If you are currently undertaking diving courses, you may be interested to learn more about DIR. DIR stands for 'Doing It Right' and is a method of scuba diving that aims to standardise diving equipment and procedures in order to help improve safety. Here's a brief overview of DIR.
A few years ago, it became fashionable to customise your dive gear, but this wide variance in setups led to many accidents, especially in emergency situations where familiarly with each other's rigging is so important. For this reason, DIR seeks to standardise the kit used by scuba divers.
Your dive harness should be made of one single length of webbing that is passed through your back-plate, buckled at your waist. QR buckles are used because they are easy to get in or out of, once you've set your harness up correctly.
There should also be five 'D' rings set at intervals around your harness as follows:
- one on each shoulder
- one on your left hip
- two on the crotch strap of the harness
When setting up your regulator, it should always come from a right-hand valve cylinder via a single long hose.
DIR dictates that you don't need large wings or double bladders. This is because you should be correctly weighted, allowing you to simply shed excess weight and resurface without having to rely on a BCD in the event of failure. Larger wings will only give more drag and reduce buoyancy.
In addition to the correct equipment configuration for safety, DIR encourages divers to keep mentally alert and physically fit so that they are able to cope with any issues that might arise during a dive.
The emphasis is placed very much on buoyancy, with minimal weight trim being used. The correct trim makes it easier for you to drop weights so that you can surface in an emergency, and also aids correct positioning and better efficiency in the water.
You will also spend much time practicing basic dive skills such as AAS donation and mask clearing. This means that everyone diving as a team will be competent and confident in the event that an incident occurs during a dive.
Another crucial safety aspect of DIR diving is having the discipline to undertake a one minute safety check before entering the water. All too often divers are keen to jump in without making sure that everything is set up and working correctly first.
DIR is all about making diving efficient and safe and therefore reducing accidents. Ask your dive instructor for more information about DIR and enjoy the wonders of the deep, safely.
