The HTO stretch cord allows you to keep the items close to you until you need them, when you need them. When deployed, the cord stretches to where you require the attached items to reach, but still secure to its tether so if you drop it, you won’t lose it.
 
It comes with a large split ring which will attach to most tools. It can also be used for attaching a net to a D ring too
