Dogtra EF-COLLAR (extra collar for Dogtra EF-3000)

The Dogtra EF-Collar is used with the Dogtra EF-3000 Gold system. It features a rechargable battery and is capable of five different correction levels. The collar is also one of the few that vibrates as well as beeps to warn the dog they are getting too close to the boundary. This makes it useful for older dogs that may be a little hard of hearing.
