Thank you everyone for the input. I just sold my Standard Horizon black box fishfinder on eBay so it is definitely time for something new.
I was hoping that the Garmin map would go more than 6 miles inland. With the C-Map I have been using I can go all the way up the Penobscot to the dam in Bangor and it goes up the Kennebec past the bridge in Augusta. I am looking at the Lowrance and Garmin units. I have friends in a local bass club that use Navionics lake maps because they do offer some of the lakes in Maine and it has been adding new lakes every year. I really want something with a screen around 7 to 8" in size, so when I use it in split mode you can see both really well. That was the 1 thing I really like with the Cp1000C, 10.4" screen, but I figure seeing my gauges is fairly important.
Please keep coming with info, the more the better!!
