DataTrans Plus
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 DataTrans Plus, keep these ba-
sic 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 con-
secutive dive is shallower than the one before. This will allow your body's slower tissues to continue out-
gassing 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 to-
ward the surface - Watch the Variable Ascent Rate Iindicator closely while you ascend, and keep it in
the green zone as much as possible.
• Make a safety stop at 15-20 feet (4.5-6 m) 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.
