In very good condition, hardly used. Includes instructions. For remote control of Nikon cameras (F3, FA, F4, F4S, F70D, F801, F801S, F501, N2020, F301, N2000). Has exposure meter switch- depressing trigger halfway activates camera's exposure meter, 31" cord, and trigger lock lever for long exposures. I no longer have the camera it was used with which is the reason I am selling it. Internet list prices range from $60 to $110 for a new one.
