Buying Guide– best fishfinder GPS combo under $300

Best Fishfinder GPS Combo Under $300

If you are finding it a hard task to find out which best fishfinder GPS combo under $300 is suited for your needs, the following can help you know what features to look for.


Ask yourself first how you intend to use the fishfinder. Will you be installing this device on the motorized boat? Will you be mounting it on a kayak or canoe? Do you need it for trolling? Will you be utilizing the fishfinder when casting from the shore?

If you are an angler with varied techniques, you will be fishing in freshwater and saltwater and even occasionally fish in ice holes during winter. You will need a flexible unit that is made to withstand a wide range of severe environments. It is also an added plus if it is equipped with a classic flasher for ice fishing expeditions.  


There are tons of fishfinders on the market. How you intend to use your particular unit will dictate the best type of fishfinders to purchase. There are fixed units you can install on boats. You can also fix castable fishfinders to a fishing line and cast to scan a difficult to access spot without scaring off the fish. Hand-held ice fishing fishfinder will have built-in classic fish flashers. If you need a fish sounder, you can utilize a map to know your route and mark favorite fishing spots. In this case, you will need a fishfinder with GPS features.


The transducer is the technical part of the fishfinder. It is the component that sends out soundwaves underneath the surface and gets the sonar reading. It is crucial to check the type of transducer in the fishfinder you are considering purchasing. The three factors to consider in a transducer are its operating frequency, cone angle, and wattage.


The operating frequency shows you how deep or wide the transducer’s solar signal sends as its travel in the water. High-frequency signals such as 200 kHz will transmit a more exact and accurate image of the area that is directly underneath the transducer. A lower frequency signal, such as 83 kHz, can scan a wide area. If you are fishing in shallow and deep waters, go for a design with dual or multiple operating frequency capacity.

Cone Angles and Beams

The location covered by the solar beam the transducer transmits is cone-shaped; the cone angle is the angle in which is solar signal is sent from the transducer device. When the angle is larger, the wider the beam will be, and a larger area is covered. Some beams can penetrate deep into the waters. A dual-beam coverage will provide you the best of both cone angles.


The wattage indicates how powerful a fishfinder is and how quickly the signal is emitted and travels through the water. The greater the wattage, the higher the power, and the deeper and faster the signal can travel. If you’re fishing in deep waters, you will need to utilize a powerful fishfinder with high wattage as much as 4000 Watts to send out signals to greater depths. 

Display Screen Resolution

It is not a big deal how sophisticated the transducer technology is if you cannot see and interpret the data displayed. Therefore, the display is one of the most crucial parts of a fishfinder, and screen resolution is vital when selecting a fishfinder. The greater the screen resolution, the better the quality and clarity of the image.

Display Screen Colors

A color display is not only vivid and pleasing to look at; it also makes it easier for you to read and see more details about what is underneath the water compared to a simple black and white screen. It is also more effortless to pick out the fish and find out targets on the bottom structures. The best fishfinder GPS combo under $300 can show hundreds of colors. 


Fishfinders need a power source, and it is crucial to confirm what you will be able to provide for your unit wherever you will be using it. Some Fishfinders are fixed, and you can install them on a boat and connect them to a power source. When it comes to portable units, some can be powered by disposable batteries while others have rechargeable ones.


If you need a fishfinder, which can be mounted on a small watercraft and can be carried in any place and held in your hand as you venture from area to area, a portable fish finder that is small and lightweight is ideal. Some portable options even come with a protective carrying case
