【Harmless to Humans, Animals, and the Environment】 With an expanded detection sensor range compared to conventional cat deterrents, and improvements to the LED strong flash, the animal repelling effect has also been enhanced. Furthermore, it is harmless to humans and the environment, so you can use it without worry. 【Adjustable Detection Range & Automatic Repulsion】 The repeller can detect animals within a 110° field of view in front of it, up to a maximum distance of 10m. The detection distance can be adjusted from 2-10m. When an animal enters the detection range, the repeller automatically emits ultrasonic waves and strong flashes to drive the animal away. (Note: The detection distance may vary slightly depending on the size of the animal, the weather, and the temperature.) 【Solar/USB Charging & Waterproof Design】 1. Solar panel charging: By placing it in a sunny location, you can continuously charge the built-in battery. 2. USB charging: Even on consecutive cloudy or rainy days, you can charge it by connecting it to a USB cable. 3. Waterproof: It can be used without problems even if it gets a little wet from rain. (Note: In the event of heavy rain or a typhoon, please move it indoors temporarily.) 【Five Modes to Repel Various Animals】 ● Mode 1: 13.5KHz〜19.5KHz. Suitable for small animals such as mice. ● Mode 2: 19.5KHz〜28.5KHz. Suitable for large dogs, foxes, etc. ● Mode 3: Audible alarm. Suitable for small dogs, cats, birds, etc. ● Mode 4: LED flash blinking to intimidate animals, suitable for nocturnal animals such as raccoons, wild boars, and weasels. ● Mode 5: Repels all animals and birds. Emits all frequencies of modes 1-3 and activates all functions such as strong flashes. (By varying the ultrasonic waves, it prevents animals from getting used to them.) 【Target Animals & Applicable Locations】 Because it is an ultrasonic sensor for repelling cats, you may hear a slight sound, but it is harmless to humans and animals. To maximize the performance of this product, it is recommended to place it outdoors. It protects fields, lawns, flower beds, balconies, parking lots, etc., from troublesome animals. When animals approach the coverage area of the device, the strong flash and ultrasonic waves increase the success rate of repelling dogs, crows, mice, birds, and cats. It creates an environment that prevents them from getting close to your property. 【Plug-in & Wall-Mountable】 There are two installation methods, so you can easily install the repeller in various places, whether you insert it into the ground or hang it on a wall or tree. ※ To prolong battery life, please fully charge it via USB before use.
