Tri Tronics Expandable Receiver For G2 & G3 Models

This Collar will turn your G2 or Sport G3 into a multiple dog unit. Very easy to program and they are the same high quality receiver that came standard with your unit. Note: If you want to charge all your receivers at the same time, you will need to also purchase a charging cradle (#TT1236400)for each receiver you add. For every two charging cradles, you will need one dual charger (#TT1245300). Does not come with a collar strap.
