When the mine is deployed with the chemical fuze it is very difficult to detect because the only metal in the mine is the detonator capsule. There is a secondary fuze well on the bottom of the mine that can accept a fuze allowing remote command detonation of the mine.
The top of the mine has a large pressure plate which rests on top of the fuze assembly. Two fuzes are available for the mine, a conventional ball bearing retained striker and a chemical fuze, containing a glass ampule of acid over a flash composition.
