Dive Log Placeholder plus SAC chart
The SAC (Surface Air Consumption) chart is a quick and easy way to calculate your SAC rate after a dive in a matter of seconds. Just use your air used, time of dive, depth of dive and cylinder type. The SAC Rate can then be plotted on our dedicated SAC log sheets to help you improve your air consumption over time.
For more detail and background on Surface Air Consumption please check out this info page.
The placeholder is made from very flexible plastic with cutouts for each hole so you do not need to open your binder to take it in and out.
