Sold my last year with 2 coils and got enough for a new CTX3030. Kind of figured the prices would drop with the XP2 out and manticore coming. Didn't know about the 700/900. Going to stick with the XP2. I personally don't see anything in the published specs on the 800 or Manticore to dump the XP2. Love the wireless headphones and pinpointer. Makes life a lot easier when recovering targets. Really got to not like the swing harness for the CTX.
