Suunto D4f is a light yet robust freedive computer, that makes underwater
sports enjoyable. When diving, the D4f displays your present and maximum depth
and calculates dive time and surface intervals for you, allowing you to fully
concentrate on exploring the underwater world. Use the apnea timer to improve
your breathing technique. After the dive you can browse the details of your dive
from the logbook. The light-weight case with stainless steel bezel and mineral
crystal glass make Suunto D4f not only a trusted tool when exploring the depths,
but also looks good wearing day to day.
