The second of my posts in 2013 on using the PADI Recreational Dive Planner focused on how to calculate the shortest surface interval. This is an important skill to use so that you can plan your days diving more efficiently. It can be scaled so that you can work out the shortest surface interval between multiple dives.

So why would you want to work out the minimum surface interval, instead of just taking the longest one you can? Well there are several reasons, the most common is half day boat trips where you only have the boat for a short period of time and you are wanting to get as much diving done as possible.

So I have made a video showing you how to use the PADI RDP.

You can also follow along with this video if you are using the eRDPml

Let me state that you must receive formal training from one of the many dive organisations before attempting a dive. Without formal training you risk injuring yourself. Please get training before attempting anything you have read or seen in this post. I will not be held responsible for you attempting to use the methods contained in this post. The following post is for illustration purposes only.
