What Are Fish Finders and What Can You Do With Them?

Fish finders are sonars with display screens that allow fishers to see a graphic portrayal of what is below their boats so they can recognize fish. To select a fish finder, look at the type of unit – does it include GPS and is it a part of a boat-wide network, size of the fish finder’s working range, resolution and size of the display, the amount transmitting power you need, and what frequencies will work best in the inland, coastal or deep-water conditions where you like to fish.

Basically there are three types of devices available:

  • Standalone fish finders that serve no other purpose. If you’re on a budget and want to see what’s below the water, dedicated finders give the biggest display and the most performance for the smallest cost. Perfect for small boats and small lakes.
  • Combination finder products that also contain a chart plotter. These models are suitable for most mid-sized boat owners. You can use GPS for navigation to the fishing area, view both on the split screen, or view only the fish finder. There are also transducer modules available for chart plotters. This is a receiver that mounts to your ship and it “collects” returning sound waves.
  • Fully-networked systems offering a large array of possibilities, all viewable through one large display. The features include radar, raster and vector GPS charts and graphs, video, satellite radio, controlling them through smartphone and so on. Multiple display support. New features are being introduced for more expensive models every year.


The larger the better, wide displays let you to see more useful details when you split the screen to display different types of data, such as your GPS chart, depth, frequency, radar screen, or data from transducers.


This is power of the fish finder device. The strength of the ping signal is stated in watts. Smaller lake anglers can see the shallow bottom with just 200 watt (rms) equipment. A 500-watt fish finder has enough power for most coastal uses. A truly serious fishers should look for 1,000 watts or perhaps even more. The higher the wattage, the faster your device can show readings, and the deeper your readings can be. The lower the wattage, the slower it will be, and is better suited to shallower water. That is because your fish finder reads the sonar waves it gets from the transducer.


Typically, higher frequencies provide the best and precise resolution, minimum background noise on the display and the best look from a fast-moving boat, but don’t pass through as deeply as lower frequencies. Low-water inland fishermen usually choose higher frequencies, say 200kHz, 400kHz or 800kHz. For highest possible depth, lower frequencies are advised. We suggest 200kHz or higher (as much as 800kHz) for water depths up to 200 feet(60 meters) and 80kHz or 50kHz for deeper waters. Some models allow multiple frequencies showing unbelievably detailed images and let you switch between them for wider, more general views, and narrower, more precise views of the waters under.

Fixed or Portable

For more established fishers and boat owners, a fixed finder would be a better option, it can be set in a fixed position on a boat. If you like to ice fish or travel around to fish, a portable fish locator would be more suited. MUUTA — Most of the models come with the transom mount for installation. The portable units come with the transducer already attached to the transom with the use of a suction cup.


Humminbird HELIX 5

Although the Humminbird HELIX 5 G2 shares much of its features with the HELIX 10, it has fewer functions and a reduced screen size. It also costs less.

The fish finder is waterproof and well-built. It has a large 5 inch color WVGA display. You can navigate the menu using raised buttons that are organized in an ergonomic, comfortable way. Side and Down Imaging are used by the HELIX 5 to provide a clear rendering of what is happening beneath the water’s surface.

Advanced imagery is created using Humminbird’s 2D sonar technology and CHIRP technology. The CHIRP frequencies can be accessed at a maximum depth 1000 ft and provide wide angle view. This fish finder uses two methods to cover the largest frequency range possible. It can produce more detailed maps and identify fish faster.

This fish finder’s processor quickly analyses the data and relays the results in real-time with AutoChart Live, Humminbird Basemap and other similar cartography tools. The HELIX 5 can also be used as a GPS device by utilizing the most recent maps and data from NOAA/LakeMaster to show reliable information on the weather. The HELIX 5 can be used for navigation, way marking, and write don points of interest.

With regards to power output, the Humminbird HELIX 5 has an output of 500 Watts RMS..

Every HELIX 5 model comes with a transducer. Standard equipment for the GPS G2 model includes a transom-mounted XNT9 20 T transducer. Additional accessories include all necessary mounting hardware and a mounting bracket for the gimbal.

The large screen also makes it much easier to see from a distance or to check out the digital readings from both GPS and fishfinder all at once.

This is a great fish finder tool for budget-minded anglers.
