Similar question to kernow. Looking at the cheaper range of plotters and several mention built in charts such as simrad and lowrance with insight, also Garmins charts. Question is are any of these charts usable for uk coastal navigation?
I have a Garmin 451s on my RIB. The screen is a bit small and the charts of UK waters can be a bit grainy. It is adequate for navigation but I would go up a size. I only use mine for a cheap depth sounder and speed. The maps are a useful comfort. Touch screens are problematical if mounted in the open in the rain or heavy spray.
