The main advantage of our waterproof devices is that they allow for more effective defence. The waterproofing also allows the device to be installed low down in the vehicle, in areas that may become very wet. The all-new K&K Multi-contact high-voltage brushes can ‘catch’ the marten even before it enters the engine compartment. Conventional contact plates can only trigger high voltage through the marten’s paws and snout. The fur, on the other hand, insulates and protects the nocturnal predator. The all-new +/- brush strands now run right through the fur to the body of the animal and thus increase the attack surface many times over.
