Which radar can detect non-metallic objects on the surface?

Hello, which FURUNO product can detect trunks of wood, boats, debris etc on the surface, and be connected to an autopilot that can also be used to avoid running aground? I am interested in purchasing this for a sailing boat.

Thanks

Most x-band radars can do that. It is a bit variable based on sea conditions because small floating objects bounce up and down in waves. Radar settings like echo averaging and echo stretch can help in seeing these types of "come and go" targets. Radars don't control autopilots. Plotters with mapping skills can. It sounds like you would be looking for a plotter unit that supports radar like a NavNet system.
