Best Cheap Fish Finder

Here is a list of the Best Cheap Fish Finder

Top Five Best Cheap Fish Finder

1. Garmin Striker 4 Bbuilt-in GPS Fish Finder

Going for the fishing expedition is one of the most adventurous activities I never miss. I usually make sure that I have the right GPS fish finder can help in improving the chances considerably. It comes with a high power which enables faster unit display of results and can get an influential reading in short time. It also comes with with a higher sonar frequency which provides the much-needed side and down imaging as well. A GPS based fish finder uses a simple tool based on certain features like basic depth and temperature information relayed in 3D maps which facilitate the fish catching activities.

2. Garmin Fishfinder 400C with Dual-Beam Transducer

The Garmin 400C Fishfinder is another equipment that worked well for me. It includes a clear, ultra-bright, 4-inch, full-color QVGA screen, Operating at 320 x 240 pixels of resolution. The clear display helps you separate the fish from the floor, and the debris is floating in the water and on the bottom.

With its one-touch navigation system, it is simple to use the front panel control buttons to change the various functions. And its patented "UltraScroll" even allows for screen updates at live-action speeds.

At night and in low light settings, the 400C has a backlit keypad and a night mode feature so you can just keep on fishing. By selecting between the dual-beam or dual-frequency transducers, the 400C can be quickly adapted to either saltwater or freshwater fishing.

3. Humminbird Helix 7 Fishfinder/GPS with Dual Beam Plus Sonar

Most of the sonar units of the fish finders operate at 192 or 200 kHz (kilohertz) with some using 50 kHz. Hummingbird fish finder models with DualBeam PLUS Sonar operate on both frequencies. You will have to match the transducers frequency with that of the sonar unit, which simply means that 192 kHz frequency sonar units require a 192 kHz transducer to get the best out of your Hummingbird fish finder system. Sonar units that operate on high frequency (192 or 200 kHz) give the best resolution and capable of giving images that are easy to recognize.

4. Eagle Cuda 350 Fish Finder

Eagle Cuda 350 Fish Finder

Rating: 4.0 / 5.0

In case you are looking for a portable device coupled by GPS technology, Eagle Cuda 350 is the perfect pick. It weighs less than two pounds, so you carry the item along with you. It also measures 11 by eight by 4 inches, so you find a free spot on your boat.

As mentioned earlier, it has built-in GPS and mapping system. It takes pride of GPS and WAAS receiver plus detailed mapping of US Coastal waters. It also features advanced internal antenna to improve reception mechanism.

5. Fishing Buddy 140C

On top of many other Humminbird portable fish finders, the Fishing Buddy 140C takes pride of 256 Colour TFT display screen. That can give you a better glance on fish targets and bottom structures. And it comes with no ordinary transducer tube. It takes pride of the extendable transducer tube that can go as long as 40 inches. That makes it ideal for use in small and mid-sized boats. The best part is that the unit only weighs 1.3 pounds so you can practically take it anywhere you go. Nonetheless, it is further stuffed with SideFinding Sonar technology.

Favorable Features of these fish finders

Display Screen

Monochrome or Color - Color is great, but if cost is a concern, the color does not affect the accuracy.

Screen size - the wider the screen, the larger the viewing area.

Water temperature sensors - on screen display for surface and underwater changes.

Audible/visual alarms - for bottom fish or water temperature changes


Portable or Fixed-mount - Portable units are entirely self-contained and usually include a carrying case and suction cup transducer hardware. Example: Eagle Fishmark 320.

Dual or Single Frequency Transponder

Dual frequency - has both 50KHZ and 200KHZ sonar and is used for very deep water or salt water. It will penetrate better in the dense salt water and give a better signal in water over 200 feet deep.

Single frequency - uses only the 200KHZ; used in inland lakes and fresh water and under 200 feet depth. Example: Lowrance X67C.

Temperature gauge

Water temperature greatly affects the behavior of fish. Fish are cold blooded and assume the temperature of the water around them. In lakes, there are warm layers of water and cooler layers. Where these layers meet are called thermoclines. Many times bait fish prefer the areas above the thermoclines while the larger game fish prefer in or just below it.

GPS option - Global Positioning System

Your need for the GPS option will depend on where you fish. If you often fish in unfamiliar locations, GPS is a great security feature. It maps out your waypoints so you'll always get back to camp, even at night in the dark or around complicated structures and islands.
