Lane Width—adjusts the width of the course line drawn when navigating. This setting also affects routes (Route To), but does not affect automatic guidance (Guide To).

Using Fish Eye 3D

Using the depth contour lines of the BlueChart g2 Vision cartography, Fish Eye 3D provides an underwater view of the sea floor or lake bottom. Use the Range keys to adjust the view.

Note: You must have an “s” series unit (such as a GPSMAP 526s) and a transducer wired through a marine network to receive sonar information.
