A fish finder device housing (10) having a watertight shell housing (10) capable of containing an electronic load having a transducer within an interior space, the housing (10) have oppositely opposed extension members (24, 26), each of the extension members (24, 26) having a keel (25, 27), the oppositely opposed extension members (24, 26) and keels (25, 27) helping maintain the fish finder device housing (10) and contained transducer in a stable condition such as in a substantially upright vertical position and preventing the housing (10) from rocking back-and-forth and rolling side-to-side during normal fishing conditions including choppy or wavy water, when an angler is fishing in a body of water having a current, or when the angler is pulling the fish finder device housing behind a watercraft during trolling. The fish finder device housing (10) may have an aperture (29) in at least one of the extension members for connecting a fishing line, such as that of a fishing pole, or a line for tethering the fish finder device housing (10) behind a watercraft. |
