Transparency
Use the transparency menu to adjust the transparency of menu win- dows. A high transparency allows you to continue monitoring the sonar chart while adjusting feature settings, though the text of the menus may fade until it is unreadable. A low transparency will usually make menu text easier to read, at the cost of watching your sonar returns.
Experiment with this feature until you find the right level of transpar- ency for your eyes.
