“Dead” Drop Spike
Communication between an agent and his/her handler always poses a risk. A “dead” drop allows secure communication by one person leaving and later the other person picking up material at a prearranged location. This eliminates the need for direct contact. This device is a spike that one could push into the ground. It is hollow in the middle and could contain messages, documents, or film.
