Adobe Acrobat PDF file. Print on standard or, preferably, heavy-weight paper, cut it in half and punch out the holes for a three ring binder. Of course my own log is customized to print my cert numbers, my return address, I even pre-fill the altitude, location and dates before I head out on a specific trip. If you throw enough money at me, I might customize one for you, but before bugging me, you might also want to check out dive-logs, a UK log design & printing company which allow you to cutomize your logs. Their logs are almost as nice as mine. |
