Should I use a coiled SUP board leash?

A coiled leash is today's standard. The leash expands to its full length only when the person falls into the water. Before that, it is tightened and does not drag in the water. This reduces the risk of accidents, as the leash does not easily snag on branches in the water, for example. In addition, a coiled leash does not brake because it does not drag in the water.
