Mine's not a portable. I am still rigging it on my canoe, but I'm eager to play with it.
They're not really fish finders as much as they are bottom finders. Oh sure, they'll identify fish, but the learning the structure of the lake bottom is going to be your big thing to learn.
My lake (I usually river fish shallow water) is man-made. There are sheds, roads, trees, bridges, fencelines, all sorts of things down there that will hold fish at different times of year and conditions. I'm eager to find them.
I may not even fish them that much. Most of my fishing at that reservoir is at dusk just beating the shoreline weeds with a grub to get away. Though I did catch my personal best largemouth bass at that lake, I'm usually a numbers guy.
