Hey guys, my girlfriend just got me a Garmin GPSMAP 62s and i have a question. I plan on mainly using it for fishing south Louisiana marshes. I'm trying to find out a decent marine topo map to either purchase from Garmin or download from here. Just not sure whether to just get the 100k topo that comes with the 62st or try for the south central marine map. Just interested to see if anyone has purchased a garmin marine map and whether they're satisfied with it/worth the money. Thanks!
