The Best Fish Finders Under $400
The ongoing development of state of the art fish finder GPS units that establish way-points and incorporate fastidiously accurate fish finding data continues to change the face of sport fishing as we know it.
Never before has it been so easy to find and pinpoint the exact location of productive fishing spots, and then save that valuable information for future use.
Add to that the ability to constantly monitor the water temperature, locate fish in high definition and also use mapping software showing detailed fishing information for virtually any given locale, and you have the ultimate tool for putting you on the fish in just about any situation.
It is then up to you to actually catch and land them!
Every angler has their own preferences, but when it comes to the best fish finder that sell for under $400, my personal choice is Hummingbird Helix5 CHIRP GPS G2. It offers a degree of sophistication that was previously only available in units that cost much more.
Here are a few things to consider when looking for the right fish finder in this price category to fit your specific fishing needs.
The Best Fish Finders Brands To Consider
While you can certainly find a variety of fish finders on the market these days, there are presently only three major manufacturers that offer consistently reliable units that cost under $400.
RMS transmit power (W)
GARMIN STRIKER 5DV
HUMMINBIRD HELIX 5
Lowrance Hook 7
750 feet (salt) 1,600 feet (fresh)
They all possess a full range of features that run the gamut from providing basic depth and temperature data, to offering sophisticated side finding capability and detailed 3D images that are portrayed in vivid color.
Key Design Features of Fish Finders
Because of the nature of their design function, several similarities exist between these basic fish finders. They possess 12 channel parallel receivers, can determine, save and recall way-point information and can create routes. A combo fish finder GPS unit is much more affordable than purchasing the two units separately, and it gives you the same operating features and double the technology all rolled into one.
There are basically two important things that you should consider when selecting a new fish finding unit. The first is resolution. LCD screens are made up of numerous pixels that combine to make a single image. Thus, pixel saturation will determine the sharpness of your screen image. A pixel count of 720p is considered High Definition, and will provide you with optimum resolution and detail.
The second is power. For saltwater application, always look for at least 250W of RMS power and 3000W peak to peak, which will allow you to plot deeper water. Another consideration is screen size. While a handheld user may not have a lot of choices in this category, those buying standalone pieces for the console should look for a minimum screen size of 5” and work up from there, depending upon their budget.

Final Note on Fish Finders

Nonetheless, it must always be remembered that these units do not actually catch fish for you; they simply help you locate them.
