As the technology evolves rapidly, it goes without saying that fishing, as we know it, is also changing seriously. This is something that you should take into account.

Using contemporary technology allows both beginner and professional fishermen to identify the best spots and to channel their efforts towards them.

This particular device aims to do just that in order to enhance your performance and to spare you the unnecessary hassle of having to look for appropriate spots on your own.

Main Usage

The unit is only suited for boat or kayak fishing as you need to mount it conveniently. This is not a cast-type sonar fish finder and this is something that should be accounted for. However, there are quite a few different applications that you can go for.

With this in mind, it’s also worth noting that it’s more suited for beginner to semi-pro fishermen. The reason for this is mainly within its overall composition. It’s an affordable unit, which makes it lacking in certain ways. At the same time, though, it’s worth noting that it’s likely to be the best you are going to get for this particular price tag.

The overall features are convenient but it seems as if they are mostly tailored for more entry-level fishing undertakings. Now that we have conveniently covered the basic introduction, let’s have a look at the more serious characteristics which need to be taken into account.

Product Features

Beams and Cone Angles:

Now, the 197C DL is a model which is capable of conveniently generating two distinct beams. These are going to get emanated from the transducer. This particular device is actually going to create one beam which is narrower of 16 degrees. This is going to supply rather sharper details of the items which are located directly underneath your boat.

The other beam is the one which is more functional. It is created at the same time and it has a cone angle of 28 degrees. The deeper span is going to include a lot more objects. However, as you may suggest, the level of the details is also going to be lower mainly because there are going to be current disturbances as well as slit which is stirred-up and it’s likely to be captured.


The frequencies are two as the transducer operates on dual-frequency settings as you can figure out from the double-beam capacity. Obviously, the first one is going to be a lot higher, which is going to function in shallower waters to provide high-quality readings.

It’s set to about 200 kHz. On the other hand, the 80 kHz frequency is designated to create a wider 28 degrees cone angle in order to capture the units which are located deeper under water.

 As we mentioned above, this is also going to create a picture which is a bit more distorted in comparison but it would provide you with a yet clear picture to consider.


Screen Resolution:

The capacities of the screen of the sonar are also of great significance. Right off the bat, the display is 5.6 by 3.9 inches and it’s about 1.3 inches deep. This makes it a rough 3.5 inch LCD monitor which comes with a resolution of 320 x 240. This is going to provide you with a very detailed picture.

The more detailed the picture is, the larger your chances of getting the most accurate information are. That's mean you can ensure that you identify the intensity of the located school fish, how many fishes there are, what speed and direction they are traveling towards and potentially the type of fish as well.

To any semi-experienced fishermen, this information will mean the world as it will allow him to determine the lure type, bait and the overall utilities to take into account.


Regardless of what you may think, the colors are also quite important. This particular one comes with 256 hues of color which is going to attribute to the aforementioned detailed picture. This is definitely something to take into account. Older models used to come with only black and white capabilities and a lot of noise on the screen, which made them a lot less efficient in comparison to the contemporary solutions which are currently available on the market.


All in all, the truth is that this is a great entry-level sonar which would provide you with a very serious performance. Of course, it can’t be compared to higher-end console types but it’s getting closer than most of the units available on the market.

The thing which makes impression is that it manages to combine a lot features in a very convenient manner which allows serious performance while the price is kept relatively moderate in comparison. Sure, there is a lot more that you can potentially ask for but given the price, this is truly the best you are going to get.

If you want to ensure that you have no issues with your fishing trips ever again, this is one of the units that you might want to take into serious consideration.
