I don't have firm pricing yet. The series of sonar units are called the Mark and Elite. The Mark is a Gray Scale view and the Elite is a color view. The Mark-5x DSI I a DownScan Imaging Fishfinder. The Elite-5x DSI is a color DownScan Imaging Fishfinder. The Elite-5 DSI is a DownScan Imaging Fishfinder/Chartplotter.
Notice that the "x" in the model number indicates that the unit is a sonar only unit, no GPS.
The GPS model is the Elite-5 DSI. It has a micoSD media card slot that accepts the most up-to-date mapcard options including Fishing Hot Spots Pro USA, LakeMaster and Navionics Gold Charts. It also has an internal GPS antenna but has a coax input for an external GPS antenna if you so desire.
The Elite-5 DSI Gold DownScan Imaging Fishfinder/Chartplotter is preloaded with special-issue Navionics Gold microSD chartcard with coverage of coastal/offshore US, Canada, Alaska, Hawaii and Bahamas, plus detail for the Great Lakes and over 125 major Canadian lakes.
