Finding the best fishfinder that will fit your needs can be challenging. As value is everything, the Garmin Echo 100 is a strong fishfinder that is packed with all the important functions without the hefty price tag. What makes the Echo 100 stand out is the crisp 4-inch display with an 8 level greyscale FSTN screen and 160 x 256-pixel resolution. The Garmin Echo 100 can quickly extend to its single 200 kHz beam transmitter that works to bring even the smallest details hiding in less than 600 feet of fresh water.
Due to the compact size, the Garmin Echo 100 is ideal for small-to-mid-sized boats. Everything you need for a fishfinder is included in the box. Along with the fish finder itself, the box also includes a tilt and swivel mount, the necessary power cables, transducer and manual instructions.

To increase your chances of catching fish, the HD-ID target tracking technology makes it easy to easy what goes on underwater and what you should catch. This unit provides a great separation between images with quick refreshers.
The 4” display screen is quite moderate for a model of this price, but it works nonetheless. Compared to other units in its field, it is quite superior due to the 8–color greyscale screen, making it capable of displaying sudden temperature changes. The depth reading abilities are excellent as the screen provides depth readings and depth of the catch below. This is incredibly handy when you look for fish that prefer to stay in certain temperatures or when changing temperatures that cause an increase in oxygen.
The screen is easy to see in sunlight, in order to stay useful no matter where you use it. This screen also provides 2D imaging along with the black and white feature that works well as there will be no colour to distract in the light.

Combined with one of the best screens in its category, this factor makes fish finding and locating structures quite simple.
As with all Garmin products, the Echo 100 unit is readily installed with the latest in HD-ID technology. This means that capturing fish patterns and arcs is incredibly detailed and simple. The scanning range of this unit is in-line with similar products in the category. This unit operates at 60 degrees -10db to provide a large enough arc of the scan while allowing you to stay mobile on the water.
As one of the best in its field, the transducer is able to tell the difference in temperature within the body of water. This brings vital importance when it comes to fish finding, which is also something that the Echo 100 manages with ease. While the suitable hardware is standard, a supporting bracket and a trolling motor camp can be attached to the unit. The transducer has a frequency of 200 kHz with a cone angle of 60 degrees, making it ideal for large bodies of water.
Despite the great features, this unit provides within its budget, the power unit is surprisingly low when compared to other units in its price range. The unit runs between 10-20V while in operation, as 100W is devoted to the sonar unit.
We like the portability style model like the Echo 100, as it is beneficial to anyone on a small boat and knows the value of space.
