Animal welfare equipment uses a variety of cutting-edge technologies to ensure the optimal protection of your vehicle. The main technology for returning rodents and animals is an ultrasonic booster with two preset decibels (acoustic), which gives you optimal protection. This technique automatically changes and allows for an ever-changing frequency, so animals and pests don't have to produce the same sounds. Made from tough, heat-resistant materials that can Withstand medium engine heat without melting. It uses your vehicle's battery to operate, compatible with 12V and 24V batteries that use medium cars and trucks. Easy to install: We understand that not everyone is tech-friendly, that's why we developed the animal/pest controller for your car, which is simple and can be done in minutes. Protection: Multiple built-in protection features so you don't damage yourself, your car or the device. Low voltage protection, positive and negative polarity protection, 12V and 24V compatible (automatically detects battery voltage and takes the required voltage.) & Construction Material (The material is made with high temperature resistance and can withstand high and cold temperatures.) No harmful chemicals: With our technology and our ultrasonic wave with all its smart technology, this is the best animal/pest controller for your vehicle on the market. We focus on pure repelling and not killing, so there is no harm to the animals and rodents it repels, such as cats, rats, mice, squirrels and other small animals. Product description Effective protection of rodents Mice and rats feel disturbed by the ultrasonic waves of the transmitter and leave your neighborhood. To us humans, these frequencies are not audible. Smart On/Off - Can automatically detect the car's working status and automatically stop working after the car starts. It automatically starts working 5 minutes after the car stops. Material - It is made of sturdy ABS material and flame retardant material which is precisely fused to ensure normal work in the engine compartment. < td> Installation is simple and practical. Connect the two connectors of the power cord to the positive and negative poles of the car battery to make them work. If the battery voltage is lower than 9 .2 V, the product will tell you that the voltage is too low to protect the battery. When the voltage is restored, the product enters sleep mode. The marten tusk generates a sound frequency of 12-45 KHz, which can effectively stimulate hearing and the rat's nervous system, the marten feels uncomfortable and unbearable, so far from the sound source without seriously injuring or killing it. < /table> Micro fuse: 0.5AReflected beam an
