The whole point of diving is to have a good time. There’s absolutely no reason why your pre-dive checks shouldn't be an enjoyable experience as well. The pre dive safety check is the start of the fun and shouldn't take long to complete!

B. BCD inflate does it hold air? Dumps check all of them do they deflate?

W. Weight system weight belt, integrated? On or installed correctly?

R. Releases check how they work squeeze or pinch?

A. AIR On? Do the smell and taste test, breathe both second stages and check for any SPG fluctuation?

F. Final Check - have you got everything? Let's go diving...

How to Complete a Scuba Descent and Ascent


A proper descent takes only seconds and ensures that a diver is properly prepared before going underwater.

Signal to buddy ready to go
Orientation buddy, shot line, wall
Regulator second stage should now be in place
Time Check dive computer is on
Elevate LPI and Dry suit dump
Descend slowly with buddy and equalise your air spaces, maintain your buoyancy

Floating on the surface before a dive is exciting! Whether the water is clear enough to see angelfish 10 metres below or so murky that the bottom isn't visible, most divers can't wait to descend and start diving. Filled with happy anticipation, it is tempting for a diver to skip pre-dive checks and safety protocols in a rush to get underwater. However, if you have ever accidentally descended with a snorkel in your mouth, you know that taking the time to follow safety procedures is well worth a few extra moments on the surface.


One of the first things golden rules in scuba is that you should never hold your breath, another one is that we should always slowly ascent from every dive, thus the importance of a safe ascent from depths

Signal Give the clear ready to start ascending signal (thumb up hand signal) and receive a confirmation from all divers that they are aware the dive is ending. Signal

Time Look at the time indicated on your dive computer to make sure the No-decompression (No Stop) limit has not been exceeded. If exceeded prepare to make decompression stops at recommended depths (follow the directions given by your computer) and signal to your buddy diver for a confirmation. Time and fully complete your safety stop.
Ascend Look up and make sure there’s a direct path to the surface. Search for obstacles (like boats you won’t want to bonk your head on). Slowly swim to the surface remember you will need to dump expanding air from your BCD and dry suit (if applicable).
Safety Stop We break our ascent at 5 metres for 3 minutes. Counted down in minutes and we continue to the surface once the dive computers have cleared.
React Take hold of your LPI and as soon as break to the surface achieve positive buoyancy by adding air to your BCD,check your buddy and signal surface cover that you are okay?
