Another form of range control is Zoom. The Zoom menu allows three different settings; Zoom Off, Zoom On, and BL or Bottom Lock. Zoom allows selection of various ranges for full screen viewing, not necessarily including the surface. By using the display to view a smaller area, the effective display resolution is increased, and the units ability to separate targets close together is enhanced.
