Another innovative geocaching clue brought to you by Cache At Night. This device was invented by German geocacher that wanted to offer something a little different. If you know anything about geocaching in Germany you will know they take it seriously. Similar to Laser Loci this device is activated when a bright light is shined on the sensor. When activated the device will display numbers on a seven segment display. The device is programmed via a magnet which allows you to seal the device in a container yet program it in the field.
A container is not provided.
