Humminbird MEGA Live 2 review: check compatibility before you buy anything else
Quick answer
Humminbird MEGA Live 2 is a $1,284.02 forward facing live sonar system compatible only with XPLORE, APEX and SOLIX G3 control heads. It is not a Helix accessory and it is not compatible with any Garmin display, which makes checking your existing screen the single most important step before ordering.
MEGA Live 2 is Humminbird's forward facing live sonar system, the category that lets an angler watch a lure fall and fish react to it in real time instead of reading a static picture of what already passed under the boat. It is the most expensive single upgrade covered on this page, and the single most useful fact about it has nothing to do with picture quality.
That fact is compatibility. This review is built from Humminbird's published specification sheet, including its own stated compatible equipment list, and the recurring themes in verified owner reviews, not from running the unit ourselves. Read the compatibility section before the rest of this page, because it decides whether anything else here applies to you at all.

Which screens actually work with MEGA Live 2
Humminbird publishes MEGA Live 2 as compatible with its XPLORE, APEX and SOLIX G3 control heads, connecting directly to the head over an included Ethernet cable with no separate sonar box required. It is not compatible with the Helix line at all, including the flagship Helix 7 MEGA SI GPS G4N, and it is not compatible with any Garmin display under any circumstances. This is the single most common source of a returned or wasted purchase in this category, and it is worth repeating plainly: if your boat runs a Helix or a Garmin screen, this specific product will not work on it no matter what accessory you add.
What the system does once it is running
On a compatible head, MEGA Live 2 publishes Forward, Down and Landscape viewing modes, along with dynamic bait and lure tracking and an optimized cone angle intended to balance individual fish targeting against broad coverage. The complete installation kit includes an adjustable mounting bracket sized to fit either side of a trolling motor shaft, a 10 foot power cable and a 20 foot Ethernet cable, along with the mounting hardware.
Based on published specifications and the recurring themes in verified owner reviews, most feedback centers on how quickly forward facing sonar changes fishing habits once an angler has used it for a season, less on the mechanics of installation, which owners describe as straightforward with the included bracket and cables.
Live sonar systems compared on paper
Forward facing sonar is not a one brand category, and the compatible head requirement changes which system is even an option for a given boat.
MEGA Live 2 costs $1,284.02 and needs a compatible XPLORE, APEX or SOLIX G3 head, while the Lowrance Eagle Eye 9 bundles the display and live sonar together for $999.00.
Published figure A published engineering, regulatory or manufacturer figure. It does not change because somebody disagrees with it.
| System | Compatible heads | Price |
|---|---|---|
| Humminbird MEGA Live 2 | XPLORE, APEX, SOLIX G3 only | $1,284.02 |
| Garmin LiveScope Plus System | Compatible Garmin ECHOMAP or GPSMAP, head sold separately | $1,445.00 |
| Lowrance Eagle Eye 9 | Self-contained, no separate head needed | $999.00 |
Each price and compatibility statement is the maker own published listing at the time this table was built.
What is wrong with the MEGA Live 2 compatibility list
The narrow compatibility list is the real limitation, not the sonar performance. Locking a purchase to XPLORE, APEX and SOLIX G3 heads means an owner of any other Humminbird screen, including a brand new Helix, cannot use this specific product at all, and there is no adapter or workaround published by Humminbird that changes that. A buyer who already owns a compatible head gets a genuinely capable system. A buyer who does not is looking at replacing the head first, which turns a roughly $1,284 purchase into a multi thousand dollar one.
The second cost to plan for is a dedicated power source. Forward facing sonar draws enough current that most installations run it from its own battery or a dedicated circuit rather than sharing power with the rest of the electronics, and Humminbird does not publish an amp draw figure for MEGA Live 2 on its own listing.
Comparing MEGA Live 2 against the complete Lowrance package
| Specification | Humminbird MEGA Live 2 forward facing sonar | Garmin LiveScope Plus System with GLS 10 and LVS34 | Lowrance Eagle Eye 9 Live Sonar |
|---|---|---|---|
| Price | $1,284.02 | $1,445.00 | $999.00 |
| Transducer included | not published | LVS34 | not published |
| Sonar module | not published | GLS 10 | not published |
Every figure above is the manufacturer own published specification. Where a maker does not publish a figure the cell reads "not published" rather than carrying an estimate, because on ratings and currents an estimate that reads as a specification is a safety problem rather than a gap.
Alternatives if your screen is not on the MEGA Live 2 list
If your boat already runs a compatible Garmin ECHOMAP or GPSMAP, the Garmin LiveScope Plus System is the equivalent purchase built for that ecosystem instead. If you do not already own a compatible head from either brand and do not want to buy one just to add live sonar, the Lowrance Eagle Eye 9 bundles a nine inch display and live forward and down sonar into one purchase with no separate head required, and it is the cheapest complete entry point into this category covered on this site.
How we chose
We did not test this equipment in person and we never claim to. Picks are researched from manufacturer specification sheets, published engineering and regulatory figures, and the recurring themes in verified owner reviews. Every pick is matched to a real thrust rating, a real published amp draw, a real capacity or a real conductor size rather than to a price bracket, and it is placed in the tier where its published capability actually belongs. We rejected the unbranded flood that dominates several of these search results, because a lithium pack whose management board is the only thing between a cell fault and a fire, a breaker protecting a battery cable, a life jacket and a bracket holding a two thousand dollar motor to the bow at highway speed are all parts whose failure has a consequence nobody can walk away from. Where a figure is convention rather than a published standard we label it that way, and where a manufacturer does not publish a figure we leave it out instead of estimating it.

Frequently asked questions
Will MEGA Live 2 work with my Humminbird Helix?
No. Humminbird publishes MEGA Live 2 as compatible with its XPLORE, APEX and SOLIX G3 control heads only, and the Helix line is not on that list under any model or generation, including the newest MEGA SI G4N. If your boat runs a Helix head and you want forward facing live sonar, you need to replace the control head with a compatible one before this product becomes usable at all.
Does MEGA Live 2 work with Garmin displays?
No, and this is worth stating plainly because it is the most common mistake buyers make in this category. MEGA Live 2 is a Humminbird product built for Humminbird's own XPLORE, APEX and SOLIX G3 heads, and it has no compatibility with any Garmin ECHOMAP, GPSMAP or Striker display. A Garmin owner who wants forward facing sonar should look at the Garmin LiveScope Plus System instead.
How is MEGA Live 2 installed on the boat?
The complete kit includes an adjustable mounting bracket sized to fit either side of a trolling motor shaft, a 10 foot power cable and a 20 foot Ethernet cable that connects directly to a compatible control head with no separate sonar box in between. Owners consistently describe the physical mounting and cabling as straightforward, since the bracket is purpose built for a trolling motor shaft rather than requiring a custom mount.
Does MEGA Live 2 need its own battery?
Humminbird does not publish a specific current draw figure for MEGA Live 2 on its own listing, but forward facing sonar systems in general draw enough power that most installers run them from a dedicated battery or circuit rather than sharing power with the rest of the boat electronics. Plan the electrical side of the installation before mounting day, not after.
What is the difference between MEGA Live 2 and MEGA 360?
MEGA Live 2 shows a live forward, down or landscape view of what is directly ahead of or beneath the boat, which is built for watching a lure and a fish react to it in real time. MEGA 360 instead sweeps a full circle around the boat to answer what is around the boat generally, rather than what is happening to one specific lure. They solve different questions and many serious anglers eventually run both.
Is MEGA Live 2 worth the price if I already own a compatible head?
If your boat already runs a compatible XPLORE, APEX or SOLIX G3 head, the roughly $1,284 cost is in line with the rest of the forward facing sonar category, and owner feedback consistently describes it as changing how people fish once they have used it for a season. The value case falls apart quickly if you have to buy a new control head first just to use it.

Researched, not professional advice. This page is compiled from published engineering and regulatory figures, manufacturer specifications and owner-review consensus, not hands-on testing. Figures described as a rule of thumb are boating convention rather than published standards, and they are labelled that way wherever they appear. Marine electrical work is not house wiring. Use tinned, finely stranded marine cable, size it for voltage drop and for the ABYC E-11 ampacity table rather than one or the other, and put overcurrent protection within seven inches of the battery positive terminal, because everything between the post and the fuse is unprotected. A lithium battery needs a charger with a lithium profile. Never load a boat past its capacity plate, and remember that canoes and kayaks carry no federal capacity plate at all, so their stated capacity is the manufacturer own figure. Wear the life jacket, and treat early season water as the hazard it is: cold water immersion takes your breath and then your hands long before it takes your core.
