It is rare to find divers these days who dive without dive computers. Multiple dives in the one day without long surface intervals cannot be done without the use of a dive computer.
Computers have improved over the years. They are considered very safe provided they are used correctly. It is important their batteries are well charged before use. If a dive computer’s battery fails during the dive then it is common practice to stop all further diving for twenty four hours.
A course on dive computers is available at professional dive shops. They are low cost and offer good value for money.
At Scuba World we provide a FREE 1 hour Suunto computer course with every dive computer we sell. If you have a Suunto computer that you purchased elsewhere, and would like to get the most out of it, enrol in a course for $99.
