Garmin FishFinder 140 Review

4 min read

The Garmin FishFinder 140 is one of the most affordable and easy to use fish finders available.

It is loaded with a wide array of high tech features that help make locating fish an easy and intuitive process.

Easy To Read Screen

The screen is much easier to read than other fish finders thanks to Garmin’s new 240 vertical pixel screen that has four levels of grayscale. It is far easier to make out what is being displayed because of the much improved contrast and image separation.

Clear Targeting

The dual beam transducer sonar technology allows for targeting clearly even in water as shallow as one foot deep. The viewing width of the Garmin FishFinder 140 can be switched between fourteen or forty-five feet. Every feature of this fish finder is geared toward improving visibility and ease of use.

Easy To Use

When people first buy the Garmin FishFinder 140 and finally have the chance to test it out, they are often extremely impressed with how easy it is to use. It almost makes it feel like cheating. It is that easy to set up and use.

Ultra Clear Screen

The screen is ultra clear and it is very easy to make out targets. I am simply amazed at the speed and accuracy of this unit. Because of its affordability as well as the features offered, I highly recommend this fish finder.
