CHIRP technology: better target separation and a sharper image than classic 2D sonar.
DownScan / SideScan: near-photographic view below and around the boat — great for finding structure.
GPS and mapping: mark spots, follow tracks, build depth maps.
Screen size and resolution: bigger is easier to read, especially in bright sun.
Transducer: transom mount for boats, or a float/portable unit for ice fishing and kayaks.
Use and budget: an entry model is fine to start; aim for CHIRP + GPS if you fish often.
Garmin Striker Vivid
The best value for getting started. Traditional CHIRP sonar plus built-in GPS (mark spots and trails) with a color screen that stays readable in bright sun. Downside: no detailed mapping on the smaller models. For whom: a first all-around finder, from kayak to jon boat.

A step up. Detailed mapping and a touchscreen, with LiveScope (real-time sonar) compatibility on the UHD/UHD2 versions. Downside: pricier, and you often have to add the LiveScope transducer. For whom: the serious angler who wants to read structure and watch fish live.
View on Amazon ↗Lowrance HOOK Reveal
Simple and reliable. DownScan Imaging for a clean bottom picture plus base mapping, with little to fiddle with. Downside: fewer advanced options than the Elite line. For whom: anyone who wants an effective finder without the hassle.
View on Amazon ↗Lowrance Elite FS
Accessible high-end. Active Imaging 3-in-1 (DownScan + SideScan), ActiveTarget (real-time) compatibility and networking. Downside: reaching its full potential takes extra accessories. For whom: the advanced angler who wants fine imaging without going all the way to the top tier.
View on Amazon ↗Humminbird HELIX
Known for sharp imaging (MEGA Imaging Down/Side) and solid mapping. A wide range (small to large screens) to match your budget and boat. Downside: the interface can feel less intuitive than Garmin. For whom: those who put image quality first.
View on Amazon ↗Humminbird PIRANHAMAX
The entry level for getting started without spending much. A simple 2D display of the bottom, fish and depth. Downside: no GPS or mapping. For whom: a small budget, a jon boat or a backup — enough to understand what is under the boat.
