36-Hour Log Book Memory allows you to store a lot of information about your dive and the best computers boast 36 hours of continuous recording. Memory is important. You'll need a computer with sufficient memory to cover you for your dive period. The Vytec can store up to 36 hours of detailed dive information that can be either viewed on the screen, or downloaded to your PC. In fact, the Vytec even allows you to set the sampling rate (the interval it takes a reading, either 60, 30, 20 or 10 seconds).
