For years I pined for instruments. When I got them I found them to be not as great as I imagined. I do like a chart plotter (Like the Navionics app) and a VHF. But now that I don't own a boat I use mostly handhelds: VHF, hockey puck style compass, handheld anemometer, binoculars, and GPS. I take them with me when I guest crew, rent a boat or use one of the sailing center's boats.
The good thing about wind instruments, is that they teach you to judge the wind and after a while you don't really need them. If you race the speed (SOG and STW) are pretty much required. Wind angle is nice but a pencil or shroud with the dreaded cassette tape works too! They are a lot more sensitive and you don't need to look up as much which is nice for your neck and keeping your eyes on the race course is an asset.
