Traces Menu (on main menu)
A trace is a group of parameters (data) that describes the properties of the load and bullet you are working with. Ballistic Explorer can work with up to three traces at a time. At least one trace must be open to view ballistic data. Each open trace is indicated by a check mark next to it. Selecting an open trace closes that trace. Open traces can be brought to the foreground using the Windows menu.
