K&K - M4700B - Marten repellent device

The INTENSIVE Marten Repellent Device The world novelty: Multi-contact high-voltage brushes! Most martens can be reliably driven away with pulsating ultrasonic tones. However, particularly aggressive or older animals with altered hearing behavior require even stronger deterrence. The M4700B therefore combines a 360-degree ultrasonic dome with the electric fence principle, which has been perfected by the high-voltage brushes. The M4700B uses the proven principle of high-voltage marten deterrence, but the six flexibly positionable multi-contact high-voltage brushes can do more than ordinary devices: Simple high-voltage contact plates only work if they are touched with a paw or snout and the marten also touches a vehicle part made of conductive material. With the M4700B, it is sufficient if it merely brushes past, because the entire skin of the animal is extended to become the active surface. The multi-contact high-voltage brushes also penetrate through the otherwise insulating, dense fur and have both a positive and a negative pole, which makes the device independent of its surroundings, as the circuit closes even without a conductive vehicle part. Here, even the cleverest animal intruder is doomed to fail! The result is an instructive but harmless shock. So that the small predators cannot evade the “safety net” even in large engine compartments, the system can be expanded by four additional multi-contact high-voltage brushes. Since the device and periphery are also absolutely waterproof, the M4700B can always be placed in the most strategically advantageous position in the engine compartment.
