I have some working KVH instruments to sell: 1 - multi functional digital display; 1 - Quadra brain box; 1 - Analog wind direction; 1 - Knotmeter through hull; 1 - Depth through hull; 1 - Masthead unit, needs the plastic cups replaced and the pointer replaced, but worked last season. . I know how hard it is to keep these old instruments in service. I also have two or three extra displays that don't work, but perhaps are good for parts? If anyone wants these, it will take me a bit of time to get them off the boat (it's winter here in the Midwest!) Thanks, Jim Schrager; [email protected]
