How To Choose A Fish Finder Under $300 – Buying Guide

How you intend to use the fish finder will determine the best fish finder under 300 for you. Will you be installing your unit on a motorized boat? With you be mounting it on a kayak or canoe? Do you want it for trolling? Will you be casting it from the shore?
If you’re a versatile angler who casts in freshwater as well as in saltwater and even jig through ice holes in the winter, you will need a versatile unit built to withstand a wide range of operating environment and equipped with a classic flasher for ice fishing.
There are different types of fish finders on the market. How you intend to use your unit will determine the best type of fish finder to go for. There are fixed units that you can install on a boat. Castable fish finders you can attach to a fishing line and cast to scan a hard to access spot without spooking the fish. And hand-held ice fishing fish finders with built-in classic fish flashers. If you want a fish sounder you can use to map your route and save favorite fishing spots, you will need a fish finder with GPS capability.
The transducer is the technical component of a fish finder. It is the part that sends sound waves below the surface and receives the sonar readings. It is important to check what kind of transducer the fish finder you’re considering comes with. The three aspects of a transducer to consider are its operating frequency, cone angle, and wattage as explained below.
The operating frequency tells you how deep or wide the sonar signal the transducer sends travels in the water. A high frequency signal such as 200 kHz transmits a more detailed and accurate image of the area directly below the transducer. A low frequency signal such as 83 kHz scans a wide area. If you fish in both shallow and deep water, go for a model with dual or multiple operating frequencies.
Cone Angles and Beams
The area covered by the sonar beam the transducer transmits is cone-shaped. The cone angle is the angle in which the sonar signal is sent from the transducer. The larger the angle, the wider the beam and the larger the area covered. A narrow beam penetrates deep into the water. A fishing sonar with dual-beam coverage will give you the best of both cone angles.
Wattage tells you how powerful a fish finder is and how fast the signals it emits travel through the water. The higher the wattage, the higher the power and the deeper and faster the signal will travel. If you will be fishing in deep water, you will need a powerful fish and depth finder with a high wattage such as 4000 watts to send signals to great depths.
Display Screen Resolution
It doesn’t matter how sophisticated the transducer technology is if you can’t see and make sense of the data displayed. The display is, therefore, one of the most important parts of a fish finder and the screen resolution is an important consideration when choosing a fish finder. The higher the screen resolution, the better the image quality and clarity.
Display Screen Colors
A color display is not only vibrant and pleasing to look at, it is easy to read and you can see more detail about what is below the water than you can on a black and white screen. It is also easier to pick out the fish and resolve targets and bottom structure. The best fish finders under 300 can display hundreds of colors.
Fishfinders require a source of power and it is important to confirm that you will be able to power your unit wherever you will be using it. There are fixed fish finders you can install on a boat and connect to a power supply. As for portable units, some are powered by disposable batteries while others have rechargeable batteries.
If you want a fish finder you can mount on a small boat, kayak or fishing canoe, carry wherever you go fishing or hold in your hand as you hop from ice hole to ice hole, a portable fish finder that is compact and lightweight is ideal. Some portable options even come with a protective carry case.

Q: How Do Fish Finders Work?
Fishfinders utilize SOund Navigation And Ranging (SONAR) technology. The transducer, which is the technical component of a fish finder, sends sound waves below the surface of the water. These sound waves hit fish and other objects underwater and bounce back to the transducer. Using the time lapse between when the signal was emitted and when it returns, images of what’s underwater are created and displayed on the screen of your fish finder or on your smartphone or tablet.Related Post: How To Read A Fishfinder
