Overview
A GPS-based wireless containment system for dogs, using satellite positioning instead of a buried wire to define a boundary. The collar unit is rechargeable and rated IPX7 for water resistance.
Two containment modes are offered, a simple circular boundary and a free-form shape that can be traced to fit an irregular yard. It is recommended for large and medium dog breeds under the DJNFGQ brand, model F500, and is built for all life stages.
- GPS satellite containment, no buried wire
- IPX7 waterproof rechargeable collar
- Circular and free-form fence modes
- Built for medium and large breeds
Who it's for
Owners of medium or large dogs who want a yard boundary without digging in a physical wire, especially where the yard shape is not a simple circle.
