The 7-inch display is clear and responsive. MEGA Down Imaging shows fish details much better than older models. I can see structure and schools clearly even at 125 feet. The keypad is intuitive and works well in rough conditions.

Solid performance in real fishing scenarios. The auto-chart live feature helps track changes in the water. Only minor lag when switching views, but overall very reliable.
