This was fairly decent and a good backup to a sounder or dedicated plotter. However the recent iOS 8 update is not sitting well with this app. Aerial photos jump about the screen as you navigate. Not sure about the accuracy of other elements like bathymetry and gps location but seeing these all move randomly on the screen as you use does not I still confidence. Very disappointing on a product that is really expensive. Support was polite but completely ineffectual.
