The STRIKER 4 is very easy to use, especially for someone new to fishing. The color screen and GPS make it simple to navigate and find fish. The CHIRP sonar gives clear images of the underwater environment. I’ve marked several hot spots and returned to them successfully. Great value for the features.

I’ve used this fishfinder on both lakes and rivers. The 3.5-inch screen is bright and responsive. The sonar picks up fish clearly, even in murky water. The transducer works well with the built-in GPS. Would recommend to anyone looking for a reliable, user-friendly fishfinder.

The smooth scaling graphics make it easy to see fish and structure. I’ve used it for several days now and it’s been very consistent. The ability to save and return to hot spots is a big plus. No issues with the transducer or connectivity.
