The Sportdog’s SDF-100 is the perfect solution for dogs of any temperament. It doesn’t matter if your dog is hard to train since the SDF-100 has shown results with the most stubborn of dogs.

Principle of Operation

The system works by emitting radio waves from the transmitter to the far end of the boundaries that you decide to set for your dog. The dog is then trained to learn where the boundaries are through the use of training flags that will give the animal a visual guide. If the dog apporaches the invisible fence, then its collar will emit a warning sound indicating that the animal is too close to it. When the pet tries to cross the boundary limit, progressive static electric pulses are offered which in turn educate him to be contained within the preset area in the long run.

Fitted with an in-built lightening protection mechanism, the waterproof collar operates using a 9V battery that needs to be replaced once in every 6-12 months. The informative DVD that comes with every SDF-100 is very helpful in getting the pets trained easily.

Additional Features

For extra safety, the Sportdog’s in ground fence has a feature called anti-linger, which prevents your dog from escaping its assigned area even after the batteries are out of power. Also, the correction received by your dog can be adjusted to match its temperament, which comes handy when dealing with very stubborn dogs. Other noteworthy features are the low battery indicator, the loop indicant, and a collar that can be adjusted to your dog’s neck’s size.

The collar receiver of SDF-100 is designed to suit dogs that are over 4,5 kilograms. It’s not advised to use it on smaller dogs. The set allows you to build safe areas of 1000 feet of perimeter, and even more if you decide to buy additional wire. Additional collars when used with SDF-100 can aid the pet owner further in containing multiple pets within predefined boundaries.
