Open water dives: you must complete four open water dives in which you demonstrate your skills. See ‘PADI open water tests’ below for more. In choosing a course, firstly, make sure your dive centre is certified by PADI . There are centres all over the world that advertise the PADI Open Water Diver course but which aren’t actually certified.
Available on the RDP Table: if you are planning a dive in cold water or under conditions that might be strenuous, plan the dive assuming the depth is 4 meters deeper than actual. Refer: RDP/eRDPML Instructions for Use booklet.
Case scenario: a group of advanced Open Water Divers plans to make two dives. The 1 st dive is on a reef in 22meters of water for 20minutes. The group has an surface interval of 1hour then have a 2 nd dive is on s wreck in 18meters of water with a planned bottom time for 30minutes. b.
The RDP has three parts, Tables 1, 2 and 3. Table 1 tells you the maximum amount of time you can stay at a certain depth on your first dive, and it tells you how much nitrogen you have in your body after a dive (letters A through Z, Z meaning you have plenty of it, A very little).

The Recreational Dive Planner (or RDP) is a decompression table in which no-stop time underwater is calculated. The RDP was developed by DSAT and was the first dive table developed exclusively for no-stop recreational diving.

How Many Scuba Dives Can You Do In A Day? Technically there is no specified limit on the number of times that you can dive in one day. The number of times that you can safely scuba dive in one day is dependent on how much nitrogen your body will take in. Nitrogen is harmful to divers.
Of course, a surface interval is the period of time that a diver stays out of the water between two dives. During this time, the nitrogen absorbed during the first dive will be released from a diver's body. After 24 hours all the residual nitrogen is considered to be off-gassed.
The general rule that seems to be widely agreed upon is that you should wait 12 hours after a single no-decompression dive, 18 hours after multiple dives or multiple days of diving and at least 24 hours after dives requiring decompression stops.
If you don't know your body well enough to know if you can handle doing three dives in a day safely, don't do it. If you can't handle planning repetitive dives then you need to go back through your dive planing materials from open water.
In choosing a course, firstly, make sure your dive centre is certified by PADI . There are centres all over the world that advertise the PADI Open Water Diver course but which aren’t actually certified. They will happily take your money and while you probably will learn to dive, you won’t be certified. Secondly, if you’re a nervous diver, try ...
You must complete four open water dives in order to pass the course. Dive 1 will orientate you, get you comfortable with the scuba gear and test a few of the above skills. Dives 2 and 3 will rigorously test the above skills while Dive 4 is usually a more relaxed affair allowing you to use and enjoy your newly developed skills.
Clear snorkel on ascent by exhaling sharply and continue breathing without lifting face from water

This is reviewed in a final test in which you must score 75% or higher . If you fail, you can retake the test. See ‘PADI test questions’ below for more.
Confined water dives: this is usually done in a pool or shallow water in the sea with the aim of teaching you basic scuba skills. See ‘PADI confined water tests’ below for more. Open water dives: you must complete four open water dives in which you demonstrate your skills. See ‘PADI open water tests’ below for more.
If you feel panic rising, just continue breathing. If you can’t think through your flooded mask, just keep breathing. If you want to shoot up to the top, just keep breathing.
