Add an extra 1/2 acre to your dog’s Stay+Play Wireless Fence® or Wireless Pet Containment System™. For larger or uniquely shaped yards, this extra unit can expand your yard coverage. Large, overlapping circular fields create even more outdoor pet paradise and give your pet more room to exercise, play, and stay safe. Plus it’s portable for vacations or other locations.

This extra transmitter isn't a complete system and requires the use of a Wireless Fence Receiver Collar (sold separately). Add a wireless fence collar sized for each pet (not compatible with Wireless Mapping Fence collars).

Great system, 1/11/14
We have used this system for close to 10 years. Having a German short haired pointer and a lab, the system has been awesome. Once our dogs were trained on the system, we have not had any issues.

Works Great, Best Product For The Money, 11/22/13
We had adopted a dog that was fully grown by the time she came to be a part of our family. We had tried everything to keep her in our yard. She broke all the chain tie-outs, and had bit through the thickest cables. Nothing we tried to do seemed to work until we had purchased the wireless transmitter/collar. This unit works great , and we didn't have to pay anybody to install it. It has been three, almost four years, since we had initially purchased the wireless fence. We occasionally have to put the collar on to remind her not to chase after the neighborhood kids on their bikes. I would recommend this to anybody that has a dog that needs a friendly reminder to stay in the yard. Just need to remember to keep an extra battery on hand incase it is time to replace it.

Replacement Charger, 11/9/13
We have been happy with our product. It has kept our dog safe for the past 5 years. However, I recently unplugged the charging cable to the device and inadvertently plugged it into another device. When I tried plugging the charging cable back into our box, it no longer will power our PetSafe Wireless Pet Containment Box. Will the replacement charger solve this problem? Any advice or assistance would be appreciated.
