Includes 8x9 and 5.75 concentric coils. I bought this detector new Aug. 2007 (have receipt) and used it until Sept 2010. Added extension wire to rear of arm cuff for headphone plug-in. The extension wire can be unplugged from the original jack on the control box and removed. Spray painted both coils green, didn't like white, too flashy. Coils can be sprayed white again. Detector works as it should. I rate it cosmetically at 6.5 or 7. Cortes is a good all-around machine but now I'm using a multi tone machine and so its got to go. (It has 9 tones when the SUM switch is pressed). For anyone who wants a Cortes at low cost I priced it at $280 shipped, CONUS.
