Default Garmin TOPO comparison

With all the garmin marine gps units , the option to put in a garmin TOPO map card opens up the quality of maping available for inland less detailed coastal areas

Here's a side by side comparison of the g2 built in marine maps in a Gargin echomap 70s and the same unit reading from a topo map card. these mapcards are for all over australia
here is an example of coastal waters. on the built in g2 maps. some depth soundigs appear and a general idea of the shape of the lakes/islands are present . rivers are marked with a basic line

with the topo map , you loose the depth soundings, but gain far more detail on rivers. lakes. shapes of the coast line. even major roads/forrest areas
and an in land comparison
on any unit. a blank screen awaits most units. or a very very crude outline (unless you live in the US)
