Marine charts on Garmin GPSMAP 78sc

Hi

I just got a 78sc that has built-in bluechart maps. When I zoom out i can see the depth info and depth zones. But as I zoom in they disappear. I used Navionics on iphone before and when you zoom in you can still depths info. Why is it gone with the bluecharts? Are they less detailed?

Cheers

All good. After playing around with all the settings I could find it turns out this is due to the fact my gps also has an inland map which at closer zoom overlays on top of the marine maps. Disabling it allowed all the depths info to show up.

Cool, because mine didn't do that! I like the Garmin maps!

Yeah I kind of like it too. I like the Navionics Sonar map and its cheap when using with iOS app ($24 per year) but I always end up killing my iPhone one way or an other when kayak fishing... So it ended up more expensive than buying a dedicated gps
