RESPONSIBLE COMPUTER DIVING
Since the advent of dive computers, it is a common mistake to assume that the old traditional rules of diving no
longer apply, but the truth is just the opposite. Before you dive using your Data100, keep these basic rules in
mind:
• Plan each dive, and dive your plan - Your computer was not designed to make decisions for you, only to
provide you with the information you need to make responsible decisions for yourself. This begins with a dive
plan that will help you avoid a low air or decompression situation.
• Do not plan any dive that exceeds your training or experience level.
• Inspect your computer before every dive - If it shows any signs of damage or abnormal function, DO
NOT dive with it until it has received factory service.
• Make your deepest dive first - When making repetitive dives, it is imperative to ensure that each consecu-
tive dive is shallower than the one before. This will allow your body's slower tissues to continue outgassing
nitrogen.
• Make the deepest part of your dive first, and gradually work your way to the surface using a
“staircase” profile - The ability to perform multilevel diving is one of the most important contributions of a
dive computer, and you should take advantage of it. It will increase your bottom time and at the same time
decrease your risk of decompression sickness.
• Ascend slowly by following an ascent line whenever possible, or by ascending diagonally toward
the surface - Watch the Variable Ascent Rate Indicator while you ascend, and keep your ascent as slow as
possible.
• Make a safety stop at 15-20 feet (5-6.5 meters) at the end of every dive - A safety stop of as little as 5
minutes has been shown to have a dramatic effect on the bubble formation in divers. It's important. Don't
forget it.
