Garmin Livescope Plus

Garmin is the pioneer of real-time live sonar technology. They introduced their LiveScope in 2018 before other notable competitors like Lowrance and Hummingbird launched their respective products. Being the first to introduce such technology often provides an edge in terms of market understanding and product refinement.

Garmin’s LVS34 transducer, which is part of the LiveScope Plus system, offers a beam size of 20 degrees by 135 degrees, placing it at a competitive advantage in terms of coverage. The frequency range is between 530 to 1100 kilohertz, which is on par or even superior to competitors. Moreover, the range of up to 200 feet sets a benchmark for others to compare against.

When it comes to the actual imaging, it provides the most detailed images in the real-time sonar market. This implies that users can expect clarity and precision when looking at underwater objects and fish in real-time.

The Livescope’s LVS34 is noted for its impressive performance, especially when it comes to its perspective mode. In comparison with the Lowrance Active Target’s scout mode, particularly in shallow water applications, the LVS34 excels. This distinction is crucial because shallow water environments can be particularly challenging for many devices to render accurately. The engineering behind the LVS34 allows it to perform exceptionally well in these conditions, which is a testament to its advanced technological capabilities.

However, one minor issue we found is beam stitching, which sometimes can be noticeable on the units and may slightly affect the user experience. Beam stitching refers to the visible lines or seams where two different sonar beams overlap and merge.

In terms of pricing, it is the most expensive live sonar system. However, the difference is minor compared with the Lowrance Active Target system.

Humminbird MEGA Live

mega live units

Humminbird’s MEGA Live, launched in 2021,  is the latest addition to the real-time sonar options. 

In terms of technical specifications, the MEGA Live offers a range of 150 feet, which is 50 feet less than what Garmin and Lowrance offer. However, for practical purposes, especially in the forward or overhead views, users rarely go beyond this 150-foot range. 

The MEGA Live maintains the same beam angle as Garmin’s offering at 20 degrees. Yet, it narrows the beam width to 120 degrees, compared to Garmin’s 135 degrees. 

In terms of frequency, the MEGA Live operates at 1050 kilohertz. Interestingly, despite having the “MEGA” name, its frequency is 50 kilohertz lower than its competitors. 

When it comes to the clarity and detail of the live sonar, MEGA Live doesn’t seem to match the standards set by Garmin and Lowrance. Although it has addressed and resolved the beam stitching issue that can sometimes be observed in other units, its overall detail level doesn’t quite reach the standards of its main competitors.

However, Humminbird has made significant improvements in the mounting system for the MEGA Live. 

The product features a hinged landscape mount that stands out for its simplicity and compactness. Users can easily adjust the mount by pinching two buttons and rotating it. This hinged landscape mount is arguably the most user-friendly and compact overhead view system currently available in the market. 

When compared to the mounting systems of Garmin and Lowrance, the MEGA Live’s mount is noticeably more compact and doesn’t have any knobs that users need to be wary of potentially loosening. This ergonomic design enhances the user experience, making the installation and adjustment processes smoother and less cumbersome.

Lowrance Active Target

Lowrance launched its real-time sonar option, Active Target, in late 2020. This was after Garmin had already introduced its LiveScope in 2018. The introduction of Active Target meant that Lowrance was joining the ranks of brands providing high-detail real-time sonar options for users.

In terms of technical specifications, the Active Target bears similarities to Garmin’s LVS34 transducer. While Garmin’s beam size is 20 degrees by 135 degrees with a frequency ranging from 530 to 1100 kilohertz, the Active Target has a slightly narrower beam size at 18 degrees. The 2-degree narrower beam theoretically offers a slightly more detailed image. However, based on the observations, there is no significant enhancement in the sonar image of Active Target over Garmin’s LiveScope.

When it comes to image quality, both Garmin and Lowrance have demonstrated the capability to produce higher detailed images in comparison to Hummingbird’s Mega Live. This indicates that Lowrance’s Active Target is among the top performers in the market in this aspect. 

In deeper waters, the Active Target shows its prowess by effectively capturing underwater structures, providing a continuous and clear image. Comparing with Livescope, which offers a broader picture due to its wider beam, the Active Target provides a detailed representation, especially of objects closer to its beam or focus. 

However, it’s noted that there’s a slight delay in the Active Target’s update rate when compared to Garmin’s LiveScope. This means that while Active Target offers high-quality images, its refresh rate might be a tad slower.

Our Verdict: Livescope vs MEGA Live vs Active Target

All three brands have their strengths and offer high-detail real-time sonar options. 

Garmin’s LiveScope provides most detailed images and is seen as a leader in the market.

Active Target is closely matched in performance with Livescope. It is effective in specific scenarios and provides detailed images, especially in deeper water contexts. 

Hummingbird’s MEGA Live boasts seamless integration with boat components and has an advantage in installation, but falls short on image clarity.


What is Live Sonar

Live sonar, often referred to as real-time sonar, is an advanced form of sonar technology that provides near-instantaneous underwater imaging, allowing users to see fish and structures in the water in real time. 

Traditional fish finders provide a snapshot of what’s happening beneath the water, and these images are refreshed at intervals. On the other hand, live sonar provides a continuous, real-time view, much like watching a video.

Live sonar technologies offer a level of resolution and clarity that rivals medical imaging techniques like ultrasound. This allows for the identification of fish species based on their outline, which is not always possible with conventional fish finders.

One of the most significant advantages of live view fish finders is the ability to see how fish react to your lures. This can provide invaluable insights into the fish’s behavior and improve the angler’s technique.

Live sonar can produce 3D images of underwater structures, like sunken ships or rock formations. This gives a better spatial understanding of the area you are fishing in.

Beyond recreational fishing, live sonar can be used in research, marine biology, and even in search and rescue operations due to its ability to provide a clear view of underwater objects.
