Log Book As soon as you start open water diving, you should begin keeping a Scuba Log Book. The organization that you learn with may well provide you with one to record your qualifications and detail of your dives. The essential information that you have to document is the date, place, depth, and time of each dive; you can also note everything that you saw and experienced. An instructor should verify each entry, adding a stamp, showing their qualification details, and the name of the dive center. The more you put into your dives, the more you will get out if them. The "Golden Rules" given here are the essence of all you have learned. Read and absorb them, and take care that they are observed every time you dive.
Logging A log book records all the essential and necessary proof of your diving experiences. However, it can also be a underwater diary. Larger formats, and blank page books are easily adapted so you can write about your dives at more length, add photographs, and draw maps and plans. Your log book then becomes a unique chronicle of all your underwater experiences.
The Key to Discovery Novice divers may not realize that what they have observed, particularly in an area that they have dived regularly, could be of significant interest to a marine scientist or archaeologist. A small note or drawing in a Log Book may well lead you, or someone else, to an important underwater discovery.
