I have a full set of Raytheon instruments.
Wind, tridata, depth, knotmeter, compass (yes, the fluxgate compass
sensor), countdown timer, and more. It even tells me the water
temperature in fahrenheit and celsius. The compass reads in true or
magnetic. The wind instruments read in true or apparent.

Standard stuff. The Raytheon instruments won't tell you:
