Equipment Checklist: The app includes a complete checklist with all the essential gear for a safe dive. From the regulator to the wetsuit, users can ensure they don't forget any equipment before getting into the water. The design of the Diving Calculator is visually appealing, using blue tones that evoke the underwater environment.
