I have a new Furuno
sitting under the Christmas
tree as we speak...
It is Ipad/Iphone compatible.
There are currently TWO applications that can be used with it....The Furuno Marine
Radar App (Just a plane Jane radar return) AND now Nobeltec
The NobeltecTZ app allows radar output to overlay raster type charts
...It has some neat capabilities...3D, Raster charts
with (offline) Satellite
shoreline overlays etc.
There is a lot of talk about screen
(sunlight glare) but i dont plan to use it when the sun shines. I use an Ipad for a lot of my navigation
requirements. As you stated you were held up by"downeast" fog
...So did I this past summer (Stuck for 4 days...but fun).
I can state that in "bad weather" (overcast conditions) i have no issues with "Sun Glare" while using an Ipad...
Hope this helps...Haven't used it yet but i'm confident it will fit my bill..Coastal Cruising and if the forecast
calls for bad weather
..I can stay put.
