Used to fish Lanier a lot shooting docks pre-livescope and pre- good side imaging and the knowledge to use it. Lake has 10,000+ docks of which 1% hold fish consistently. That changes a little in the spring as fish move shallower. If you don't have or know how to use good electronics it's about spending time to learn your lake. I guarantee you you will find some docks that consistently hold fish and a hundred others that look just like it but don't. If you have side imaging as I read turn your range down so that when you scan the dock you can see the water in the black area not trying to pick them up on the bottom, if this makes sense. If I'm scanning a dock in 20' of water I will have my range at 30-40' and make a close pass, even less range on shallower docks. You will see them if they are there. Scott
