Key features Keep you dog safe in your yard by setting custom boundaries around your property! For yards up to 40 acres, the advanced filtering system will prevent your dog from running away thanks to vibration pager only or vibration plus stimulation signal. You can choose between 8 levels from low to medium stimulation. The ultra compact collar is fully waterproof and if you have several four-legged friends you have the possibility to buy additional collars separately. Installation The fence wire must create a continuous loop around your property for your system to operate. You can check that the system is correctly operating thanks to the wire continuity light which emits a constant red indicator. The wire should be buried approximately 4-6 inches into the ground, or deep enough to protect it from being damaged by any machinery or dug up by your dog. The wire does not have to be buried in order to work though, so check everything works fine before digging! Find the User Manual for e-fence 3500 Smart Boundaries here.
