Long lines (once called a 'longe').
10 m long in 6 mm double braid Australian made poly cord with a load rating of 875 kgs and fitted with a Henssgen mid weight solid brass swivel snap hook.
Reviewed as follows: - resists abrasions from vegetation, rocks, stones etc, soft in the hand but suggest you knot the cord where you like, knots are easily undone & the cord has no memory, easily cleaned in warm water especially if used in salt water, a drop of oil on the spring in the snap hook is a good idea & dry out before storage. excellent value for a versatile bit of gear.
Can be used as a recall lead, tracking lead, beach lead etc etc.
