There was, at last count, over 500 anchorages/harbours covered in detail with Antares and in reality most locations you might head for on the west of Scotland is likely to be covered. In terms of operating in a small area, it's relative, I would rarely do more than 150mls in a day but even at that we've been to every populated island off the west coast of Scotland except Barra and visiting places like Loch Teacuis and the head of Loch Hourn was a lot easier with Antares.
As I said, I wouldn't advocate using a tablet or laptop as a substitute for a plotter but there is no technical reason that a plotter couldn't run third-party charts as well eg. inland lochs. (Navionic's Loch Lomond is very basic and I don't think the Garmin recognises it at all.)
For some reason they allow additional charts to be loaded on handheld plotters but not fixed ones so this isn't a technical issue.
Ok I misunderstood, thought you meant using antares only
We have toured with another boat who had antares & a raymarine we had garmin & it didnt make much difference to be honest I couldnt see that the antares gave him much advantage over the detail we had.
I guess the first manufacturer who makes a plotter compatible with any chart format & able to switch from one to another will be on a winner
