Does anyone know where I can get a Garmin Blue Chart (SA) for a GPSMAP178 at a reasonable price? I was quoted R3000, but I'm sure one should be able to get it cheaper than that.
I agree 100%, makes live on the water much easier. I bought my Garmin 298 Chartplotter Fishfinder Combo and charts on a stick over the net for R8000, postage included. Money well spent.
"Bluecharts" can only be used on certain Garmin chartplotters, the maps contains the same info you will find on a SANS naval chart and more. All depends on the model chartplotter that you own.
