The a-wasp has been specially developed to extend ‘the ability of the police to exercise persuasion, advice and warning’ without resorting to force.

A person-carried device operating at great range, the A-wasp operates in two primary modes. Firstly, the attention of individuals or small groups can be assured through the emission of a very narrow beam of an entirely safe but intense sound.

Secondly, very clear verbal messages or instructions can be transmitted which cut through the ambient noise and remain clear over very significant distances.
