For sale is an excellent set of Tri Tronics Classic 70 training collars with transformer, battery chargers, and 3 collars. Comes with carrying case, all paper work, and each collar and transformer has a new battery installed. I am asking $225.00. A one collar set sells for $320.00at Cabelas and each additional collar is 130.00 so your talking $580 plus tax. You can email me at [email protected] or call me at 810-537-1879.
