What defines a horizontal highline system?

A horizontal highline system is characterized by two suspension points that are close to being on the same level. This configuration allows for a stable line that can be traversed by personnel or equipment in a more controlled manner, reducing the risk of significant downward movement or swing that could occur if the points were at significantly different elevations.

This system is commonly used in various scenarios, such as technical rescue operations or industrial applications, providing a means for safer movement across distances without the complications that come from having one point much higher than the other. The careful alignment of the suspension points contributes to maintaining the integrity of the system and ensuring that loads are evenly distributed.

The other choices highlight different aspects of highline systems that do not align with the standard definition of a horizontal highline.
