Collection Home
I don't collect cable ladders, but I have acquired a few over the years. In my part of the world, people shouldn’t call themselves cavers, let alone vertical cavers, without being comfortable climbing cable ladders. Now somewhat overshadowed by rope techniques or even shunned by the “we don’t need to learn anything invented before 2012” knowledge denyers, ladders are sometimes the best option for short drops, especially when used by moderate-size groups in hybrid rappel-in, ladder -out systems.
