KNOWLEDGE IS POWER

Avoiding Line Dump: Your Essential Guide

Maybe this is debatable but we’re pretty sure that getting line-dumped might be the worst way to get dumped. One thing is for sure, though: nobody wants the pain of an out-of-sequence deployment in their lives.

We recently received some footage from an Apex jumper who experienced a pretty gnarly out-of-sequence deployment on a big wall jump. Check it out: The jumper lost riser tension, but luckily avoided reaching line stretch with a tension knot. (Phew.)

The forces exerted by the re-tensioning of the system, however, whipped the risers with enough force to peel both toggles from the riser Velcro, and came out in some clenchy line twists. This stuff happens—it’s part of our sport—but there are things you can do to coax the fates to your side. Here’s our best advice:

  • If you are using a Traditional Tail Pocket, which is the most common option with all of the major manufacturers, make sure that the Velcro on your tail pocket and toggles is crispy-fresh. Replace it as soon as it starts to show age.
  • If you are using a Top Loading Tail Pocket the risk of line dump is reduced, but it is still important to pay attention to your Velcro!
  • Check the condition of the Velcro on your risers, while you’re at it.
  • “Set” the Velcro after matching it together. To do this, just apply a small twisting, pinching action. This helps the hook marry the loop, for a happily-ever-after ending.
