The TPL-310B Trapped Person Locator was designed by Elpam Electronics to detect persons trapped under rubble. This could be as the result of an Earthquake, collapsed building or, military damage. It works via trigonometry which is achieved through the relative positions of the 3 Sensors, which are lowered into the suspected cavities. One of the Sensor units could be utilised as a 2 way communicator with the person who is trapped.

The units have been used extensively both around the world and here in the UK by the London Fire Brigade. This is our last unit left, which also featured in an episode of the TV show London’s Burning. It is in no-working condition and comes with just 1 Sensor (pictured).
