NAVIONICS PREMIUM OR LAKE INSIGHT PRO V14 ?
Hello Dominator...I recommend the Navionics mapping card. Navionics gets 2000 daily updates. I fish S/E Wisconsin waters and I record sonar logs on all waters that I fish and then upload those logs to the Navionics website making the maps even better. I also have the #Navionics mobile app on my phone which is awesome for only $10. Good luck my friend.
