The Reel and Stand are designed to allow the coupling together of long lengths of rod.
This is most useful when you have to work on long lines most of the time. It allows you to avoid the continual tightening and loosening of the rods for each job. The reel is large enough to allow for more than 150m of rods to be coupled together at a time.
It also has a large diameter so that the rods will straighten when taken off the wheel.
