Patent attributes
A lighted orientation device according to the present invention includes an outer housing having a construction that is resilient, generally spherical, and defines an interior space for holding fluid. A directional indicator such as a float is positioned within the outer housing and rises to a top surface of the fluid for indicating an upward direction. The float is also constructed of a resilient material and includes first and second chemicals separated by a breakable membrane. The two chemicals react when combined to produce light, whereby a user may view the float and ascertain which direction is “up”. The lighted orientation device may be coupled to a digging tool according to an alternative embodiment such that a user may begin digging out of an avalanche as soon as their orientation is determined.
