GARMIN 010-00460-00 FISHFINDER 140 GPS Marine. 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 do not 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 Garmins new fishfinders.

User Reviews about Garmin Fishfinder 140 with 4.7-Inch Display and Dual-Beam Transducer

This was just what we wanted to replace our old fishfinder! With Fast delivery . -- Best price around!

Delivery was as expected. Product was as expected. No surprises. Life is good! -- Everything as expected

This fish finder is what it says it is. A basic entry level unit. With that being said I think it's somewhat better than just entry level. Having several settings that can be adjusted and changed left me feeling better in control of the information I recieve. Like that! Large, clear info with sound(beeps). The display is easly viewable in direct sunlight and is backlite for night. Comes with mounting bracket that turns and tilts but is not heavy duty. Off shore rigs might want to upgrade to a stronger mount, but for the lakes in TN it seems to be just fine. Only bad thing to say would be the size of the transducer plug. The plug is way to big! Cutting a 1" hole into a transom is not for the weak at heart. Then had to come with a large sealing gromet, sealant and large clam shell. None of which is included. Over-all, very pleased! I really like the water temp and voltage display. Unit seems to be well worth the money invested. -- ...Pleased...

The Garmin fishfinder is exactly what it says it is...a fish finder. It responds accurately when bottom is relatively solid with limited weed clutter. However it often loses the bottom...even at relatively shallow depths when the bottom is muddy or has weed growth....this is not uncommon for these types of units...however when the 140 loses the bottom I have to shut it off an restart in order for it to work again. It works well as a trolling depth/fish finder but is of limited value as a depth finder at speeds over 30mph. Overall, for the price, this is a good Fish Finder. -- Good Fish finder

I'm no expert when it comes to fish finders. However, this unit was easy to operate and it gave depth readings that matched the chart that I was following. When I got into very weedy water, it tended to show a lot of fish (when fish recognition mode was on). However, for the most part it seemed to give an accurate reading and showed the structures that I expected to see.

Also, the screen is easy to use, the buttons are easy to operate, and the menu seemed intuitive. I'll get around to reading the instruction manual sooner or later, but the default settings seemed to work just fine.

With some modifications to this item (http://www.amazon.com/gp/product/B0009PCP6I), I was able to have a nice, portable fish finder. -- Worked well.
