I have the Garmin Montana 600 with Marine Bundle for sailing and kayaking in the ocean. I bought the TOPO US 100K so that I can also use it for hiking. I now have the BEST for both land and sea. If I zoom in to be able to see the trails in detail, I must first go into MAPS and disable the Marine map since the marine map takes precedence since it's already loaded onto my GPS and the TOPO Map is on a micro SD card. I don't have enough memory in order to be able to see both in detail at the same time. I'm going to use the Marine map when I go whale watching tomorrow with the kayak, and the TOPO map when I go hiking in Yosemite in the snow next month. I love my Garmin Montana. It's simple to use and their Customer Service is outstanding!!!
Great topo map set for hiking.
