Imagine being a thousand feet underground with a single headlamp beam to guide your way through a seemingly never-ending passage. Your battery is running low and you have just passed the same rock formation for the third time. You become disoriented, afraid, hungry, and fatigued, with no chance of communicating with someone above ground for help and no idea how to get back to the surface. The Digital Junction Tracker (D.J.T.) is a digital beacon and receiver that will give cave explorers a more reliable way to find their way out of the cave. It will also act as a tracking device for rescue teams to find cave explorers who have lost their way, are injured, or become stuck in a cave and need to be retrieved. The D.J.T. is an innovation with the potential to save lives.
