In the USA, most people will call this product under hood animal repellent, but in most European countries, people will name it marten repellent. But actually, it is the same product.
Following you can check the real testing video.
As you can see from the video, the pointer in the ultrasonic test device (the right one) is vibrating when the repeller is working, which means that the repeller is emiting the ultrasonic sound, and the frequency is variable.
The marten repeller will work continuely until the car moving. And it works at a variable frequency (22-45khz) at different time, in order to have a better result to repel.
Following is the working mode,
20s →40s →40s→40s→40s→60s→60s→120s ( Cycle working, S=Seconds)
Note: The Under Hood Animal Repeller is operated by vehicle battery, the fire-resistant device that can be easily mounted within any car, tractor, snowmobile, boat or other vehicles.
Some clients are worry about the vehicle battery will be consumed too fast. To solve this issue, we can reduce the working current to 15-20mAh (It has the same effect)
