Hello all, I as wondering what you think is the important aspect of your freediving watch for learning more. Do you set your depth and time to a specific setting and go by that, is it the surface interval time that is most important (set to say 2 minutes), is it the depth alarm noise you hear that tells you how deep you are or is it the time alarm that tells you to head for the surface. I am just curious as to how you all set up your timepieces for freediving and what it is that is most important when using a watch, thanks all. I have a Suunto D4 by the way.
