MEGA Live 1 vs MEGA Live 2: Which Transducer Do You Have?

MEGA Live 1 and MEGA Live 2 sound almost identical when you see them in a product selector. They are not the same transducer, and choosing the wrong option gives you the wrong settings guide.

The dependable way to tell them apart is the item number on the transducer identification label. Housing shape, dimensions, and fishfinder compatibility can cross-check the answer. A box, receipt, or registration record may show a separate system or package number instead of the transducer number.

Quick answer

710304-1 on the transducer label means you have MEGA Live 1.
710310-1 on the transducer label means you have MEGA Live 2.
If it is working with a HELIX, it is MEGA Live 1. MEGA Live 2 does not work with HELIX.
An exposed ridged circular feature on the broad face is the easiest visual clue for MEGA Live 2.

On a phone, swipe the chart left or right to see every column.

Identification check	MEGA Live 1	MEGA Live 2
Humminbird item number	710304-1	710310-1
Product name	MEGA Live Imaging, first generation	MEGA Live 2 Forward-Facing Sonar
Housing clue	Taller, faceted housing with a smooth molded circular side area	More square housing with an exposed ridged circular feature on the broad face
Approximate size clue	One retailer lists 6 x 6 x 4 inches, without defining the measurement boundary	Amazon lists 5.41 x 5.45 x 1.88 inches as Product Dimensions, without defining the measurement boundary
HELIX compatibility	Yes, on specified networked MEGA Side Imaging or MEGA Down Imaging models	No
SOLIX compatibility	All SOLIX generations	SOLIX G3 only, with required software
APEX and XPLORE	Compatible	Compatible, with the required software on APEX
Fish Finder Coach option	Humminbird MEGA Live 1	Humminbird MEGA Live 2

Dimension note: Humminbird does not publish a directly comparable external housing measurement for both generations. The cited retailer values do not say exactly what points were measured. Use size only as a supporting clue.

Pictures of MEGA Live 1 and MEGA Live 2

First-generation Humminbird MEGA Live 1 transducer with smooth molded circular side area — **MEGA Live 1, item 710304-1.** Look for the smooth molded circular side area and the taller, faceted housing. Official Humminbird product image.

Humminbird MEGA Live 2 transducer with exposed ridged circular feature on broad face — **MEGA Live 2, item 710310-1.** The exposed ridged circular feature on the broad face is the quickest visual difference. Official Humminbird product image.

Compare the housing, not the mount angle. The mount can rotate into different viewing positions, so two pictures of the same generation can show the transducer at different angles.

TargetLock does not identify the generation by itself either. Humminbird says MEGA Live 2 works with new and existing TargetLock systems when TargetLock is running software 1.180 or later. Adapter 740251-1 is required only for existing TargetLock pole systems with a serial number below 250109010001. Check the transducer item number.

Where to Find the Item Number

Start with the transducer itself, then use the paperwork as a cross-check:

Inspect the identification label on the transducer cable.
Check a standalone-transducer box or receipt for 710304-1 or 710310-1.
Check the dealer receipt, online order history, or Humminbird registration record, but remember that a complete TargetLock or hand-control package can have its own number.
Use the pictures and compatible-unit chart below as a cross-check.

Do not use an accessory, bracket, or system-package number as the transducer number. For example, first-generation TargetLock and hand-control packages can show 710308-1 or 710309-1 even though the transducer itself is MEGA Live 1. Mounts and ice-fishing adapters have their own item numbers too.

If you are identifying other Humminbird sonar hardware on the same boat, use the broader Humminbird transducer identification guide.

Compatible Humminbird Fishfinders

Compatibility is useful when the label is missing, especially if the system is already working on the boat.

Fishfinder family	MEGA Live 1	MEGA Live 2
XPLORE	All models	All models
APEX	All models	All models with software 5.060 or later
SOLIX	All models	G3 only, with software 5.060 or later
HELIX G3N	8 through 12, MEGA Side Imaging or MEGA Down Imaging models	Not compatible
HELIX G4N	7 through 15, MEGA Side Imaging or MEGA Down Imaging models	Not compatible

HELIX installations also require the Humminbird AS EC QDE Ethernet adapter for MEGA Live connectivity. The fishfinder model is still a cross-check, not final proof. A previous owner may have replaced a control head or moved the transducer from another boat.

Which Option Should You Choose in the Fish Finder Coach Bundles?

Once you know the item number, the selector is simple.

Forward Facing Sonar Bundle

In the Forward Facing Sonar Bundle, open FFS Transducer and choose:

Humminbird MEGA Live 1 for item 710304-1
Humminbird MEGA Live 2 for item 710310-1

This is the primary bundle when you need the forward-facing sonar course and the matching MEGA Live settings guide.

Full Boat Bundle

If you also run a separate side-imaging or down-imaging transducer, use the Full Boat Bundle. Under FFS Live Sonar Transducer, choose the same matching option:

Humminbird MEGA Live 1 for item 710304-1
Humminbird MEGA Live 2 for item 710310-1

The dialed-in numbers for your forward-facing sonar are inside the Forward Facing Sonar Bundle. If you also run side imaging or down imaging, the Full Boat Bundle adds those settings and courses in the same package.

Frequently Asked Questions

What is the part number for MEGA Live 1?

The U.S. Humminbird item number for the first-generation MEGA Live Imaging transducer is 710304-1.

What is the part number for MEGA Live 2?

The Humminbird item number for MEGA Live 2 Forward-Facing Sonar is 710310-1.

Does MEGA Live 2 work with a HELIX?

No. Humminbird states that MEGA Live 2 is not compatible with any HELIX model. A working HELIX and MEGA Live installation uses the first-generation MEGA Live transducer, assuming the HELIX model and Ethernet connection meet Humminbird's requirements.

Does MEGA Live 2 work with SOLIX?

MEGA Live 2 works with SOLIX G3 models running software 5.060 or later. It does not work with SOLIX G1 or G2.

Can MEGA Live 1 work with an XPLORE?

Yes. Humminbird lists all XPLORE models as compatible with MEGA Live 1.

Can I identify my transducer by size alone?

No. Published dimensions may refer to the housing, mounted assembly, or retail package. Use the item number first and the dimensions as a cross-check.

Which bundle option do I select if I have TargetLock?

Choose by the transducer item number, not by the TargetLock name. Select Humminbird MEGA Live 1 for 710304-1 or Humminbird MEGA Live 2 for 710310-1. MEGA Live 2 also requires TargetLock software 1.180 or later, and older TargetLock pole systems below serial number 250109010001 require adapter 740251-1.
