I have a PetSafe 3/4-acre wireless fence system and a 1/2-acre extender I bought in Jan. of this year and I no Longer have a need for them. The 3/4-acre system comes with the transmitter. and 110v power cord , collar and charger, 40 ish boundary marker flags and instructions. Cost was $300 +tx. The 1/2 acre extender comes with the transmitter and 110v power cord . Cost was $214 +tx. They worked great and collar would go a week on a charge and it is waterproof. I have pics on my phone and as soon as i figure out how to transfer them to my laptop I will add them. Both systems cost me $514 + tax and I will not separate unless the extender goes first. Pm me if you have any questions Thanks BB ( will ship on your dime)
