Decompression meter firmfare calculates theoretical tissue saturation with inert gases based on a mathematical model. This model was made thanks to a variety of experimental data with the latest decompression theory developments. Nevetherless, using the dive computer, as well as decompression tables cannot guarantee complete protection against Decompression Decease (DD). Each diver has his own physiology that changes from day to day. None of mechanisms can foresee response of your body to any dive profile.

• Never dive deeper than dive limit set by safe Oxygen Partial Pressure!
• Never breach decompression procedures!
• Never dive deeper the limit you are certified to!
• Always study local diving conditions and depths where you are planning to dive!
