Map Page showing boat cruising Puget Sound, Washington (left) with

Overlay Data turned on. This example shows Depth, Ground Speed

and the Steering Arrow. Note that the Steering Arrow always points

directly to the destination you are navigating toward. In this case, the

boater is headed on a northwesterly course of 275º. Since the helms-

man is on course, the Steering Arrow is pointing straight ahead. If the

boat veered off course, the arrow would show which direction to steer

to get back on course. Sonar Page with Overlay Data turned on (right),
