To show off its interfacing capability, our L1250 was linked to other onboard electronics via the Raymarine hsb2 (high-speed bus) networking system. One by one, we added additional information to the sounder screen, starting with data from the chart plotter. Now the course we had just followed was clearly visible on half the screen. Placing the cursor on a part of the course allowed us to access data for that particular spot, including depth, echo returns, bottom features and surface temperature. Next we added the radar, which allowed us to see radar images on one side of the screen, and either sounder or plotter info on the other. With a press of a button, we could even overlay the radar image on top of the plotter!
