Animated Tide and Current Indicators
You can view indicators for animated tide station and current direction on the
Navigation chart or the Fishing chart. To do so, information for tide station
and current direction must be available in your preloaded map or BlueChart g2
Vision region. You must also select the Animated value for the Tides/Currents
setting ( page 11 ).
An indicator for a tide station appears on the chart as a vertical bar graph with
an arrow. A red arrow pointing downward indicates a falling tide, and a blue
arrow pointing upward indicates a rising tide. When you move the cursor over
the tide station indicator, the height of the tide at the station appears above the
station indicator.
Current direction indicators appear as arrows on the chart. The direction
of each arrow indicates the direction of the current at a specific location on
the chart. The color of the current arrow indicates the range of speed for the
current at that location. When you move the cursor over the current direction
indicator, the specific current speed at the location appears above the direction
indicator.

Detailed road and POI Data
BlueChart g2 Vision contains detailed road and points of interest (POI) data,
which includes highly detailed coastal roads and POIs such as restaurants,
lodging, local attractions and more. For instructions on searching for, and
navigating to, these POIs, see the “Where To?” section beginning on page 22 .
Using Automatic guidance
Automatic Guidance automatically creates and suggests routes based on
available BlueChart g2 Vision chart information. See page 47 for instructions
on setting up Automatic Guidance for your boat.
If Automatic Guidance must calculate a route close to potentially dangerous
points, those points are outlined in red, and a message appears informing you
that there are potentially unsafe areas along the calculated route.
The “Where To?” section on
page 22 has additional information on how to use
Automatic Guidance.
