This 12v DC Croc Clip Adapter allows you to connect your PAC Pet Fence Control Unit directly to car battery terminal clips for power. The cable is 6ft/1.8m in length. Ideal when you are on the move (in your campervan, motorhome, caravan or tent) take your PAC Pet Fence System with you. Pull some boundary fence wire through a garden hose, so when you get to your holiday home or campsite, just lay out the hose in the shape or around the area that you want to contain in (if moving location in your camper, just roll up the hose until next time). Secured the dog fence wire using standard Plastic Tent Pegs. Our top tip is to charge the dog collar fully before you leave home as it is less likely you will have to charge it again while on the move.
