Least expensive fish finder with extrenal gps antenna

Steve,

The NO GPS alarm within the Dragonfly displays cannot be disabled. Please note that the aforementioned ax8 MFDs and Axiom MFD also feature an internal GPS Sensor. For installations where the MFD will be installed in a location affording it an unobstructed view of the skies overhead, the unit should be able acquire and maintain a GPS position FIX ... unless access to the skies overhead is blocked by objects overhead (ex. bridges, boat shelters, dense foliage, etc.). In such cases, the MFD's internal GPS sensor may be switched OFF. This will prevent the MFD from thereafter producing a NO GPS alarm until the internal GPS is once again switched ON.
