Apparently 180 feet (54 meters) of Zing-It is a tad short for you big tree climbers out there! To date Treetools have sold Samson Zing-It in a pre-cut length but some climbers have complained the 'factory' Zing-It container is short by about 10 meters for many of their climbs so we have added custom cut lengths to the catalog.
Standard tree entry set-up for most climbers is Zing-It combined with a 8oz Harrison Rocket conveniently held in a Faltheimer Cube. The 1.75 mm Zing-It is light enough to be carried by the 8 oz bag but strong enough to stand up to a hard pull if you get the system snagged.
It's better to have the correct length of line for the throw: knots in the system will work but they do create drag on the line, reducing velocity and accuracy. Save yourself those extra throws and get Treetools to cut you the right length of Zing-It for the job.
