Slow to the point of being unusable

The slightest move on the chart causes a 5-20 second wait for the map to redraw itself. Zooming out makes the map unreadable for at least as long. Simplifying the map only helps a little bit...still too slow to use.

The charts are way too busy graphically speaking-very hard to even find a channel with giant marker icons.

The only good thing is that is coordinates with boat beacon, a very good app.

Get Navionics. 1000 times better.
