Well, we been using a Comnav 1001 for 10 years with one minor $50 repair.* It interfaces well w/ Coastal Explorer & Northstar, handles following seas, easily adjustable and has steered us from WA to AK and back (about 20k nm).* I'd buy another for the next boat.* It's also nice to know that it is still in production.* FYI most of the local and not so local fishing boats have them installed.
