When you're on a pile of fish, it's fun to share them with a fishing buddy, unless you have to do it over open VHF channels, where other anglers can hear you. But since the introduction of digital selective calling (DSC), the technology exists to transmit position data to, or receive it from, other DSC-equipped boats. So you can call your buddy using your VHF radio with DSC and instantly see his lat/lon numbers on your chartplotter and radio. And because your conversation is private when using a DSC radio, you can talk about where the fish are biting. Standard Horizon takes this technology a step further by working with C-Map to develop the software that allows your buddy to appear as a charted position on your plotter's display.
