I'm rigging my yak and the next purchase is a fishfinder. I would prefer one with a GPS. Right now I'm looking at the Lowrance Mark-4. It's the "cheapest" fishfinder/gps unit they offer. My question is, which brands, features, and styles are working best for you? It seems the more I research, the more confusing it becomes. There are so many different technical specifications I feel you need to work for NASA to figure out what to get. My requirements are Durability, user friendly, and works as advertised. I don't need the really fancy high end stuff. I just want it to work. Also, does it matter what kind of transducer it comes with? I've seen transducers specifically made for through the hull applications, but it seems most use the transom style and mount it inside the yak. Does that make a difference, for all practical purposes? I don't need super fancy or high tech, just a plain jane F150 type of model that will get the job done. I'm also red/green color blind so color gradient is meaningless to me!! It looks cool, but gray scale is easier for me to distinguish.
I've kicked around using a separate GPS or phone, but I'd prefer it to all be on one system. To much stuff to keep track of and I have a bad history with cell phones.
Primary fishing will be our 80 acre neighborhood lake (max depth 18 ft), second area will be Lake Lanier (max depth 150ish and average of 60 ft), and third area will be surf launch near Grayton Beach. Max depth about 100ish ft.
There is so much to choose from. Just trying to get some feedback and see what people are using and what to stay away from.
