MultiDeco is an extention of the V-Planner program. MultiDeco brings several decompression models and methods into one program.
Please note - this program is made with the experienced and technical diver in mind. If you're relatively new to diving, you may find this program difficult to use. You're expected to know the theory behind the diving practices and procedures used here.
********* WARNING / DISCLAIMER *********
  The author and HHS Software Corp do not warrant that this program accurately reflects the Varying Permeability Model algorithms, or that it won't get you bent or dead, or that it will produce safe, reliable results. This dive schedule is experimental and you use it at your own risk. Diving in general is fraught with risk, and decompression diving adds significantly more risk. Deep diving utilizing multiple gasses, including helium, or rebreathers is about as risky as it gets. V-Planner and the decompression schedules it produces are tools for experienced mixed-gas decompression divers ONLY. If you have not been properly trained in mixed-gas decompression diving by an internationally recognized technical certification agency and/or don't have a firm handle on decompression planning and mixed-gas diving, then DO NOT USE THIS SOFTWARE.
