Is it safe to have 2 people on a guided rappel? How much force does it create? Brent Roth (https://www.facebook.com/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://linegrip.com/LS3
