Updated Features:
- Support for MEGA Live Imaging™:
Get must-watch detail and non-stop action. MEGA Live Imaging is a powerful sonar technology that will help you find and catch more fish. Connect to any SOLIX or APEX model and you'll see fish in real-time, allowing you to learn what makes the fish want to bite.
With no gaps in sonar coverage and industry-leading MEGA Imaging clarity throughout the entire view, you’ll see more fish, in greater detail than ever before.
Find where the action is. Mark and view waypoints right on your MEGA Live Imaging screen and return to the spot later.
MEGA Live Imaging Views
- Support for 30% / 70% split screen views:
Vertical split-screen views can now be changed form a 50/50 split to a 30/70 split.
This can be done with any application combination with the following rules:
The Video In/Out pane is not supported.
Instrument Views and the RADAR view only support 50/50 split.
Side-Imaging, 360 Imaging, and MEGA Live must go into 50% and 70 % panes. They cannot go into 30% panes. This means that Chart, 2D, and DI are available for the 30% pane.
