Last month was demobing a drill back to a camp. had 2500ft of waterline to p/u so we slung it in 600ft lengths on end of a 100ft line to a tight spot in the camp and coiled it up on the way down. 700AGL before load left the ground....does that count Try it using Vert ref window in an Astar, looks a long way down
fun times but doable no problem
. Also use 200ft line on a regular basis.
