    Warning suunto strongly recommends that sport divers limit their maximum depth to 40 m/130 ft or to the depth calculated by the computer based on the selected o 2 % and a maximum po 2 of 1.4 bar! Exposure to greater depths increases the risk of oxygen toxicity and decom- pression sickness. Warning d...

    Any breath hold diving results in some nitrogen build-up in the blood and other fast tissues. Due to the short time spent at depth, this build-up is generally not significant.
