Static Apnea, well sort of larr... I did use my Mundial Competition but stayed between 1.5 to a max of 1.9m for 1.32 min.
But I must say I am very impressed at the sampling rate of this D4. So I can see my entire profile of 1.32 min on every second. Not forgetting there is a graph as well.
Next trip, I've got to see how deep this thing will record.
