GPS position works really good within 5-10ft. Details on the maps are really good havent had any mishaps yet. It does have one of the lakes I wanted(lake Nippissing), but does not have the other 2 smaller but not so small lakes.
My only complaint would be the smaller lakes arent even on the map, If they were I would map them myself, but they dont even show on the map( trout lake, lake nosbonsing) north bay Ontario. Where these lake are it just shows roads!
Wish they would show, otherwise great app!
