Heaflex Dog Training Collar with Remote, 3300ft Remote Dog Shock Collar, IPX7 Waterproof Rechargeable E-Collar, 4 Training Modes (Night LED Light，Beep, Vibration, Shock) for Small Medium Large Dogs

4 Humane Training & Safety Modes: Features 4 effective modes: Beep, Vibration (0-99 levels), Safe Shock (0-99 levels), and a built-in LED Light. The LED mode is specifically designed to help you locate your dog instantly in the dark, ensuring safety during evening walks or night camping.

Smart Sleep & Safety Wake-up Logic: To maximize battery life and prevent accidental corrections, the remote enters auto-sleep when idle. A "Two-Step" safety trigger is required: press any button to wake up the screen first, then press a functional button to send a command. This intelligent design ensures you never trigger the collar by mistake in your pocket.

Instant Response & Power Efficiency: Despite the power-saving sleep mode, the system features Zero-Lag technology. Once woken up, the remote communicates instantly with the receiver. The high-capacity rechargeable battery provides weeks of standby time, making it the perfect companion for long outdoor training sessions.

IPX7 Waterproof for Aquatic Adventures: The receiver is fully sealed with an IP67 waterproof rating, allowing your dog to swim, play in the rain, or splash in puddles without worry. It’s a truly "all-weather" tool for active dogs (Note: Remote is splash-proof only).

Extended Control Range for All Breeds: With a stable signal reaching up to 3300ft, you can maintain control in parks or open fields. The adjustable collar strap (8-26 inches) comfortably fits small, medium, and large dogs from 15 to 100 lbs.
