Garmin Echo 301c Fish Finder Review

Last Updated: 03.07.20


This is genuinely the best fish finder from Garmin thanks to its dual-beam transducer that is able to accurately map out the underwater environment and identify fish.

The fish finder is ready to go as soon as you take it out of the box.

The controls are well thought out and fairly intuitive so it should be easy even for inexperienced fishermen to operate it.

The device comes with a bright 3.5-inch color display that offers clear and detailed information that is easy to read even in poor lighting conditions.

The unit can be paired with a portable kit so you should be able to move it from boat to boat without any hassels.



The display size was deemed a bit too small by some users, however most agree it is sufficiently clear.

One of the Garmin Echo 301c fish finder reviews sadly notes that the detachable mount is made of flimsy plastic which may not be able to withstand a lot of abuse.

The device does not have GPS capabilities so it can’t be used for navigation, but this also keeps the price down.

Outfitted with an A-scope, the device provides real time display of fish passing through the transducer beam. The adjustable depth line shows depth measurements of underwater objects. The Ultrascroll® technology shows fish targets as the boat accelerates to a higher speed. Thanks to HD-ID technology, you can identify fish targets.

The fishfinder ships with a quick-release tilt/swivel mount plus a transom/trolling motor transducer mounting kit, so you can set it up on your watercraft right out of the box. It also comes with a power cable and documentation so you can install it instantly and get right to fishing.
