PADI Divemaster Certification Practice Exam

Which of the following statements about dive computer technology is inaccurate?

1. Most models require a battery replacement annually.

2. Dive computers cannot be used for planning multiple dives in a day.

3. Advanced models may track multiple gases for technical divers.

4. Many models log dives for future reference.

The correct answer is: Dive computers cannot be used for planning multiple dives in a day.

The statement that dive computers cannot be used for planning multiple dives in a day is inaccurate because dive computers are specifically designed to aid divers in both planning and executing dives, including multiple dives within a single day. Many modern dive computers allow divers to input various parameters and calculate necessary information such as no-decompression limits and surface intervals, which are essential for safe multi-dive planning. This capability is crucial for divers who may engage in multiple dives in succession, ensuring they remain within safe limits to avoid decompression sickness. The other statements reflect accurate features of dive computers. Most models indeed require a battery replacement annually due to the power needed for the computer's functions. Advanced models are designed to accommodate multiple gas mixes, which is particularly useful for technical divers who may change gases during a dive. Additionally, many dive computers have the functionality to log dives, allowing divers to keep track of their dive profiles, conditions, and other relevant data for future reference.
