Description:
"Is it safe to have 2 people on a guided rappel? How much force does it create? Brent Roth (@whitewaterpirate) and Joe Cruikshank demonstrate a guided rappel and I read off the force from the LineScale 2. We now have the LineScale 3 and it records the data internally and is water proof. Check that out at https://www.hownot2.store/linescale
At the top anchor, the peak force was 4.8kn when they were both on it and when repeated, the bottom anchor saw a peak force of 5.07kn. For reference, an 8mm static rope we just tested broke at 14kn in a figure 8." - @HowNOT2
