The same performance you've come to expect in the popular D4i scuba computer is now available in a version dedicated solely to freediving. The Suunto D4f Freediving Computer displays present and maximum depth of your dives, and logs them in its electronic logbook history. This computer also calculates dive time and surface intervals, allowing you to perform better by getting sufficient breathe-up time between dives. The apnea timer function is great when training and diving, and with the electroluminescent backlight, you'll be able to see your dive data in any conditions.
