NEMO SPORT DIVE COMPUTER Congratulations! NEMO SPORT is a mobile dive computer for underwater diving that measures depth during dives and, based on the measured values, calculates and displays a variety of dive data, including such critical data as a diver's body oxygen level and the level of nitrogen that has dissolved into the diver's body. In this manual you will find all the instructions for its use. Mares thanks you for your choice and urges you to always practice safe and responsible diving.
Dive Computer NEMO Nemo SPORT sport WARNING The safety of a dive can only be increased through adequate preparation and training.
