Garmin Striker 4 Built-in GPS Fish Finder


The Garmin Striker 4 is the most compact in the Garmin line of fish finders. It has a 3.5 inch color display. This model is an easy to use fish finder since it has been painstakingly engineered to be operated by the simplest keypad buttons located right below the screen. These make it easier to navigate around the fish finder gadget that even those who are not tech savvy can easily find their way around and use it comfortably.

The gadget uses a 77/200 kHz CHIRP sonar transducer. CHIRP stands for Compressed High-Intensity Radar Pulse. This technology allows the transducer to transmit a range of frequencies instead of sending only a distinct pulse as used by those conventional fish finders. Using this will result in a clearer detail of what lies underneath the water.

The CHIRP technology built in the Striker 4 has a transmitting power of 200 W RMS/1,600W peak-to-peak. This may also be subsequently upgraded for better performance.

The unit also comes with a built-in, highly sensitive GPS which allows the fisherman to look for the fish, locate them and then mark their position. In this manner, the fisherman can return to the same area where the fish hot spot was found at a later time.

The GPS will also help make navigating back to the docks and ramps easier. The apparatus also includes a portable mount where the fish finder can be securely placed while on the boat. The mount can be tilted and turned for the convenience of the user.

Fish Finder Buying Guide

fish finder

Top rated fish finders are equipped with several advanced features that allow it to produce vivid and more accurate images. The following functions and applications need to be present in a fish finder to have the best value for your money.


All fishermen need the best GPS fishfinder for the money to help them navigate in the water and find their way home. This is also useful in providing the coordinates of any particular location whenever it is needed.

The GPS system will also help you create maps when you are fishing in unfamiliar places or uncharted waters. More modern ones also allow you to chart and produce maps for underwater terrain, fishing spots and provide other relevant fishing information.

Having the Right Type of Sonar

The best cheap fish finder is equipped with the right kind of sonar beams to create clearer images. There are three types of sonar, each having different functions and benefits.

First, is the Down Scan Imaging. This focuses on one particular spot, specifically the bottom portion of the area scanned. It is best when the fishermen seek to have a more detailed image of a specific area. The best depth finder uses this for surveying deep areas since it increases the precision of readings at around forty feet or even deeper.

Since this centers its scan on one particular area only, it is highly probable for the fishermen to miss other structures and activities that occur in the surrounding areas. In some shallow regions, there is a need to increase and adjust the signal in order to have a clearer image.

Second is the Side Scan Imaging. Using high frequency waves, the side scan allows the fishermen to take images of a wider area with only a single pass. Readings can also be made without going over the desired area since the scan can be done several feet away. This is highly advantageous in scanning undisturbed areas.

It is, however, less effective in deep waters, particularly those reaching from 75 feet or even deeper.

Third, combined down and side scan. This latest technology combines the two functions and provides a better option for fishermen. It works by sending two sonar beams, one focusing on a particular target and one doing a wide scan to cover the surrounding area. This allows the fisherman to experience the best of both scans.


Power is very important to ensure that the best fish finder is running accurately. Fish finders with the greater wattage produces images and readings promptly and with greater precision. This is especially useful in performing scans in deeper waters. Those with lesser wattage are more suited for the shallow waters.

This happens because the readings depend on the transmission of sonar waves received by the transducer. Therefore, when the total power used is greater, the readings are done much faster with more vivid results. Shallow areas also need lesser power to be scanned and detected.

Conventional fish finders utilize frequencies ranging from 50 kHz to 200 kHz. However, more modern types of fish finders are now capable of transmitting and receiving signals using a combination of a low and high frequencies or utilize multiple frequencies at the same time.

Higher frequencies mean that there are more sonar waves sent out and received by the transducer. This ultimately results to getting more images on the screen. Higher frequencies work best when fishing in shallow waters.

Lower frequencies, on the other hand, are more suited for general searches across a wide area in the water, including deep water explorations.

Most fishermen conduct a search using a lower frequency beam to identify various locations of fish groups. Afterwards, they narrow down the search by using a higher frequency to pinpoint a specific school of fish. In this manner, they are able to target the specific location of the fish and get a better haul.

The best fish finder will be able to combine all the appropriate frequencies in order to come up with a better picture and be able to target a specific area for a bigger catch.

Screen Resolution

The clarity of the images produced depends largely on the resolution of the screen of the fish finder. Higher resolution screens produce sharper images, while those with lower screen resolutions results to more fuzzy images.

The size of the screen will also play a big role in ensuring that the image seen on it is clearer, with more details easily identified.

Colored screens with higher resolutions are available in recent models of fish finders.

The best value fish finder will have transducers that are able to clearly translate and send the data it receives from the sonar transmissions. Transducers are the main transmitting units that send out and receive sonar waves. They function by sending sonar waves into the water, allowing it to bounce back from underwater objects.

These signals are then received by the transducer again and converted into images that are then reflected on the screens. Most of these are simply mounted on the fishing boats, with minimal installation requirements.

In selecting a transducer, it is imperative to check its corresponding cone angle. This determines the coverage that the beam is able to include in its scan. Beams with a wider angle will be able to include larger areas.

The only downside is that as the cone angle gets wider, therefore, its sensitivity also diminishes especially when it reaches deeper waters.

Transducer cones range from 9 degrees to more than 60 degrees. For fishermen who prefer varying water depths, it is better to start with a 20 degree cone angle.

The standard transducer only has a single beam. This can however be subsequently upgraded to having dual or multiple beams. An advantage to having an upgraded version is an increase in coverage. The more beams used will result to having more areas covered by the scans.


What is the best fish finder? It is one which has all the necessary features mentioned above that will fully assist every modern fisherman. This is a worthy and essential tool that will ensure that the fisherman is able to find the best areas for fishing at any given time. Knowing the essential features and characteristics necessary will help in ascertaining that the fisherman will get the best fish finder for the money.

Having a more modern and updated type these allow you to fully maximize the resources that are available. The best budget fish finder will work to produce accurate results and enable you to bring home a bountiful catch every time.
