Garmin Striker 4 Review


The Garmin Striker 4 comes with a 4-pin connector transducer. It is dual frequency-capable.  It uses a conical beam of 15° for 200 kHz and another of 45° for 77 kHz.

On top of that, you can use a 50/200 kHz transducer if you want to scan deeper as the control unit itself is capable of 50/77/200 kHz.

The only downside is that it’s mid and high CHIRP-capable, which means you can’t use low CHIRP with it.

Scanning Depth

With the Garmin Striker 4, you'll be able to scan up to 1,600 feet deep in freshwater and 750 feet deep in salt water.

However, the unit may be unable to scan deeper than 800 feet without a 50 kHz-capable transducer.

CHIRP Sonar Technology

You’ll get more power and clarity to your images thanks to the CHIRP sonar that the Striker 4 is equipped with.

This includes better-defined targets, a better lock to the bottom, and less clutter.

On top of that, it provides the user with superb target separation. So even if there are a lot of fish sticking close to each other, you’ll be able to see each individual fish for its real size instead of seeing a big blob as a target.

Besides the split-zoom and alarms, there are a couple of functions associated with the CHIRP sonar technology including:

Fish Symbol ID

Fish Symbol ID is a function that analyzes the sonar returns in different ways and assigns fish icons to returns that the unit will interpret as fish.

Moreover, it shows you the depth at which each target fish lies.


The Ultrascroll feature enables the sonar data to scroll faster to keep up with the pace of high boat speeds.

However, even with the Ultrascroll feature, at speed exceeding 40 to 50 MPH, the images you see would probably lose some of their quality.

Auto Gain

With Auto Gain turned on, you can adjust the unit to automatically filter noise that you don't want.

Flasher Mode

The Flasher Mode is a circular depth scale that includes information regarding the targets caught by the sonar beams.

The inner rings of the flasher show you the depth while the flashing segments on the outer rings show you the different strengths of the sonar returns.

This feature really shines when it comes to ice fishing or stationary fishing.


The A-Scope function can be considered as a flasher as well but in a vertical layout.

It provides you with information about your most recent sonar returns.

Transducer Mounts

The transducer comes with 2 mounts: a transom one and a trolling motor one. It also has a 20’ capable and is equipped with a temperature sensor.

High-precision, Internal GPS

A downside to the Striker 4 is that it lacks a chart plotter or cartography.

So the GPS system would basically use a blank sheet for support.

The high-precision internal GPS module that's incorporated enables the user to mark 5,000 waypoints with several suggestive icons to return to.

This gives you the ability to re-visit your favorite fishing spots or spots that you’ve taken interest in.

However, it doesn’t provide you with coordinates information.

Display and Control

The Garmin Striker 4 comes with a 3.5-inch display of a 480 V x 320 H pixel matrix.

It’s an HVGA color display and features backlight to provide you with visibility to read it easily even in direct sunlight.

You can view 2 panels or applications simultaneously on your screen.

Design and Durability

The rugged design of the Striker 4 makes it quite durable and sturdy.

With an IPX7 waterproof rating, your fish finder will survive water splashes and rain without being damaged.

On top of that, it can survive immersion in fresh water up to 1 meter.

It comes with a tilt/swivel mount and power cable.


Although the Garmin Striker 4 doesn’t feature a microSD card reader or NMEA connectors, it does allow you to transfer waypoints between it and any echoMAP unit through the data cable.

Battery Life

On a single charge, the Garmin Striker 4’s battery should function for around 2 or 3 days.


  • Comes with dual frequencies
  • CHIRP 2D Sonar
  • Temperature-capable transducer
  • Plenty of sonar features
  • Highly sensitive and fast GPS
  • Capable of storing up to 5,000 waypoints
  • Easy to install, operate, and understand
  • Affordable price


  • Doesn’t come with a cover

Final Thoughts

The Garmin Striker 4 is a great option for a small boat or a kayak. It combines being compact, affordable, and practical.

While it doesn’t give you advanced navigation features, it also doesn’t make you spend extra on a down view sonar.
