Use their own sensors against them!

^{[citation needed]}

The sophisticated system emits a warning tone whenever a radar beam is detected. Considering the specificity of the radar transmissions, this function is completely reliable. This unit can also be used to locate the source of the radar by triangulation; when the direction of the beam is ascertained, the tone changes to a rapid chirping (this function has a 60% chance of success). The unit has a 100m range and its the size of a pack of cigarettes.
