Recently purchased Mustang 2150 with Lowrance Global Map 2000 GPS Sonar. Unfortunately as boat came from SA C-Map cartridge isn't useful on the east coast! Ideally would like to acquire an East Coast cartridge (C-Map) if possible.
Have researched new sounder combo options and would like any input on my following choices;
1. Lowrance LCX-27C
2. Hummingbird 900 series
3. Navman 8084
Any feedback re pros and cons would be great.
