I have a DT Systems R.A.P.T. 1400 set of collars. I have the transmitter and two collars. This has been a great collar for me. I am just upgrading to GPS collars. I would like to get $150.00 for the entire set. This is the all black system. Both collars are black and one has a black module and one has a camo module. You can reach me here or by phone. 314-435-2527 call or text. I can ship and accept paypal or other forms of payment. Let me know if you are interested. Thanks!
