Simultaneous Control for 2 Dogs: Equipped with a dual-channel remote and two receiver collars (Yellow and Black/Orange), allowing you to train two dogs simultaneously with a single remote. Easily switch between Channel 1 and Channel 2 to send individual commands without confusion. Built-in LED Light for Night Safety: The remote features a built-in LED flashlight, and the receivers include a light mode. This is essential for locating your dogs in low-light conditions or during evening walks, adding an extra layer of safety for you and your pets. 3300Ft Professional Control Range: Offers an impressive range of up to 3300 feet (barrier-free), making it ideal for hunting dogs, working dogs, or extensive outdoor activities where your pets may venture further away. Customizable Intensity for Each Dog: Dogs have different temperaments. The collar allows you to independently adjust vibration (0-99) and static levels (0-99) for each dog, ensuring the training is tailored to their specific size and sensitivity. IPX7 Waterproof & Quick Charging: Both collars are IPX7 waterproof for reliable performance in wet conditions. The system features a 2-in-1 charging cable to charge both the remote and collars efficiently, saving you time. Train Like a Pro with the Heaflex Smart Dog Training System The Heaflex Dog Training Collar is more than just a training tool; it’s a communication bridge between you and your furry friend. Engineered with the latest Smart-Sleep technology and a Night-Locate LED, this professional-grade collar ensures effective training while prioritizing your dog's safety and comfort. Why the Heaflex System Stands Out: The Power of 4 Modes: Most collars only offer three. We’ve added a high-visibility LED Light mode to help you locate your dog instantly after sunset. Combined with Beep, Vibration, and Safe Shock (0-99 levels), you have a complete toolkit for every dog's temperament. Safety-First "Wake-then-Command" Logic: We’ve eliminated accidental shocks without the need for a bulky physical switch. The remote enters a smart sleep mode when idle to save power. A simple press of any button wakes it up, and your next press delivers the command instantly—preventing misoperation while the remote is in your pocket or bag. Built for the Professional & Outdoor Use: With an ultra-long range of up to 3300ft, this system is perfect for open-field training. The IPX7 waterproof receiver is built to endure rainy day hikes or trips to the beach. Customized Sensitivity: With 1-99 adjustable levels, you can find the precise "tickle" that works for your dog’s specific sensitivity, ensuring a humane and effective training experience for medium and large breeds. Package Includes: 1x Remote Transmitter, 2x Receiver Collar, 1x USB Charging Cable, 1x Test Light, and Easy-to-Follow Manual.
