The Smart Apnea computer is the evolution of the Nemo Apneist and has become the reference computer for underwater fishermen and the most demanding freedivers. The Smart Apnea is very simple and intuitive to use and offers a large variety of functions.
Smart Apnea has an apnea mode with functions specifically dedicated to the needs of freedivers.
The Smart Apnea computer can operate in watch mode or dive mode. In watch mode you can change settings, review your logbooks with details of times and depths reached, download data to your PC and much more.
In dive mode it is possible to control depth, time, descent and ascent speed, temperature and other parameters that can be set on the surface.
Smart Apnea has a backlight function that can be activated in low ambient light.
It can record approximately 20-30 hours of dive profiles, depending on the number of dives per session and the duration of each dive, assuming a 1 second tracking interval. Using the separately sold USB clip, information can be transferred to a PC via Dive Organizer software or to a Mac via Divers' Diary software.
