What is the standard practice regarding the use of dive computers?

Using dive computers is critical for ensuring diver safety and monitoring key parameters throughout a dive. Regular checks on a dive computer during the dive allow divers to stay informed about their current depth, remaining bottom time, and nitrogen absorption levels. This real-time data helps divers make informed decisions while underwater, such as adjusting their depth or ascent rate to avoid decompression sickness.

In addition, dive computers can provide alerts for ascending too quickly or for reaching predetermined limits. This practice of regularly checking the device helps prevent accidents related to exceeding limits that might not be immediately obvious, reinforcing their crucial role in modern diving practices. The other choices either downplay the importance of dive computers or misrepresent their role in safe diving practices.
