It is light, fast at mid-rope maneuvers, and easy to wear while caving. It is not as efficient as ropewalking systems. https://static1.squarespace.com/static/5d2f9f3650b8c90001ec831c/t/5d4a23ddb25a660001591278/1568474144506/Ropewalker.jpg Vertical Caving - Ropewalker The double-bungee ropewalker ascending system is complicated and heavy, but is the most efficient and fastest way to climb a free-hanging single rope. https://static1.squarespace.com/static/5d2f9f3650b8c90001ec831c/t/5d4a2cf6d2193d0001703f6d/1568474144517/Screen%2BShot%2B2019-08-06%2Bat%2B9.42.42%2BPM.jpg Vertical Caving - Deviations Deviations are used in alpine rigging to direct the rope away from hazards such as edges, loose rock, and running water. Crossing them is usually straightforward, but there are a few tricks and techniques that will help. https://static1.squarespace.com/static/5d2f9f3650b8c90001ec831c/t/5d496627d1f9b100017f6edc/1568474144514/Screen%2BShot%2B2019-08-06%2Bat%2B7.21.53%2BAM.jpg Vertical Caving - rebelays Rebelays help keep the rope from contacting the cave walls so that abrasion is prevented. Crossing them is a fundamental vertical technique required when dealing with alpine rigging. https://static1.squarespace.com/static/5d2f9f3650b8c90001ec831c/t/5d4a2d93d2193d00017046a1/1568474144520/Screen%2BShot%2B2019-08-06%2Bat%2B9.39.44%2BPM.jpg Vertical Caving - crossing knots Knots should be avoided when rigging caves, but occasionally a worn spot must be isolated or a rope is too short and the rope and rigging on-hand may require a knot be used temporarily. The skills to cross mid-rope knots is something that should be in every cavers repertoire. https://static1.squarespace.com/static/5d2f9f3650b8c90001ec831c/t/5d4a2723b1dac90001c3855b/1568474144509/Screen%2BShot%2B2019-08-06%2Bat%2B9.16.17%2BPM.jpg Vertical Caving - Mitchell system The Mitchell system is a ropewalker system that is quicker to get on or off the rope, and faster at mid-rope maneuvers than a traditional Ropewalker system. It is also very fast and efficient at down-climbing. https://static1.squarespace.com/static/5d2f9f3650b8c90001ec831c/t/5d48a99ebf13a80001b6b93d/1568474144500/Descenders2.jpg Vertical Caving - Descending Descenders used in cave exploration include bobbins, micro-racks, and j-frame racks https://static1.squarespace.com/static/5d2f9f3650b8c90001ec831c/t/5d4868bef985d700015ed849/1568474144497/Lech_Max-30.jpg Vertical Caving https://www.derekbristol.com/gear-overview daily 0.75 2020-09-18 https://static1.squarespace.com/static/5d2f9f3650b8c90001ec831c/t/5d80f98f70535913fd931c77/1574199832208/Knife.jpg Caving Gear - knives Critical for rigging to cut ropes to length or remove old webbing or cord.

They protect your head from low ceilings, from falling rocks, and from impacts during a fall. They also provide a place to mount a headlamp. For most cavers an ABS hardshell or hardshell / foam hybrid helmet will be the best choice. https://static1.squarespace.com/static/5d2f9f3650b8c90001ec831c/t/5d7d6b97f26e3245443649e2/1568656975413/Stove.jpg Caving Gear - Stoves While not a necessary piece of gear for most day-trips, an invaluable item on multi-day expeditions, and useful in cold alpine caves. https://static1.squarespace.com/static/5d2f9f3650b8c90001ec831c/t/5d7d67c81fb8f92f1aec3864/1568656935687/Ascenders.jpg Caving Gear - Ascenders Ascenders, or rope grabs, come in a variety of forms. Some have handles, others do not. Some open to the side, while others surround the rope. They are designed to be easily moved up the rope, but to grab and hold tight when pulled back down. They are critical for climbing rope or holding the rope as part of a haul system. https://static1.squarespace.com/static/5d2f9f3650b8c90001ec831c/t/5d7d6a760f51e83141ec99ad/1568656955864/Descender.jpg Caving Gear - Descenders Descenders, or rappel devices, apply friction to the rope to control rate of descent. The most common devices used for caving are the bobbin and brake bar rack. https://static1.squarespace.com/static/5d2f9f3650b8c90001ec831c/t/5d7d69bdf8ba7b48aa81e37b/1568565126024/Headlamp.jpg Caving Gear - headlamps A helmet-mounted, hands-free headlamp is one of the very fundamental pieces of caving gear. There are a myriad of options from under $20 to over $1000. https://static1.squarespace.com/static/5d2f9f3650b8c90001ec831c/t/5d7d6b30f3d9357e8d370d80/1568656915388/Harness.jpg Caving Gear - harnesses A harness is the central piece of vertical caving gear. All ascending and descending equipment is attached to the caver through the harness. Cavers often use simple harnesses that lack padding and are designed to be abrasion resistant. https://static1.squarespace.com/static/5d2f9f3650b8c90001ec831c/t/5d7ffe4599cb670772b71844/1574199832206/Pack.jpg Caving Gear - cave packs For most types of cave trips there is a need to have a way to carry extra gear that won’t fit in your pockets. A rugged pack that will survive water, mud and abuse is critical to caving. https://static1.squarespace.com/static/5d2f9f3650b8c90001ec831c/t/5d4de28f12c0130001acab41/1565102932529/Gear2.jpg Caving
