What factor can affect your ability to follow the line correctly during a dive?

Visibility conditions significantly impact your ability to follow the line correctly during a dive. In low visibility situations, divers may have difficulty locating the line or maintaining orientation, making it challenging to stay accurately on course. Clear visibility allows divers to see the line directly, assess their surroundings, and navigate effectively, ensuring they can follow their planned route without deviation.

The other factors, while important for overall diving safety and performance, do not directly influence the immediate ability to follow a line under water. For instance, water pressure can affect divers physically and their equipment but does not primarily interfere with the ability to see or follow the line. Similarly, the type of equipment may contribute to comfort or safety but does not inherently change visibility. Lastly, experience can enhance a diver's understanding and technique, but in conditions of limited visibility, even seasoned divers must rely on visibility to follow a guide line correctly.
