eXtreme Dog Fence 1st Generation Compatible Add-on Collar Receiver
** ONLY COMPATIBLE WITH THE GENERATION 1 TRANSMITTER (WHITE WITH GREY CENTER) **
The eXtreme Dog Fence system can accommodate an unlimited number of dogs, with the purchase of additional fence dog collars. These dog shock collars have 5 levels of correction that you set, per each dog's individual personality and temperament. They come from the factory set on level 1 (the lightest correction setting). You can increase the collar level 1 step at a time, until you see some kind of physical reaction from your dog when he/she gets the correction. You'll want to see their ears perk up, or neck cock back, or perhaps they will scratch at the collar. This is a good correction level to start your dog on.

This package includes the following:

1x Waterproof Collar Receiver (Grey Receiver / Black Strap)
2x Sets of Contact Points (1x Small, 1x Large)
2x Sets of Comfort Contact Covers
2x Sets of Contact Training Caps
1x Battery for Collar Receiver
