This dog training collar receiver is engineered with high-grade ABS materials and a premium sealing process for durability and IP67 waterproof protection. It can be used confidently in rainy or snowy conditions, though it should not be submerged in water. The built-in high-sensitivity chip receives remote control signals from up to 3280 feet away, providing reliable long-range communication between the transmitter and receiver. The receiver supports three distinct training modes: shock, vibration, and beep. These modes allow pet owners to correct unwanted behaviors effectively and humanely based on their dog's temperament and training needs. With 100 adjustable levels for both static shock and vibration, you can customize the intensity to suit your dog's size and sensitivity. Powered by a 650mAh lithium battery, the receiver offers approximately 25 to 40 days of standby time depending on usage frequency. A full charge takes about two hours using the included charging cable. The receiver features an intelligent battery indicator that beeps to alert you when charging is needed, ensuring your training sessions are never interrupted unexpectedly.
