Review on 2021 Latest GPS Wireless Dog Fence System - Waterproof & Rechargeable Training Collar for Dogs & Cats Over 5 lb - Ideal for Outside Camping Yard - Electric Pet Fence Containment System by Kayla Watson

This fence works like a dome. There are small stakes driven into the ground in the center and around the perimeter where the dog is to stay within the boundaries. The posts are quite small, barely noticeable, but pick up GPS signals. collar, it has all the settings. Also included are 2 adjustable collars that can be shortened. In the collar block there are settings for hit strength and 5 modes, what distance the dog must be from the boundary to receive a hit and the type of fence calibration. The collar signals the dog before the shock is delivered. For the calibration the collar has to be in the setup mode and in the middle of the fence line, after that I can set and fix the reference distance. This calibration must be performed each time the collar is turned off and on again. The collar is rechargeable.
