Recreationel Dive Planner Helper 1.2.1
This program allows you to plan for repetitive dives with the least amount of surface interval time.
You can reduce your intervals by planning your dives for either a shallower depth or shorter dive time and your new surface intervals are displayed immediately.
Even if you use a submersible dive computer, you can increase your safety margin by using this program in conjunction with your dive computer. More importantly you can plan for your dives before you begin your dive trip.
