BHCEY Wireless Electric Dog Fence System

BHCEY Wireless Electric Dog Fence System. It combines a wireless dog fence and a remote training collar.
Here's some helpful information:
It uses a radio signal to create a safe zone for dogs, adjustable from 82 to 1640 feet in radius.
When a dog exceeds the set distance, the collar emits a warning tone, followed by vibration and then a shock until the dog returns to the safe area.
It supports controlling multiple dogs with one transmitter.
The system is waterproof, allowing use in rainy conditions.
The collar and transmitter are rechargeable, with the collar typically needing 1-2 hours to charge.
It is suitable for dogs of all sizes, with an adjustable collar from 8 to 28 inches.
The system can be used as a training tool with adjustable shock levels.
It does not require Wi-Fi to operate.
