was the first device of this type, composed of two elements: the Wet-beacon is the fixed unit that acts as a beacon, the Wet-finder is the mobile unit that searches and indicates the direction to return to the fixed unit
NOTE
the device could not stand the presence of obstacles, so the mobile unit found it difficult to identify the fixed unit if a rock or other intervened between the two
