Is a wired in-ground fence better than a wireless GPS fence?

For boundary precision and reliability, reviewers consistently favor wired in-ground systems because the buried wire defines an exact line. GPS and wireless systems are easier to install and portable, but reviewers across r/germanshepherds and r/Dogowners flag accuracy drift (often 10–30 feet), notification lag, and signal issues near trees or slopes. Pick wired for precision, GPS for flexibility and large or irregular properties.
