The Garmin Striker 4DV comes with a 3.5-inch HVGA Color display. It has a pretty good resolution of 480 x 320-pixels. Also, the most important thing is that it comes equipped with an integrated GPS system. Although the resolution seems poor, it’s quite good considering the size of the display. The CHIRP and DownVu are two innovative technologies which make this fish finder a unit worth checking out.


- Capable of dual frequencies

- 2D sonar with CHIRP

- GPS with high sensitivity

- Ability to save up to 5,000 waypoints

- Affordable


- No unit cover included

- Lacks NMEA connectivity


Garmin Striker 4DV includes the CHIRP transducer which provides a higher level of clarity and detail for fish and terrain below the deck than traditional sensors which work on the same frequency. CHIRP sends a continuous sweep of frequencies instead of sending just one wave of frequency. People often tend to think a lot about purchasing particular products. It’s easy to get over your budget, especially with fish finders.

That being said, the first thing you need to determine before buying a fish finder is what do you need it for and what auxiliary features do you require. When you categorize your demands, it will become much easier to choose the right one for yourself. In this review, we’ve tried to pay attention to some technical stuff as well as evaluate the overall quality and performance of this fish finder.

Why is GPS Important?

Having GPS integrated into your device offers a lot of possibilities. Although GPS isn’t a necessity, it’s certainly an upside. With GPS you can mark waypoints, areas with high concentration of fish, and track your movement. GPS comes in handy when you’re fishing in unfamiliar waters because it’s almost impossible to get lost if you have this feature integrated into your fish finder. You can also analyze the movement and the migration of fish. So, not having a GPS function can be a burden, people often purchase additional GPS devices, and install it separately.

By having GPS included, you save money and time. So, whether you’re an experienced fisherman or an amateur one, GPS is a thing you need.

Experience the CHIRP and DownVu

CHIRP sonar technology can create crisper fish arches with greater target separation. Also, CHIRP offers a visibly higher level of accuracy and detail than traditional transducers. As we said, CHIRP sends a continuous wave of frequencies instead of just one at the time thus providing a better quality of picture as well as more accurate readings. You can also upgrade to high-performance CHIRP technology, which provides a crystal-clear sonar image with even more target separation and resolution from shallow to deeper depths.

DownVuSonar offers a nearly photographic image of what passes deep below your vessel. You can clearly see the terrain, fish, structures, and objects on the bottom. CHIRP sonar and DownVu scanning sonar are combined into one transducer. A higher frequency like 260 kHz creates fine details but with less distance.

Display and the Resolution

The display is 3.5 inches of diagonal width. It’s not an extra-large display by any means, but it’s more than enough to allow you to determine various readings accurately. What’s important is that this fish finder comes with a color screen instead of a black and white one.

The resolution of 480 x 320-pixels is relatively good for the size of this display. Every object is easily distinguishable on this display. So, although the resolution seems underwhelming, it’s quite good nonetheless.

DownVu and CHIRP send accurate signals back to the screen to provide the best possible visual representation of what’s happening in the water.

Other Useful Features

We can’t talk about useful features and not mention the GPS feature. Tracking your movement as well as the movement of fish is crucial for successful fishing. More importantly, GPS allows you to mark spots where the fish are biting so you can return to the same place again in the future.Use the waypoint map to view, mark and navigate to locations such as brush piles, stumps, and docks. It’s also a useful tool for finding your way back to the boat ramp, or the harbor.

Also, you can check the speed of your boat with Garmin Striker series. It helps you make sure you’re cruising at the right speed for the bait you’re using and for the particular fish you’re following.
