The available lengths range from approximately 2.44 to 3.05 m. A shorter version is easier to handle on a crowded bank; a longer one provides more height for guiding the line. Line-class ratings vary by model: check the casting range that matches your complete setup.
Unroll the sections along the axis and align the guides before applying tension to the line. When storing, remove sand and moisture from the sliding sections. The compact design makes it easy to transport, but you should still protect the guides.
