Garmin Striker 4 Fish Finder

Great value fish finder with GPS

The Garmin Striker 4 is a compact yet feature-rich fishfinder built around Garmin’s CHIRP sonar technology. Equipped with a 3.5-inch (480×320 pixel) colour display and a dual beam 77/200kHz transducer, it delivers crisp and highly detailed underwater images. By sweeping across a range of frequencies, CHIRP enhances target separation and clarity - allowing anglers to distinguish fish arches, structure, and bottom contours with impressive detail, even at high trolling speeds.

A standout feature of the Striker 4 is its built-in high-sensitivity GPS. This feature allows users to mark and save up to 5,000 waypoints - spotting their favourite fishing zones, docks, ramps, or any other underwater features of interest—and easily navigate back to them using the waypoint map interface. You can also monitor your boat’s speed in real time, which is especially helpful for trolling at optimum speeds. The device is tightly integrated with Garmin echoMAP chartplotters, allowing waypoint sharing between units.

User-friendliness is a key strength. The unit operates via a simple keypad interface with large, intuitive buttons that even work when wearing gloves—no touchscreen needed. Real time sonar history rewind lets you scroll back through previous scans to identify fish or mark a hidden waypoint missed in the moment. 

The Striker 4 is highly portable, weighing just around 230g and small enough to fit in a tackle box. Rugged and waterproof to IPX7 standards, it can withstand splashes or brief immersion in water up to 1m deep.

In summary, the Garmin Striker 4 offers outstanding value: a compact, durable unit packed with advanced sonar and GPS features usually reserved for higher-end models. Its portability and easy operation make it perfect for beginners and experienced anglers alike across kayaks, small boats, or frozen lakes. While it lacks built-in mapping (though waypoints can be shared with echoMAP units), and the screen is modest in size, it remains a standout choice for delivering professional-level functionality in an accessible package.
