Set of Deramax-Profi-Trio scarecrows

What the Deramax-Profi-Trio set contains: 3 pcs Deramax-Profi high-quality marten and rodent repellers, 3 pcs extension cables (each 10 meters long), 1 pc power splitter.

The Deramax-Profi-Trio repeller set is currently a very popular product against martens and rodents because it meets the requirements of many customers for comprehensive protection of the entire family house, i.e. basement + ground floor + attic. And if the whole set is used only for one floor, there is a significant increase in the effect compared to the use of one scarecrow.

The set is significantly cheaper than buying individual scarers, and the possibility of powering from one central power source is also advantageous. The set is also very good in terms of design, and if you don't use it yourself, try to consider it as a practical and nice gift for your loved ones.

So if you need to protect a larger space, a more fragmented space, a space with stored food or fodder, or you simply want the best option for protection against martens and rodents, we recommend using the Deramax-Profi-Trio set, because more repellers in one space significantly increase their overall effectiveness .

The Deramax-Profi-Trio kit consists of 3 Deramax-Profi spreaders that connect to a central power hub using 10 meter long extension cables. The hub combines all the extension cables and connects them to the central power source (the source is not included in the delivery).

The Deramax-Profi repeller serves to protect indoor and outdoor areas from martens, rodents and shrews. The device is completely safe and noiseless for humans. The pests are permanently disturbed by the ultrasonic signals of the scarecrow and leave the protected area in a short time. The operation of the device is ecological without the use of chemicals.

Automatic change of frequency and power:
The Deramax-Profi exterminator has an automatic change of the ultrasonic frequencies used, which are optimized for the given type of pests. At the same time, there are also controlled changes in the performance of the scarecrow. Coordinated changes in frequency and power contribute significantly to increasing the effectiveness of the repeller and to limiting the possibility of pest habituation to the repeller signal.

Resonance amplification of the ultrasound signal:
The Deramax-Profi extinguisher uses resonant signal amplification, which is important for achieving the highest possible performance with the lowest possible energy consumption. We calibrate the frequencies generated by the electronic circuits of the scarecrow with the resonance frequencies of the used piezo transducers (ultrasound "emitters") within each production series.

Powering the Deramax-Profi-Trio scarifier set:
The Deramax-Profi-Trio set is powered by one central mains power supply (plug adapter). The power supply is not included in the delivery of the scarecrow.

Target group of pests:
Martens, mice, rats, rats, shrews, weasels.

Scarecrow Resistance:
Indoor and outdoor use. The extinguisher is resistant to water, snow, humidity, dust, high temperature and frost (- 25°C to + 80°C).

Safety of the Deramax-Profi scarifier:
From the point of view of the effect on people, the Deramax-Profi scarecrow does not disturb its surroundings with unpleasant noise, it is completely silent and safe. It meets the legal limits set for the maximum level of ultrasound. Our internal rules then go beyond applicable laws and take into account current medical scientific works and WHO recommendations for airborne ultrasound signals. At the same time, this scarecrow for martens and rodents has no negative effect on common domestic or farm animals, such as dogs, cats, horses, poultry, exotic birds, etc.

Comfort of operation:
The device does not need to be set up in any way, it works completely automatically.

Scarecrow Location:
A common solution for placing a scarecrow, and usually also the most practical solution, especially in the case of indoor use, is to place it on the ground in one of the corners of the protected area with the front facing towards the center of the protected area. However, it is also possible to fix the scarecrow using screws or double-sided adhesive tape to a fence, wall, post, window, door, etc., which is most suitable for use in outdoor areas. Even in this case, we recommend directing the front part of the spreader to the center of the protected area.

The range of effectiveness of the Deramax-Profi scarecrow (valid for one scarecrow from the set):
The highest effective distance in front of the scarecrow is up to 28 meters. The range of effective area is up to 650 m². The effective angle of engagement is 180 degrees. The scarer therefore not only has high performance, but the special design of the device ensures the achievement of a very wide effective angle of engagement of 180 degrees, while even at the limit of the declared angle of engagement (that is, outside the main direction of signal emission), the scarer still generates at least 80% of the declared sound pressure level. Of course, the ultrasonic signal also spreads beyond the specified angle of engagement of 180 degrees, but the efficiency is already lower here, and therefore, for the sake of objectivity, we indicate an effective angle of engagement of "only" 180 degrees.

Number of scarecrows in one space:
Any number of ultrasonic scarers can be placed in one place and their signals are not negatively affected in any way. On the contrary, it is common to protect from in particular, larger or more fragmented spaces use more repellers, because a greater number of repellers (repellents) installed in one place means a significantly higher penetration of the protected space by the ultrasonic signal and the overall efficiency increases.
