The refurbished SonoSite SII is the second-generation point-of-care ultrasound in the SonoSite S-Series of portable ultrasound machines.
The used SonoSite SII design departs slightly from the previous S-Series ultrasound machines by its size and user controls. It is about 3 inches taller than the original S-Series and 2 inches thinner. It adds 4 pounds of weight (12.6 lbs) and has more intuitive controls. The SII is completely flat-panel and has an overall different look and feel than the original S-Series ultrasounds.
