Three years ago, forward-facing sonar was a Garmin exclusive and LiveScope was a $3,000 novelty item on elite tournament boats. Today, three major manufacturers have mature, competitive forward sonar platforms — and the gap between them has narrowed substantially.
This comparison focuses entirely on helping you make the right call for your specific setup, budget, and fishery. If you’ve already decided on live sonar and just need to buy, jump to the full live sonar collection at Pro Marine Electronics.
The Three Contenders — System Overview
Garmin LiveScope Plus (LVS34 / GLS10)
Garmin’s second-generation live sonar system. The LVS34 transducer replaced the original LVS32 in 2022 with meaningful improvements in shallow-water clarity and stained-water performance. Three modes: Forward, Down, and Perspective (exclusive to Plus). MSRP: ~$1,799–$2,099. Ecosystem: Garmin-only displays.
Lowrance ActiveTarget 2
Lowrance’s second-generation live sonar with redesigned LSS-2T transducer that produces noticeably sharper target separation. Scout mode (shallow) and Live mode (deeper water) plus dual-transducer support on HDS PRO. MSRP: ~$1,699–$1,999. Ecosystem: Lowrance HDS PRO / HDS Live only.
Humminbird MEGA Live Imaging
Built into MEGA frequency-capable HELIX and SOLIX units at 1.2 MHz. Offers Forward, Down, and 360° (with MEGA 360 — sold separately). The 360 integration is MEGA Live’s most unique capability. MSRP: ~$1,499–$1,999. Ecosystem: Humminbird HELIX/SOLIX MEGA displays.
Head-to-Head Specification Comparison
| Spec | LiveScope Plus (LVS34) | ActiveTarget 2 (LSS-2T) | MEGA Live |
|---|---|---|---|
| Frequency | ~1.05 MHz | ~1.08 MHz | 1.2 MHz |
| Max Forward Range | 200 ft | 200 ft | 175 ft |
| Frame Rate | Up to 30 fps | Up to 30 fps | Up to 30 fps |
| Dual Transducer Support | No | Yes (HDS PRO) | Limited |
| Unique Mode | Perspective | Scout + Live modes | MEGA 360 integration |
| Price | ~$1,799 | ~$1,699 | ~$1,499 |
Image Quality and Real-World Performance
LiveScope Plus — The Reference Standard
LiveScope Plus remains the benchmark image: Garmin’s processing algorithm is more mature than competitors, having gone through two full hardware generations and dozens of firmware iterations. The live image is smoother with better fish/structure discrimination at 50–100 ft. Perspective Mode is genuinely useful for dock fields, bridge pilings, and riprap banks.
ActiveTarget 2 — Best Shallow/Stained Performance
ActiveTarget 2’s Scout mode produces the clearest shallow-water image of the three systems in the 3–15 ft range. If your fisheries are tannic southeastern reservoirs (Santee, Seminole, Okeechobee), ActiveTarget 2 wins outright. The dual-transducer capability on HDS PRO lets you run Scout forward and Down simultaneously — no other platform offers this.
MEGA Live — Best Ecosystem Integration
MEGA Live’s differentiator is MEGA 360 integration. A MEGA 360 Imaging transducer adds a real-time 360° rotating sonar view alongside your forward view — no competitor offers this. The Humminbird/Minn Kota i-Pilot Link ecosystem integration is also the tightest hardware pairing of the three systems.
Decision Matrix
| If you are… | Buy… |
|---|---|
| Already a Garmin chartplotter user | LiveScope Plus LVS34 |
| Fishing stained/shallow water primarily | ActiveTarget 2 |
| Running a Humminbird/Minn Kota integrated setup | MEGA Live |
| Wanting two sonar perspectives simultaneously | ActiveTarget 2 (HDS PRO dual-transducer) |
| Wanting 360° live sonar capability | MEGA Live + MEGA 360 |
| Starting a new build from scratch | LiveScope Plus + ECHOMAP Ultra 2 |
Final Verdict
LiveScope Plus leads at medium to long range. ActiveTarget 2 wins shallow/stained water and is the only system with dual-transducer live view. MEGA Live wins on ecosystem integration — specifically i-Pilot Link pairing and the unique MEGA 360 option.
