    Ive got a rack with a titanium top bar made by a machinist friend who was also a caver.

    Great as always. I purchased a CMI rack (initially weary of bulk) due to versatility. It's been a good bit of kit so far.

    Nothing beats a rack for caving and big or small drops. LOL I still have my old BW Coiled ended rack!

    Another easy failsafe trick to guard against rollout is to clip your short cowstail into the eye of the rock as a backup (in addition to having it attached to your d-ring). Rollout is one of the only safety hazards I've actually personally witnessed happen.

    I am a newbie so this may be a dumb question. How does your suggestion prevent rollout? Thank you.

    What is the opposite of rappelling called? How do you get out of steep slopes like this, but not as a straight ascent like with a free hanging rope? And can you just use one ascender on your chest while getting out, and just have the rack behind it so you can just pull it through? Or is that a bad idea?

    Checkout canyoneering and lead climbing. It's an entirely different world of gear and skills needed.

    Hello Mr. Bristol. I have a question, is it ok to do caving with something like a Mad Rock Safeguard / Lifeguard or a Black Diamond ATC? I would like to know Yes/No and why. I am curious about it.

    It's not really a yes/no answer. I can tell you that experienced cavers, in most cases, do not use these devices. The reasons include that they aren't as good at heat dissipation on longer rope pitches. They don't have as much range of friction control as standard caving descenders. They are more difficult to lock-off for hands-free use. The rope can't be attached and detached without fully removing them from a main harness attachment, which increases the risk of dropping the device. They generally don't work well in especially muddy conditions. There are probably other reasons I'm forgetting, but you get the picture. They weren't designed for the rigors and conditions found in caves and therefore don't perform as well. Could they be used in dry caves with a few short simple rappels... sure, but anyone using one would also need to know how to lock it off and do maneuvers like change-overs.

    Use strong screw link with a rack, a thick biner with a bobbin.
