Lowrance Transducer Overview

Main Transducer Lines
ActiveTarget 2 / ActiveTarget 2 XL (Live Sonar)
ActiveTarget 2 gives you the highest resolution and clearest live views of fish and structure, letting you watch fish respond to your lure in real time. Lowrance The newest XL version takes it further — it offers surface-to-surface 180-degree views across Forward, Down, and Scout modes from a single transducer, starting at $1,399. Boating Mag
Active Imaging HD / 3-in-1
The Active Imaging 3-in-1 is currently the most popular Lowrance transducer, typically included with new HDS Live and Elite FS units. It combines 2D/CHIRP, SideScan, and DownScan in one transducer. Sportfishing Buddy
StructureScan 3D
Provides a real-world, three-dimensional view of fish, structure, and bottom contour, making it easier to know where fish are located in relation to your boat. Lowrance
TripleShot (for HOOK2/HOOK Reveal series)
The TripleShot supports High CHIRP at 200kHz along with SideScan and DownScan at 455/800kHz, and its wide-angle CHIRP offers double the sonar coverage compared to most fish finders. The Idaho Fisherman
HDI Skimmer
The HDI Skimmer is a more advanced transducer with both 2D and DownScan imaging and CHIRP capability, including 455 and 800kHz frequencies for more resolution and detail. Sportfishing Buddy

Frequencies Explained
Here’s what the key frequencies mean: 50kHz (Low CHIRP) — lower frequency, higher power for deep-water fishing. 83kHz (Medium CHIRP) — widest coverage area, ideal for shallow water. 200kHz (High CHIRP) — higher resolution, better for discerning fish from structure. 455kHz — large range scanning with high resolution. 800kHz — less range but the highest resolution detail.

Choosing the Right Transducer
Four key questions to ask: What sonar type do you need? What depth/frequency range suits your fishing? What mounting style fits your boat (transom, trolling motor, or thru-hull)? And is the transducer compatible with your specific Lowrance display unit? Sportfishing Buddy
The main points Lowrance recommends considering are: how it will be mounted, what views you want, and what frequencies you need. Lowrance
