OVERVIEW
--------
DecoWeenie is a Palm-based fully-fledged decompression program that utilizes Bühlmann's decompression algorithm for mixed gas decompression on both OC and CC diving modes. It is also capable of using different deep safety stop options (GF, Pyle, GVE), as well as different input modes to describe the dive profile.
FEATURES
--------
- Open-circuit mode (OC).
- Closed-circuit mode (CC).
- OC deco on CC mode (for rebreathers with small scrubber canister).
- OC bailout on CC mode.
- Estimates OC gas consumption.
- Computes CC single fixed or multiple setpoints as well as multiple diluents.
- Uses the well-proven ZHL-16B or 16C algorithms by A.A. Bühlmann.
- Allows any gas mixture containing Helium, Oxygen, and Nitrogen.
- Optimizes the OC deco mixes gas-switch depths to minimize deco.
- Option to maximize O2 window deco stop.
- Option to skip all non-mandatory shallower stops after a "maximize O2 window" stop.
- Set your END.
- Set your ascent/descent rates.
- Calculates CNS% and OTU‚s for each single dive.
- Option to use Gradient Factor (GF) deep safety stops.
- Option to use Pyle deep safety stops.
- Option to use GVE deep safety stops.
- Option to update tissues following Pyle / GVE stops.
- Option to save tissue data for repetitive dives.
- Metric or imperial units.
- Time-to-fly (and time-to-altitude) calculations.
- Diving at altitude.
- Oxygen can be made narcotic.
- Air‰ breaks for 100% O2 OC or 1.6 CC deco setpoint.
- Option to update tissues during air breaks.
- Automatically plan a range of bail-out tables of different bottom times at same depth.
- Different conservatism modes.
- Single-Depth (square profile) or Way-Point (non-square) mode input.
- Way-Point could be used for complex cave profile or drop-off wall diving.
- Option to use alveolar water vapour pressure.
- CNS and OTU tracking.
SYSTEM REQUIREMENTS
-------------------
DecoWeenie should run on all Palm OS devices. Version 0.99 (beta) is available freely. Updated register versions require a one-time registration fee of $75. Details on how to register is available at the Mailing List website below.
MAILING LIST
------------
There has been a mailing list at: http://groups.yahoo.com/group/PalmPlanner since November, 2000, to discuss the development of DecoWeenie as well as a vehicle to distribute the updated software.
The DecoWeenie programs and manuals are in the "Files" section at the aforementioned website. It is highly encouraged for everyone to preview the registered-user manual before registration.
Postings are restricted to members only. However, membership is unrestricted which means anyone could subscribe/unsubscribe at anytime. The only delay to allow full access to the wbsite for new members would come from Yahoo.

DISCLAIMER
----------
DecoWeenie is tool mainly for experienced mixed-gas decompression divers. This is experimental program to study decompression planning process. DO NOT dive using any information generated from it!
