Dogtra E-Fence 3500 Rechargeable Underground Fence System


The Dogtra E-Fence 3500 is an effective underground containment system for mild to stubborn dogs. Set custom boundaries around your property that allows your dog to be safe in your yard withut unsightly or expensive fencing.

Choose the area you wish to contain. Set up the flags to warn the dog that he is nearing the boundary. The collar emits a vibration signal that warns him prior to correcting him. With the use of the visual flags and the vibration, he soon learns the limits of his territory.

If he transgresses the warning area, the collar will tell him that he doesn't wish to go there by giving him an unpleasant but harmless electrical stimulation.

There won't be any question if the fence is working. It incorporates a wire continuity indicator that shows the fence is operational.

Underground Dog Fence has 8 levels of correction control. You can choose a different level for each dog to suite their individual temperaments. Dogtra's filtering system prevents reception from outside sources other than your transmitter. And the receiver has an automatic control that limits the stimulus to eight seconds.

User-friendly controls make setting up easy. And the waterproof collar has a rechargeable battery to make life easy.

The fence wire must make a continuous loop around your property for your system to operate. The signal is delivered from the terminal of the transmitter, through the fence wire, back to the other terminal on the transmitter. When this is accomplished, the wire continuity light will emit 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.)
