When seeing your targets clearly is the goal, the Fishfinder 140 is the tool. With 240 vertical pixels on a four-level grayscale display, you get better separation and contrast. Like all of the new Garmin fishfinders, the 140 features Ultrascroll? for fast screen updates, which is ideal for speed applications. The 140 has minimal buttons and intuitive operations. You don?t even have to leave the sonar screen to change settings, thanks to a convenient adjustment bar. AutoGain, as well as user adjustable gain, is also standard on all of Garmin?s new fishfinders. Features include: 4-level gray scale FSTN Display, 3.3? H x 3.3?
