The 6 Best Marten fright

Table of Contents:

The marten fright is generally a small electrical device, which should keep the martens from climbing into the engine compartment of a passenger car. This prevents martens from biting hoses or cables inside the engine compartment. The devices, which are usually as large as the palm of your hand, are very suitable for permanent installation. For the marten fright the term marten fright has established itself today also still. The manufacturers also sell the devices under the name Marder-Schocker or Ultraschall-Scheuche, depending on how they work.

Martens usually use the car battery for the power supply or the device has its own battery. Depending on the control method or type of defence, the device sends an ultrasonic signal or the marten is driven into the engine compartment by a current surge during climbing. With the current surge the method works according to the principle of an electric fence at the cow pasture. The current-carrying contact plates do not require any drilling for fastening. Metal components in the engine compartment and the body provide the necessary minus pole. An acoustic signal is another method, which is not perceived by humans, but drives away a marten. Most marten insects switch off automatically while driving. The models also have safety switches when working with electric shocks. Even when the bonnet is opened, it switches the unit off automatically. For example, there is no danger if the oil level is checked or if the windscreen waxing water is refilled.

A marten scare prevents a marten from getting into the engine compartment of a passenger car. He can’t bite hoses or cables with it. Unwanted workshop visits and expensive invoices can thus be prevented. Compared to the alternative methods, the electrical devices can keep a marten permanently away from the vehicle. Many marten crickets are suitable for different makes of car. If a new car is purchased, the device is removed and continues to be used. It is to be noted that it does not usually remain with the unique marten damage, because the animals come again. Without the marten fright it comes then again and again to repairs and calculations. For the installation at the garage or at the carport there are ultrasonic devices with loudspeakers and with sound pressure level. So after preventing unpleasant damage, it is absolutely a worthwhile investment.

If you are interested in martens, you should know that there are different species. The individual models mainly differ in their mode of action. Two defence methods have prevailed and these are ultrasound and electroshock. With the ultrasonic devices an acoustic signal is emitted, with which the marten is driven into the escape. The frequency of the signal is 20 kHz and the sound pressure level is about 100 dB. At the ADAC a test showed that the martens get used to the devices when the volume is lower. Some models also constantly change the frequency and this prevents the habituation effect. Ultrasonic devices are often connected to the car battery or have their own battery. The advantage of the ultrasonic defence method is that some of these can also be installed in carports and that assembly is simple. A disadvantage can be that habituation effects may occur under certain circumstances. With the electric shock defense method, a marten scare can charge up to eight contact plates. These plates are preferentially attached to the popular access points of the martens. If the marten climbs into the engine compartment, the contact plates are touched and there is an electric shock. The electric shock does not harm the marten, it drives it away however. The lasting effectiveness of the marten repellent method has been confirmed by studies carried out by the University of Giessen and by the practical experience of many drivers. Here there are fewer devices with their own battery and usually the electricity from the car battery is used. The advantage of the electric shock defence method is that it can be extended with additional contact plates and is also very reliable. As a disadvantage it must be said that the assembly is somewhat complex. Some manufacturers also offer the combination of both devices, where both defense methods are discovered in only one system. If you want to be sure, you can use the combination device.

First of all, everyone has to decide on a defence method and here there is electroshock or ultrasound. If the device offers the possibility with ultrasound, then the installation is uncomplicated and the costs compared to the electric shock model are clearly lower. This, however, is supported by the higher reliability of the electric shock as a defence method. If you don’t have the courage to install it yourself, you can also have the workshop install the marten fright. It is always important that the workshop costs are included in the calculation. If you own a camping bus or minibus, for example, you should better choose the model that has many contact plates. It is also possible that some models can be extended by contact plates. However, if you choose ultrasound, you should be aware that this model offers frequency modulation. The sound pressure level should be at least 100 dB. The marten defense market is determined by comparatively small brands. Some manufacturers specialise in the segment and some only offer a single model. Well-known manufacturers are Kemo, Mardersicher, Gardigo, Stop & Go and HJH. For many, the quality of workmanship is important when purchasing. Even though all models have a plastic housing, there are still differences in the processing material thickness. Some inferior models have an unstable and light case and the high-priced devices offer stable mounting points and a rather robust case. With the high-priced devices the life span is usually long and usually they can be fastened also simply with the engine compartment. It is also important that the complete accessories for installation are included with a device. Sometimes additional fixing material is needed and often all cable ties and screws are included. It is also important that the instructions are written in an understandable way. The pictures should explain the device installation and often only a text is available here. It is also important to know in which languages the manual was written. The frustration during installation is prevented by the comprehensible instructions and the complete installation accessories and the installation time is thus reduced. It is best if there is an indicator lamp on the device. A control tone is also often emitted periodically to signal that the system is ready for operation. Cheap devices unfortunately often do without the indispensable equipment feature. The hood switch is also often important, because it contributes to your own safety. When the bonnet is opened, the unit switches itself off. Unfortunately, not all martens are equipped with this switch. However, some manufacturers offer this switch as an accessory.
