TI-503 SV

This compact unit measures just 5 by 3 by 0.5 inches and has a +/- switch key to simplify entering negative numbers. The 7-millimeter-tall character display is easy to read, and the soft large keys are comfortable to operate. The sizable eight-digit display is not sacrificed to the small size. Easy to use when traveling, in the kitchen, classroom, or home office, the TI-503SV is so economical you can have one in each room. Plus, an automatic shutoff feature conserves battery life.
