Navionic's ap for Iphone

[harvey lee]

Was thinking about buying this ap for my Iphone. Does it have good maps or mostly 5ft contour map's?

It has good contours,it just depemds on what lakes your looking for as some lakes are just the generic dnr versions of the map, the high def lakes you can only zoom in so far so if the contours are really close together it can be tough to tell what depth you are at with it.It is definately better then nothing tho in my opinion.

They have a mix, some are good and some are just the DNR maps.

Luckily you can check whether your lake has decent contours or not by going to their web app -- I can't post a link but if you google "navionics web app" it's the first result.
