Additional waterproof collar for electric fence for dogs W-227B The receiver (collar) in the set is waterproof, so there is no risk of damage in the rain. The electronic fencing system, made of a transmitter, an antenna cable and a collar, will help you determine a safe run for your pet. You will create "no-go zones" without taking away your dog's freedom and fun. Possibility to arrange tunnels - In order for the dog to pass through the place where the cable has been buried, it must be braided. Setting the distance of zones - Using the control device, we can increase or decrease the distance of zones from the cable. Collar with standby system - A longer lack of movement on the part of the dog puts the collar to sleep. This solution allows you to extend the battery life . Movement of the dog activates the collar again. After starting, the system starts working immediately and starts "standby". The area is divided into 2 zones. 1 warning and 2 corrective (electrical impulse). When the dog crosses the border of the first zone (warning zone), the dog will sound a beep and the collar will start to squeal. After crossing the second zone, the collar will additionally activate a correction (electrical) impulse. For the impulse to stop, the dog will have to leave the forbidden zone. After leaving the forbidden zone, the system returns to the standby mode and waits for the dog to continue to behave. The distance between the two zones is freely set on the controlling terminal. The system will quickly teach your pet what terrain it can use and what it can't. To increase the effectiveness of the training, the area can be marked with flags (included) . They will help you to spot the forbidden zone faster. The antenna cable (insulated cable closed in a loop) - powered from the transmitter - must not be interrupted anywhere for correct operation. The voltage in the antenna cable does not exceed 12 V, which means that if the cable is broken, it will not harm it.

Collar for dogs weighing 5-50 kg . We remind you that the given value is approximate, because the dog is a living creature and everyone reacts differently to its actions. It is possible that the collar will work properly on a dog weighing more than 50 kg, or it will not function properly at a weight of 45 kg. It is not recommended to use a collar for dogs with a small weight (less than 5 kg), as it can hurt the dog.
