The better the abilities are, the better the safety is! So, select a radar that offers you all of them and additionally, GPS, SOS, and other emergency features.

After the features, come to the display. The display is not a major issue but if you have a better display like HD, then you will get some benefits like a better view. I said this because, in the daytime, sometimes you may have direct sunlight, if you have a high-resolution display, then you can get a clear view of any lighting condition. And yes, don’t forget to get one touch screen display. A screen touch display is more suitable to control.

Also, look for a mounting system. Choose one which has multiple mounting capabilities, because sometimes, you may need to change the position of the device.

Now, we will say about the autopilot system. Each radar doesn’t have this amazing feature, but which one has, surely is a perfect choice. Autopilot lets you relax and the program can run by itself. This can be your helper so that you can enjoy the time on the sea.

We finished almost all the important issues. This is enough to find a suitable marine radar. You may look for advanced options like frequency, receiver, channels, etc. but we don’t think that is too important. I hope, you can now find the marine radar that suits you most.

How to Maintain Marine Radar?

Well, not only the marine radar but also all the devices need maintenance. Proper maintenance helps to lengthen the device service period and keeps the best performance. As with other devices, the marine radar should be taken care of properly.

Here, we will discuss how to maintain marine radar. I hope, this will help you to get longer and proper service from your device.

First of all, regular maintenance is the key to keeping the device working longer. Try to keep the equipment as free as possible from dust, dirt, or water splashes always. Please make sure all the screws are secured and properly tightened.

The fuse of the power cable is to protect the equipment from the reverse polarity or ship’s mains over-current and the fault of the equipment. In any case, if the fuse blows, you better find the cause of the blow before replacing the fuse. Never use an incorrect fuse. It can be more dangerous.

Every month, check bolts for tightness corrosion. Replace the bolts or coat them with new bolts if needed. Look for foreign disposal materials such as oil, salt deposit, etc. If you get them, then clean them. They can accumulate the radio antenna that can make an effect on radar performance.

Check the waterproofing gasket for wear and open the scanner unit and check all the screws and board. Then wipe the screen and clean it with soft cloths and remove dust.

After 6 months, look out for the scanner motor brushes. A carbon brush usually serves for about 2000 hours, if the period is over, then replace the brush. The damage of carbon brush can make affect your display. It may show you damaged images. So, for safety reasons, replace it in time. And after one year, go and check all the board and wiring and make sure that they are secured. If you get any problems, then fix them.

Please note: The marine radar uses high-voltage electricity that can harm you. The voltage can kill a human with direct contact, so always power off the device before maintenance. Therefore, before starting the maintenance work, wait for two or three minutes to allow the residual charge to subside. The radio antenna uses a high frequency that can be harmful, especially to your eyes. So don’t be very close. Always try to keep at least 2 feet distance when you work with an antenna unit. It’s better to use the power of or keep the radio standby mode while working.

Mounting & Installation

You can easily mount & install your radar following the user manual provided by the manufacturer. But there are a few basic rules you can follow for mounting and installing.

After selecting your radar, find a suitable location for safe operation, maximum range, and minimum blind spots. The best space for the radar is the highest point of the powerboat. It can give the radar a 360° view without any interruption.

For mounting your radar avoid masts, stacks, horizontal spreaders, or any kind of solid objects because they create reflection, shadows, or blind spots.

Now mount the antenna above head- height. Because the electromagnetic energy emitted from the radar can be harmful.

If you are uncomfortable with the user instruction you can also ask for help from a marine technician.


The best marine radar serves much more than the worth of money. They are the best companion for you on the water. The modern multitasking radar allows you to do more efficient work with it. The advanced features ensure your ease and safety. They are always ready to support you as they are connected to the server. This is like autopilot. They can navigate the boat with automatic routing. The advanced sonar system and the nano receiver show you the right destination and unusual lands under the water. So, surely this is an essential kit.

If you are thinking of getting a new marine radar, hope this guide will help you. Because the radars I mentioned above are the best quality available in the market.
