PetSafe Stay & Play Wireless Fence

This simple to use, portable pet boundary system simply plugs into a standard power outlet and can cover a circular area of up to 64 meters diameter.

The transmitter communicates with the transmitter collar you place on your dog and delivers a warning tone should your dog approach the boundary. If the dog continues toward the containment edge the collar will let off a harmless but surprising electrical stimulation.

The collar's battery is rechargeable and lasts about 3 weeks.

Transmitter with power adaptor
Receiver collar for neck size 15cm - 58cm
Receiver charger 
50 training flags
