How It Works

It comes with the XNT 9 SI 180 T which is a transom transducer which supports 200/83/455 kHz frequencies,  but it doesn’t support elements from 800 kHz in the transducer.  It has a built in temperature probe, which makes it to be one of the best fish finder as it enables the head unit to indicate water temperature though it doesn’t offer a temperature graph function.

The transducer supports all types of sonar technologies that the display unit provides which include Side Imaging, Down Imaging, and Standard Sonar. The standard sonar can operate at 200 kHz with a narrow, more focused beam of 20 ° while at 83 kHz  it has a beam of 60 °. Both beams are conical shaped. Since the unit supports DualBeam Plus sonar, both the views offered by the 200 kHz and 83 kHz beams can be observed in split screen, blended together separately thus says the best fish finder reviews.

Its sonar side Imaging, according to the  fish finder reviewsoperates at 455 kHz, working with two side beams, 84° each, covering a surface of 240 feet on each side, 480 feet overall . As for the down imaging, the unit actually uses the side imaging beam  to create one beam for the down imaging. The beam is fan shaped and razor thin fore to aft and wide from side to side. The side to side width of the DI beam can be modified

How Does It Navigate

It has an internal Precision GPS receiver which uses WAAS for correction. This offers a fast position fixed with an accuracy within 2.5. Waypoints, routes and tracks with this HELIX, it has these functions covered. It can store up to 2,500 waypoints with 45 routes with 50 WP each.  It has a track plotting function which is able to record your course in a breadcrumb manner, thus saving up to 50 distinctive trucks which are equivalent to 20,000 points each. It measures the boat’s speed via GPS.

It has a drift alarm and off course alarm. The drift alarm gives you the possibility to select a perimeter for your anchored boat and in case it drifts out of the perimeter, the alarm will sound. The off course alarm is similar to the drift alarm, only that the alarm will sound if you divert from your setup course.

How it Displays and Screenshots

It gets most out of its 7 inch display by use of a glass bonded lens which makes it possible to get a bright display that is easy to view in direct sunlight. It is oriented in the landscape mode making it possible to set the side imaging to use most of the screen to look for structure, while keeping smaller window for the GPS map.


The Humminbird Helix 7 Si is a medium unit which sells at a medium price. It is one of the best fish finder  in the market because of its navigation features. It has several upgrade possibilities available in the market to support superior mapping, other transducers and its software is upgradable.

Get to buy a fish finder after careful research. Buy one which fits your needs.

Its Frequencies – Multiple, Single, or Dual

What is the best fish finder when it comes to frequencies? It is a known fact that, dual frequency transducers come with both 60 and 20 degrees cones.  Frequencies are an important factor in transducers. The most common frequencies of transducers are 200, 192, 83, and 50 kHz respectively. When fishing in shallow waters, then the high frequencies of 200 and 192 kHz are the best. In deep waters, lower frequencies of 50 and 83 kHz is the best. So if going for commercial or professional usage, pick on the lower frequencies.

Best rated fish finders are those with high frequencies as they get more sonar waves being sent and received by transducers than the low frequencies that is what makes them to be best for shallow fishing as it will show more details up the screen.


When it comes to purchasing a fish finder, power is an important factor for best fish finders. A fish finder power is measured in wattage (W). If the wattage is high,  then your unit will be able to display readings faster, and it can read deeper, but if the wattage is low, then your unit will be slow in displaying readings and can only read in shallow waters. This is so because, the fish finder translates sonar waves it receives from the transducer and this requires power, if the power is low, then it will automatically be slow and the reading will not be clear. The opposite happens when the power is higher, the reading will be faster and clearer. So if you are going to fish in shallow water, then you don’t need a lot of wattage but if your fishing is to be done in a lake or salt water bodies, get the best fish finder that is more powerful.

It is good to remember that, best rated fish finder at 50kHz, for every 100 watts of power, will be able to show readings of up to 400 feet. Dual finders are the most mid range finders that are available in the market. This is because, when you use them, you are able to view frequencies from both end  in a split screen fashion i.e. 85/200 or 50/200.

Screen Resolution

For a fish finder to be rated as the best value finder, it must have a good screen resolution. The higher the number of pixels, the better the resolution. At minimum, the resolution should be at 240 (vertical) x 160 (horizontal) pixels.  For a quality sharp, crisp image, it is good to go for a higher resolution than 240 x 160 pixels.

The screen size combined with the screen resolution makes the ultimate factor for how clear your fish finder display will be. The cheaper units will have smaller screens, thus making them good only as a secondary or back up fish finders. For a main unit, it is good to go for the biggest size you could ever find and which your budget will allow. With a bigger and higher screen, you will be able to get a clearer picture because the numbers, data and echoes will be spread out and easier see and differentiate.

Black and White vs Colored Screens

Color screens are good as they allow for greater details and one is able to see millions of colors instead of 265 shades of grays from black and white screens. If you read best fish finder reviews,  you will learn that, most users have rated the color screens with a five star. This is due to the effect of the color screen to the fish and the under water, it brings them live on your screen. Color screens are easier to see in brighter light than black and white. When the weather is dull, color screen stand out.

Only go for the black and white fish finders if your budget cannot allow you to buy a color one. Otherwise, read the fish finder reviews and you will definitely go for a colored screen.


Sonar waves are received via the transducers. They then sent the sonar signal to the water and the underwater objects are bounced off and picked up again by the transducer. These data are picked up to the main unit which translates the signal into a picture that we can see and understand.

Best value fish finders  come with transom mount transducers out of the box. This type of fish finders is the easiest to mount and require very little installation. Thru hull are good when you have grown and your needs are growing.

Cones Angles And Beams

This refers to how wide of a beam is sent from the bottom of your boat into the water. It resembles an upside down ice cream cone. It is very thin and pointy at the top where the transducer is. The more further down it goes, the wider it becomes. The wider the degree of the cone the larger the area that is being covered.  The deeper it goes, the wider it becomes and the lower the sensitivity goes.

This transducer cone is available in the range of 9 degrees to 60 degrees with most of them being between 16 and 20 degrees. The best degree point to start with is 20 degrees as it is an excellent point that fish in different water depths.

One of the wonderful feature of a cone is, more than one cone can start to transmit from the same point. A standard transducer will have a single beam. As you advance,you can start using triple, dual beams onwards.  The more beams you have, the more water you can cover. If you are planning to go fishing in a lake, go for more beams.

Some best rated fish finders come with these beams, but others you have to upgrade. Though it will cost you more, but it will be a worthwhile cost.

Transducer Material 

Transducers come made of different materials and for specific fish finders. Those which come with plastic, transom are the best. It is good for casual or sport fishing and it is compatible with most of the boats available on the market, except the pontoons where you will have to mount the transducers somewhere else.

If you happen to use a thru-hull or in-hull transducers, then you will have to use the plastic housing for fiberglass or metal hull. For aluminium or steel hulls, stainless steel housing is recommended. For wood or fiberglass, bronze housing is recommended.

Speed and distance are features on some units and which are important in trolling as it will help you to tell the speed at which you were traveling when the fish strikes.  Make sure to have a temperature gauge on board as it will help you find warmer water or locating an ideal temperature for the type of fish you are trying to catch.

Most best rated fish finders have GPS as it helps in case of an emergency. Every boat needs a GPS to provide coordination or help get the trip back home. Using the GPS and some apps,you can be able to draw own maps if you frequent an uncharted body of water or fish on a small lake. You can use programs such as LakeMaster Maps or Lowrance Insight Genesis. Both programs are compatible with Humminbird 1100, 900, 800 and 700 series.
