Let us discuss some of the greatest features of the device.

Ease Of Use

Do not expect any hard time when you are using this fish finder. It has a user-friendly interface, and this makes it perfect for beginners and professional anglers. The device has simple menu settings and controls that provide you with a great time. Additionally, you will get a manual to help you learn all the controls of the fish finder for easy operation.


The display of the device is amazing. It has a large LED display that provides you with the best vision without straining the eyes. The screen measures 5 inches, and this gives you a clear view of the images. The screen has a high resolution with 320×240 pixels so you can easily see all the details of the images. You read the screen under any lighting condition because it has backlighting.

You should also note that the screen is black and white featuring grayscale and this will help you differentiate fish and other structures and objects found in the water below the boat.


Apart from using it like a fish finder, it also functions as a chart plotter. It has a built-in GPS antenna. This GPS system is very accurate in providing you the details on the current position of the boat. You can easily mark important spots so that you can always come back. The device is also compatible with Navionics Premium and Fishing Hotspots. It also has a micro SD that you can use to upgrade to the new cartography.


As compared to other fish finders in the same price range, this unit has a high power output of 2100 watts. This brings about a quick output, and you can also see sonar results in deeper waters.


Mounting this fish finder is easy. You can choose to mount it permanently to your boat or use it as a portable device. Installing the device is simple because it comes with a quick-release mounting system. It also has a tilt and swivel bracket that allows you to use it as a portable device. You can also flush-mount the fishfinder using the accessory mounting kit.


The fish finder comes with a transducer with dual-beam sonar which is great. The sonar will help you get more details on what is happening under the water, and it becomes simple to detect any fish that might be present. This means that it can support two different frequencies that you can choose depending on your situation. It has the 83 kHz frequency with a broader cone angle and gives more coverage underwater. This makes perfect for fish detection. The second frequency is the 200 kHz which you can use to detect the bottom structure in shallow waters.

TrackbackTM Scrolling

The TrackBack feature allows you to save all your recent sonar history so that you can access it at any time when you need to. This means that you will find it easier to access your previous fish targets, transition, and structure. You no longer have to keep tracing back your path after leaving the fishing spot. All you need to do is to move the cursor through your sonar display history.
