Location: Warroad, Mn | Lake Master pretty much runs out of chip north of the Aulneau Peninsula. Once you get north of Whitefish Bay on the east side and north of the French Portage or Big Narrows on the West side you are off the charts. The charts are very accurate for location, but not real good for depth at times. It seems good for the lower half of the Angle area, all of the Sabaskong area and for Whitefish, but still misses a rock or three. Wouldn't trust them for full time navagation though many areas. Probably O.K. on the main routes. The Navaionics I have covers the whole lake, but it's older. The GPS accuracy of exactly where you are on the chart is not very good. It often shows you on land, when I'm pretty sure I'm not.
I'm not sure what the new Navonics chip has on it. I know they where charting the fall before last, but haven't seen the new chip.
Too many rocks on the LOTWs to really trust these things. I'd just go slow in areas that you don't quite know and learn safe routes.
Been there, done that!
