Now added to the PalmScale 8.0 is the Hydro-Hinge lid, which has been a highly requested feature. Simply press the "open" button and the lid opens on its own. A stainless steel weighing tray adds to the sharp looks and durability.PalmScale 8.0 has been loaded up with extras. You now get two expansion trays, one small and one large, you also get a black vinyl carry pouch, a tweezers and spoon set (stored in the scale itself) and a calibration mass. My Weigh's Weigh Meter technology comes standard and provides a visual bar graph on the display showing you how much of the scale's maximum capacity is being used during weighing.
