Most beginners do not need live sonar yet. For the ones who do, here are the four systems that make sense as a first one, and the regular fish finder to learn on instead.
Short answer: most beginners do not, at least not yet. Forward-facing sonar shows a live, moving picture of the water in front of the boat, so you can watch a fish turn toward your bait. It is impressive. It also costs several times what a good first fish finder does, it needs a boat that can hold position (usually with a trolling motor), and it assumes you already know what depth, bottom and cover look like on a normal screen. Two Bassmaster columns make the same call: Greg Hackney's is titled "You don't need forward-facing sonar," and Stetson Blaylock argues that bass basics should come before it.
So who should buy one? Someone who already fishes from a boat with a trolling motor, can read 2D and down imaging, and keeps losing fish that suspend off the bottom where a down-looking unit never sees them. Crappie and open-water bass anglers feel that gap first. If that is you, the real decision is less about brand and more about the screen you already own, because three of the four live sonar picks below only work with a compatible display from the same maker.
The ranking reflects that. The Lowrance Eagle Eye 9 Live comes first because it is the only open-water pick that puts the live sonar transducer and the screen in one box. The Humminbird and Lowrance add-on transducers come next for anglers who already run one of those makers' compatible units. Garmin's complete ice bundle is the pick for hard water. Last is the Garmin Striker Vivid 7cv, which is not live sonar at all: it is the screen to learn on first. Ratings and review counts are from Amazon buyers, specs are from each maker or its listing, and Tom has not tested these units.
The transducer is the famous part. These are the other pieces that decide whether a live sonar system actually works on your boat, and the first two are where most first purchases go wrong.
Each maker's transducer talks only to that maker's compatible screens. Check your exact model against the list before buying. The Eagle Eye 9 Live and Garmin's ice bundle include their screens.
Garmin says LiveScope needs a GLS 10 sonar box. ActiveTarget 2 ships with its module in the box. Humminbird MEGA Live 2 and the Eagle Eye 9 Live need no separate module.
Usually the trolling motor shaft, so the transducer turns where the motor points. A dedicated live sonar pole or a transom adapter are the alternatives, and on the ice it is a pole mount in the hole.
Live sonar needs its own power feed from the boat's battery. MEGA Live 2 comes with a 10 foot power cable and a 20 foot Ethernet cable, per Humminbird. Plan the cable run from the bow to the screen before you mount anything.
Not part of live sonar, but the screen it runs on usually adds charts and waypoints. The Eagle Eye 9 Live's listing includes C-MAP charts covering more than 17,000 US lakes.
Advanced setups run two transducers for wider coverage. Lowrance's listing says ActiveTarget 2's 180 degree and Scout Wide views need a second transducer, and its multi-view features need an HDS PRO. Not a first-season purchase.
Live sonar is sold three ways, and which one fits depends almost entirely on what is already on your boat.
A display and a live sonar transducer sold together. The Eagle Eye 9 Live is the open-water example on this page and Garmin's ice bundle is the hard-water one. Nothing else to match.
MEGA Live 2 and ActiveTarget 2 add live sonar to a Humminbird or Lowrance display you already run. The cheapest route if your screen is on the list, and a dead end if it is not.
A CHIRP and down imaging unit with GPS. It will not show fish moving in real time, but it teaches every skill live sonar depends on, at a fraction of the cost.

Live sonar transducers are not universal. Humminbird lists MEGA Live 2 as compatible with XPLORE, APEX and SOLIX G3 units, and says the unit must be a MEGA Side Imaging or MEGA Down Imaging model. Lowrance's ActiveTarget 2 needs a compatible Lowrance display such as HDS PRO, HDS LIVE or Elite FS (per dealer listings). Garmin says a GLS 10 sonar box is required for LiveScope, on top of a compatible GPSMAP or ECHOMAP. If you own none of these, the Eagle Eye 9 Live is the only open-water pick here that needs nothing else.
An add-on transducer is the start of the bill, not the end. A first-time buyer may also need the compatible display, a mount for the trolling motor or a pole, and power wiring. Garmin's ice bundle includes the chartplotter, the transducer, the GLS 10 box, a pole mount and a lithium battery with charger, which is why it sits in a higher price band than everything else here.
Forward-facing sonar has to be aimed, which is why it usually rides on the trolling motor shaft and turns with it. Humminbird's page names Minn Kota Ultrex, Fortrex, Maxxum and Edge motors for MEGA Live 2, says most live sonar poles work, and sells a separate adapter for transom mounting. On the ice, the transducer goes on a pole you turn by hand in the hole.
Every live sonar system here does a forward view and a down view. Humminbird adds Landscape, Lowrance adds Scout, and Garmin adds Perspective, which are all ways of looking out to the sides for fish spread over flats. Lowrance's listing says multiple simultaneous views on ActiveTarget 2 need an HDS PRO display. For a first system, forward and down are the two you will use most.
The Eagle Eye 9 Live connects its transducer straight to its own 9 inch screen with no separate sonar module, per Lowrance's listing. It is the shortest path from nothing to live sonar on open water.
Check the model on your bow before buying. MEGA Live 2 plugs into XPLORE, APEX and SOLIX G3 units over Ethernet with no black box. ActiveTarget 2 ships with its own module and needs an HDS or Elite FS class display.
Spend a season on a standard unit with down imaging and GPS. The Striker Vivid 7cv teaches depth, bottom and arches, and everything you learn carries straight over when you add live sonar later.
Live sonar has a learning curve of its own, even for anglers who read a regular screen well. This is a sensible order to learn it in.
Point the transducer straight down and compare it with your regular sonar. It is the easiest way to learn how fish, bait and brush look on a live screen.
Aim it ahead over a spot you already know, like a brush pile or a dock. Seeing structure you recognise teaches you the scale of the screen.
Use the trolling motor to keep the beam on one area. A drifting boat makes fish appear and vanish, which is easy to misread as fish moving.
Put the lure just past and above a fish, then watch it react. Note what it ignored as well as what it ate.
Fish a few hours a trip without it. The basics it builds on, reading cover and depth, still catch most fish.
Once you know which kit type fits your situation, dig into each gear category for in-depth picks and buying advice:

Mostly no. It is expensive, it needs a boat that can hold position and a compatible screen, and it skips the basics it depends on. Greg Hackney's Bassmaster column is titled "You don't need forward-facing sonar," and Stetson Blaylock's argues that bass basics should come first. Learn depth, structure and fish arches on a regular unit, then add live sonar once you know what you are looking at.
Sonar that shows a live, constantly refreshing picture of the water in front of the boat instead of a scrolling history of what is under it. Fish, bait and your lure show up as moving shapes, so you can cast to a fish you can see and watch how it reacts. Garmin calls its version LiveScope, Lowrance calls its ActiveTarget, and Humminbird calls its MEGA Live.
Only if it is on the maker's compatibility list. Humminbird lists MEGA Live 2 for XPLORE, APEX and SOLIX G3 units with MEGA Side or Down Imaging, so Helix and PiranhaMAX units are not on it. ActiveTarget 2 works with Lowrance displays such as HDS PRO, HDS LIVE and Elite FS, according to dealer listings. Garmin LiveScope needs a GLS 10 sonar box and a compatible GPSMAP or ECHOMAP. Garmin's LiveScope Plus list names GPSMAP and ECHOMAP families, not the Striker line.
Not strictly, but it works best with one. The transducer has to be aimed, so it usually mounts on the trolling motor shaft and turns with it. Humminbird also supports most live sonar poles and sells a transom adapter for MEGA Live 2. On the ice you mount it on a pole in the hole, which is what Garmin's ice bundle includes.
It depends on the system and the water. Garmin's ice bundle listing says LiveScope Plus can see up to 200 feet in any direction, and Garmin's launch release says it can separate targets as small as 14 inches at 100 feet from the boat. Humminbird publishes MEGA Live 2's coverage as a 20 by 120 degree beam rather than a distance. Garmin's LiveScope XR is the long-range model, at up to 500 feet in freshwater by Garmin's figure.
It can be, if you already ice fish a lot. Garmin's listing describes the two uses: Forward mode to scout schools of fish before you drill the next hole, and Down mode to watch your jig and see fish react to it. For a first season on the ice, a flasher does the down job for far less money.
A standard fish finder with CHIRP sonar, down imaging and GPS. It reads depth and bottom, draws cover clearly, and lets you mark the spots where you catch fish. The Garmin Striker Vivid 7cv on this page does all three on a 7 inch screen, and our beginner fish finder guide ranks smaller and cheaper options.
