I have a GPS designed for road and off-road use, that runs OziExplorer for off-road.

I'm chasing boating charts for this unit that are compatible with OziExplorer. The cheapest option thus far is downloading and conerting/calibrating the maps from the Moreton Bay Marine Park User Guide.

Whilst it's nice having the zones, the charts aren't really detailed enough, and don't actually cover all the areas (the hundreds of metres gaps between the different maps).

Short of scanning my Beacon to Beacon (will take forever!), can anyone advise what electronic charts might be available?
