great idear
i have been using a version of this for about 8 years at whitakers nc
this type of recovery can also be used to recover rockets from mud flats, swamps. and ponds.
DO NOT USE THIS METHOD TO RECOVER A ROCKET FROM A POWER LINE !!!!!!!!!!!!!!!!
but instead of using a fishing reel i just put the line in an open box or a plastic bucket.
then i use the fishing line to pull the parachute cord back up over the parachute bridle.
its a good idear to purchase an extra pouch and rubber to replace one if it breaks in the field. store the slingshot out of direct sunlight when not in use it causes the rubber to get weak and break
higher the tree use lighter weight fishing line.
u can purchase a large roll of floresent orange parachute cord from ebay for around 45 bucks. not bad for 1200 feet !!!!
