Caver's Tools

Canary Torch

A lightweight knurled metal tube with a domed crystal lens on one end. Glows in the presence of breathable air.

Walking Cam
A spider-legged automaton that can climb any surface. Strong enough to tow an attached person up a sheer wall. Can climb by itself to a specific location and set pitons for others to follow. Collapses into a 7" diameter orb.

Autocaisson
A heavy iron belt of sealed boxes 3" on a side. Explosively deploys in a cave-in or flood to form an interlinked spherical metal shell around the wearer and hold back fallen rubble or water.

Airbag
A light silk vest with padding along the spine and collar. Explosively inflates into a protective cocoon if the wearer falls, is thrown, or suffers an impact.

Glowstick
A four-color paint pen that writes on any surface and never runs out. The ink glows and self-erases by sublimation on command. Shake before using, makes a chiming noise.

Shrieker Box
A handheld rectangular device with a screen and dials on the front and a cone-shaped emitter on the top. Uses sonar to measure the thickness and depth of surrounding material when pointed at a solid surface. Can measure from 1/2" to 2 miles. Dials control the signal's strength and sensitivity. Works best on stone, do not operate on living tissue.
