Small Boat Radar Buying Guide

Best Small Boat RadarsWhen buying a radar for your small boat, there are several things to keep in mind to ensure that you are getting the exact product that would help you safely navigate the waterways while also serving specific functions that are unique to your boating goals.

One of the crucial factors to consider is the power of the radar that would suit your boating needs. If you sail on waterways more frequently at night or early in the morning, there is a need to opt for radars with a higher power of 4kW and above. This increase in power translates into a broader radius coverage.

Furthermore, your purpose of boating may influence your choice of small boat radars. Some small boat radars are equipped with a sonar system that helps to locate fishes while a few others are Chartplotters. It would be more productive to get a sonar system radar if you frequently use your small boat for fishing.

Although small boats are not always high, they are of various sizes and heights. The small boat radar is supposed to be mounted at the highest point of the boat, where it will not be obstructed for utmost efficiency. Also, installing it at the highest point of the boat prevents people from being exposed to the waves being emitted by the small boat radar. Therefore, it is essential to pay attention to the length of the connecting/scanner cable or, in case of wireless connectivity, the coverage distance.

Finally, small boat radars are made with two types of technology. Some are the older, traditional pulse radars, while others are solid-state or broadband radars. We recommend the solid-state or broadband radars because, unlike the conventional pulse radars that use magnetrons, they use FCMW technology or CHIRP sonar systems. As a result of this advanced technology in solid-state or broadband radars, they emit little to zero radiations, thus are eco-friendly; have better target resolutions; quick pick up time; high maximum ranges; and flexible installation.
