It is good practice as a diver to perform a safety stop at the end of every dive even if your calculations or your computer tell you it is safe to ascend.

Generally I’ll spend five minutes at five meters after a twenty meter dive but sometimes it seems that that five minutes takes longer than the entire dive.

Picture this; it’s gloomy, the visibility is mediocre, your are hanging under a boat in mid water five kilometres off-shore, this is South Australia and rare as it is, divers have been lost doing just this.

Even so I would not give up diving for anything but still those five minutes tend to be the longest five minutes of my life.
