With 2.4GHz technology and new dual antenna design, the new version signal stability is drastically improved, which is more stable and accurate. We use feet instead of meters to indicate distance (five different radius:100ft/200ft/300ft/500ft/990ft). It's usable in any outdoor terrain. When your dog is out of range, the receiver will beep, and then a low 3.7V voltage mild electrostatic shock discourages the dog from exiting the range.
One transmitter can control as many dogs as you want, at the same time, the transmitter and collar receivers are automatically paired without manual operation. (EXTRA COLLARS LINK--https://www.amazon.com/dp/B083LWZ6FX). You can choose five different control radius distances: 100/200/300/500/990 feet. The range of the fence is defined as a circle (with selected radius) centered on the transmitter.
The new version improves the battery design, making the product last longer and the battery more stable.The receiver and the transmitter are rechargeable. With normal use, the battery can last for weeks. If the collar does not work, it will automatically enter the standby mode. The standby mode can be maintained for more than six months, and it can be awakened by the dog's movement or human touch.
The collar is made of eco-friendly TPU material and will dissolve into powder finally. The outer layer is equipped with a reflective belt to keep your dogs safe at night. The receiver is IP65 dust-proof and IPX7 waterproof and can be used safely in the rain and wet environments.The collar size ranges from 8 to 28 inches, suitable for dogs of all sizes (between 10 to 110 pounds), and is adjustable.
The receiver operates at a voltage of 3.7V and emits static electricity without harming the dog's hair.There are two sets of conductive columns of different lengths in black silicone covers. You may choose the right conductive column and decide whether to install the silicone cover or not. The silicone covers minimize the stimulation of electric shock to your dog.Your satisfaction is important to us. Please contact us if you have any problems.
