What is the best/preferred electronic map for Lake Murray for striper fishing (as well as fishing other SC/Ga lakes)? I almost never fish on the coast, so that is not as big of a concern for me right now. I have an older Navionics HotMap Premium East SD card that I used in my Lowrance LCX gps/sonar unit. Is that still the preferred electronic map or is there something newer and better?
Also, if the HotMap Premium East card is still the preferred freshwater map, will my older Navionics HotMap Premium SD card work in the newer Lowrance HDS Gen2 Touch Units or do I have to get a different type of card?
Finally, if I can’t use my old SD card and have to get a new electronic map, how can I transfer the fishing spots I have stored to the new unit and map?
Thanks for any guidance and advice.
