LiveScope vs. ActiveTarget vs. MEGA Live: Comparing the Big Three Forward-Facing Sonar Systems

Forward-facing sonar has completely changed the way many anglers approach fishing. Instead of only seeing what's already passed underneath the boat, anglers can now look ahead in real time, locate fish and structure, watch how fish respond to a lure, and make adjustments without having to make another pass over an area.

If you're building your first forward-facing sonar setup, however, there's a pretty big decision to make: Garmin LiveScope, Lowrance ActiveTarget, or Humminbird MEGA Live?

All three systems are built around the same basic idea, but that doesn't mean they're interchangeable. Each belongs to a different electronics ecosystem and comes with its own hardware, viewing options, compatibility requirements, and considerations when you're building a complete setup.

Despite what you might hear at the boat ramp or online, we don't think there's one forward-facing sonar system that's automatically best for every angler. The better question is which one makes the most sense for the way you fish.

What Is Forward-Facing Sonar?

Traditional sonar primarily shows you what's happening underneath the boat. Forward-facing sonar adds the ability to aim the transducer out in front of you and see fish, structure, bait, and even your lure moving through the water in real time.

Think about fishing a brush pile. Instead of driving over it, marking it, turning the boat around, and casting back toward it, forward-facing sonar allows you to locate that structure ahead of the boat. You can often see whether fish are around it, determine where they're positioned, and watch how they react when you put a lure in front of them.

That ability has made forward-facing sonar useful across a wide range of fishing styles. Bass anglers can target individual fish, crappie anglers can scan brush and suspended schools, walleye anglers can follow moving fish, and ice anglers can search a larger area without drilling a hole every few feet. Garmin, Lowrance, and Humminbird each approach that technology a little differently.

Garmin LiveScope

Garmin LiveScope is probably the most recognizable name in forward-facing sonar, and Garmin now has multiple generations of LiveScope technology in use on the water.

LiveScope Plus pairs the LVS34 transducer with Garmin's GLS 10 sonar module. It offers Forward, Down, and Perspective viewing modes, giving anglers several ways to look at fish and structure depending on how they're fishing.

One important consideration with LiveScope Plus is the GLS 10. Because the system requires an external sonar module, you're not simply finding space for a graph and transducer. The complete setup also needs room for the module, wiring, and a battery capable of powering everything.

That may not be a major concern in a permanently installed boat setup, but it becomes more important when you're building a portable system.

Garmin's newer LiveScope 2 changes that equation. LiveScope 2 connects directly to compatible Garmin chartplotters rather than requiring the separate GLS 10 black box used with LiveScope Plus. For anglers interested in portability, that's significant because eliminating an external module can reduce the amount of hardware and wiring that needs to be incorporated into the system.

The right Garmin setup therefore depends not only on whether you want LiveScope, but also on which generation of the system you're considering and which Garmin display you're planning to use.

Lowrance ActiveTarget

Lowrance's forward-facing sonar platform is ActiveTarget, with ActiveTarget 2 offering Forward, Down, and Scout viewing modes.

Forward and Down provide the more familiar directional sonar views, while Scout gives anglers a wider look ahead of the boat. Lowrance also allows ActiveTarget 2 systems to be expanded with additional hardware and a second transducer for certain simultaneous and wider-view configurations.

Like LiveScope Plus, ActiveTarget 2 uses a separate sonar module. That's worth remembering when you're comparing complete setups because the module needs to be mounted, wired, and powered along with the display and transducer.

ActiveTarget makes the most immediate sense for anglers who are already running compatible Lowrance displays such as HDS PRO, HDS LIVE, HDS Carbon, or Elite FS. If you're already comfortable with Lowrance electronics and have compatible equipment on the boat, staying within that ecosystem can simplify the decision.

Humminbird MEGA Live

Humminbird's MEGA Live platform brings forward-facing sonar into the Humminbird ecosystem.

As with Garmin and Lowrance, MEGA Live allows anglers to see fish and structure in real time and adjust the transducer orientation depending on the type of view they're trying to achieve.

Where MEGA Live can become especially appealing is for anglers who already have a boat built around Humminbird and Minn Kota equipment. Your forward-facing sonar isn't operating in isolation from the rest of your electronics, so existing graphs, networking, mapping, trolling motor integrations, and familiarity with the interface can all influence which system makes the most sense.

That's an important point in this entire comparison. Choosing forward-facing sonar based exclusively on which transducer produces your favorite screenshot can overlook a much bigger part of the decision.

The Electronics You Already Own Matter

Before comparing image quality, viewing modes, or individual specifications, we'd start with a simple question:

What electronics are already on your boat?

If you already own a compatible Garmin chartplotter, LiveScope may require fewer additional components than switching your entire setup to another brand. The same applies if you're already invested in Lowrance or Humminbird.

Switching forward-facing sonar brands can potentially mean buying more than a new transducer. Depending on your existing equipment, you may need another display, different networking components, mounting hardware, or other accessories.

That's why comparing only the price of each sonar system doesn't always tell you what it will actually cost to build the setup you want.

If you're starting completely from scratch, you have more freedom. In that case, we'd spend less time worrying about brand loyalty and more time considering the complete system you're going to end up with.

What About Image Quality?

This is probably the part of the comparison where anglers want us to pick a winner.

We're not going to.

Garmin, Lowrance, and Humminbird are all capable of providing useful real-time sonar images, and what you actually see on the screen depends on more than the name printed on the transducer.

Water conditions, depth, bottom composition, interference, transducer position, range, settings, and the operator's experience can all influence image quality. An angler who understands how to properly aim and tune a system may get considerably more useful information from it than someone who buys whichever sonar is currently considered the "best" but never learns how to use it.

The species you're targeting matters too. Someone scanning brush piles for crappie in 20 feet of water isn't necessarily looking for the same thing as an angler targeting lake trout in deep water or a bass angler following an individual fish.

If image quality is your biggest deciding factor, try to see the systems being used under conditions that resemble the way you actually fish. That will tell you much more than comparing carefully selected screenshots online.

Viewing Modes and How You Fish

All three platforms allow anglers to look ahead of the transducer, which is where many people spend most of their time with forward-facing sonar. This is the traditional experience of aiming toward a fish, brush pile, weed edge, rock, timber, or school of bait and casting toward what you see on the screen.

The differences become more noticeable when you look at the additional viewing options each manufacturer offers.

Garmin LiveScope Plus includes Forward, Down, and Perspective modes. Lowrance ActiveTarget 2 offers Forward, Down, and Scout modes, along with additional possibilities when more hardware is added. Humminbird offers its own viewing options within the MEGA Live platform.

There isn't necessarily one viewing mode that's universally more useful than another. Consider whether you spend more time targeting individual fish, searching larger areas, fishing vertically, or looking for structure. The way you use forward-facing sonar should influence which features matter to you.

Portability Changes the Comparison

If you're planning to make your forward-facing sonar portable, there are a few additional things to consider.

A portable sonar system isn't just a graph and transducer. Depending on the sonar you're using, the complete system can include the display, external sonar module, battery, wiring, shuttle, transducer pole, and other accessories.

All of those components need to work together.

That's especially noticeable for ice fishing, where you're physically carrying the entire system from one location to another. Size and weight that may be insignificant in a permanently installed boat setup suddenly become much more noticeable when you're pulling a sled and moving from hole to hole.

It's also one reason the removal of the external black box from Garmin LiveScope 2 is interesting from a portability standpoint. Fewer separate components can make it easier to build a compact system.

This is the same reason we recommend thinking about your shuttle, transducer pole, and battery while choosing your electronics rather than after you've already purchased everything.

Don't Overlook the Transducer Pole

Regardless of which sonar brand you choose, the system can only show you what the transducer is pointed toward.

For many forward-facing sonar setups, an independent transducer pole gives the angler direct control over where the sonar is looking rather than tying the view to the direction of the boat or trolling motor.

If you see a fish off to the side, you can turn the pole toward it. If you want to inspect a brush pile, you can aim directly at the structure. On the ice, the same concept lets you scan around the hole and then quickly pull the pole when it's time to move.

A stable, easy-to-control pole won't change the sonar technology itself, but it can have a significant effect on how easy that technology is to use.

Battery Size Should Match the Complete System

Power is another area where anglers sometimes focus on one component instead of the entire setup.

Your graph draws power, but depending on your sonar system, an external module may also be part of the electrical load. Screen size, brightness, accessories, temperature, and how long you plan to fish can all affect how much battery capacity makes sense.

A four-hour evening trip doesn't have the same requirements as a twelve-hour tournament day. Likewise, a compact portable setup doesn't necessarily benefit from installing the largest battery you can find if you don't need the additional capacity.

The goal should be enough power for your complete electronics system and typical fishing day while keeping the size and weight practical for the way you're going to use it.

So, Which Forward-Facing Sonar Should You Choose?

For someone already invested in one electronics ecosystem, we'd start there.

If you're running compatible Garmin electronics and like Garmin's interface and ecosystem, LiveScope is a natural system to consider. You'll also want to decide whether LiveScope Plus or the newer LiveScope 2 makes more sense for the setup you're building.

If your boat is already equipped with compatible Lowrance displays, ActiveTarget 2 gives you forward-facing sonar while keeping you within the Lowrance ecosystem, along with Forward, Down, and Scout viewing options.

If you're already using compatible Humminbird and Minn Kota equipment, MEGA Live may be the most logical way to add forward-facing sonar without moving away from the electronics ecosystem you've already built.

For anglers starting from scratch, we'd look at all three in person if possible. Pay attention to how easily you can interpret the image, whether the controls make sense to you, which viewing modes fit your fishing, what display you want to use, and what the entire system will cost and weigh once it's complete.

Those questions are much more useful than asking the internet which brand is best.

Build the System Around the Way You Fish

LiveScope, ActiveTarget, and MEGA Live can all give anglers a real-time look at what's happening beneath the surface. The better choice comes down to how that technology fits into the rest of your fishing.

Think about the electronics you already own, the species you target, whether you're fishing from a boat or on the ice, how portable you need the system to be, and how long you need it to run.

At Summit Fishing Equipment, that's also how we approach forward-facing sonar equipment. We don't think your electronics should dictate how you have to fish. The shuttle, transducer pole, mounting system, battery, and accessories should work together to make the sonar system easier to use.

Whether that's a permanent boat setup, a completely portable system, or something you move between open water and ice, build it around the way you actually fish.
