This comprehensive dog training collar system offers three effective and safe training modes to help teach basic obedience commands and correct unwanted behaviors. The beep, vibration, and static shock modes provide flexible options for training dogs of different temperaments and sizes. The system includes an advanced recording function that allows you to record a four-second voice command and play it through the transmitter, adding a personalized touch to your training sessions. A safety keypad lock on the remote control prevents accidental activation and misuse during handling. The collar receiver features IP65 waterproof protection, making it suitable for outdoor training activities in various weather conditions at the park, beach, or backyard. With an impressive remote range of up to 984 feet, you can maintain control and communication with your dog even at a distance. The system supports three channels, allowing you to train multiple dogs simultaneously with separate receivers. Both the remote transmitter and collar receiver are equipped with rechargeable 300mAh lithium batteries that charge in approximately two hours using the included 2-in-1 charging cable. Nine adjustable intensity levels are available for both static shock and vibration modes, ranging from gentle to firm correction, so you can customize the training experience to match your dog's sensitivity and learning pace. The collar receiver is constructed from durable ABS plastic, comfortable silicone contact points, and an adjustable nylon strap. The remote transmitter automatically enters sleep mode after one minute of inactivity to conserve battery life and can maintain standby time of 10 to 15 days depending on usage frequency.
