Shane, I am running 2 LCX25C's as dedicated GPS units. I am running 2 Elite 7's as sonar and DI. I will be running a structure scan HDS 5 as a dedicated side image unit when i find a used one. My 25's are getting full of waypoints and will start dropping some of them if not already done so. I had talked to lowrance about the insight but was confused as to the part about mapping. I thought they said that after you created a map, they would sell you an encrypted version. Was trying to avoid ongoing purchases when i get to the mapping part in the future. Right now i am just wanting to get started in managing the waypoints by lake name and saving them to a card but have some sonar recordings also. Hope that makes some kind of sense, not sure if i explained it correctly. Thanks.
