Which of the following is NOT a recommend feature of a Total Diving System?

The recommendation of features for a Total Diving System revolves around enhancing safety, performance, and usability. The component that is not considered essential in the context of functional diving gear is color coordination.

While color coordination may enhance the aesthetic appeal of diving equipment or assist in visibility within certain contexts, it does not significantly contribute to the safety or operational effectiveness of diving gear. In contrast, features like an integrated weight system, air supply redundancy, and properly fitted equipment are critical for diver safety and comfort.

An integrated weight system helps divers manage buoyancy more effectively, air supply redundancy ensures that a diver has a backup source of air in case of an emergency, and properly fitted equipment is vital for mobility and preventing injuries. Therefore, while color coordination might be visually appealing, it does not align with the functional priorities that define a Total Diving System.
