Which of the following statements about dive slates is true?

Dive slates are specifically designed for underwater communication and serve as an effective means of facilitating silent communication between divers. Since verbal communication becomes impractical underwater due to the environment and the use of diving gear, dive slates provide divers with a way to convey messages, directions, and instructions visually. This is particularly crucial in situations where divers need to communicate without causing disturbances or increasing the risk of miscommunication due to the ambient noise or physical distance.

Using dive slates, divers can draw diagrams, write messages, or even signify signals that enhance their teamwork and situational awareness. The ability to communicate silently and effectively is essential for safety and coordination during dives, especially in scenarios where clear communication is vital to prevent accidents or misunderstandings.

The other options present limitations that do not reflect the full utility and purpose of dive slates. They are not solely for drawing, nor do they limit communication solely to verbal means, as they are designed to enable visual, written communication. Additionally, although experienced divers may have developed non-verbal cues and signals, suggesting that dive slates are unnecessary for them overlooks the advantages and clarity that the slates can provide in various diving situations.
