Technical divers use a Jon Line to maintain a certain depth when ascent lines are crowded with other divers or when the current is ripping. Our Jon Line easily clips onto an anchor line or down line and is also easy to remove. Stored inside a small, dispenser pouch is our 5-foot yellow 1-inch nylon webbing and with a marine-grade, stainless steel carabineer. The pouch will slide easily onto any standard 2-inch webbing. The carabineer can be clipped into lines to free run up and down the line or wrapped and clipped for a friction wrap around a anchor/down line.
