petsafe wireless containment system 2 collars large small

Description

Pet safe underground fence wall unit system and 2 collars / one small and one large
Collars have been washed but could stand replacing (you can put the units on any collar - just need to punch holes)
Large collar takes 9V battery; small takes disc batteries - comes with 2 - one new and one in collar
You just need a spool of the wire and it’s ready to install
They work fine - just have too much area to cover so we upgraded to a gps collar
