I have another Jon Line related question.
The one I have is like a long dog leash. I loop it around the anchor line and clip it to itself and then hold on to the loop/handle at the other end. Should I be feeding it through the loop and using the clip on my chest D-ring?
You can secure the line to your harness d-ring (chest) for long stops or simply hold the hand loop in the case of yours for short stops.....remembering that if you let go of that handle in current you will now be drift diving! By clipping off you leave both hands free for managing/securing other gear as you prepare to leave the water at some point.
