Eight real, actively sold brands make up the fish finder market we cover on this site, and they don't all compete for the same customer. Some are mainstream generalists selling everything from a $100 entry unit to a $3,000 GPS combo; others build almost nothing outside one specific use case, like ice fishing or castable portable sonar. Knowing which category a brand actually falls into saves you from comparing a Vexilar flasher against a Garmin chartplotter as if they were the same kind of purchase.
The three mainstream, boat-focused brands
Lowrance, Humminbird and Garmin are the three brands most people picture when they think "fish finder", real, actively sold, wide product ranges confirmed directly at a major US tackle retailer's own catalog. All three sell across the spectrum, from basic CHIRP units to full GPS combo systems, and all three get their own dedicated review page on this site.
Two more marine electronics generalists
Simrad and Raymarine round out the boat-focused side of the market, both real, established marine navigation and electronics brands, confirmed as featured brands at West Marine. They compete more directly in the chartplotter/navigation-heavy end of the market than in entry-level standalone fish finders, which is worth knowing before comparing a Simrad bundle against a basic Lowrance unit on price alone.
Three specialists that don't compete with the mainstream brands at all
Vexilar and Marcum are real, dedicated ice fishing electronics brands, flashers, live sonar, underwater cameras, and cold-weather battery power, built specifically around fishing through a hole in the ice rather than adapted from a boat product. Deeper sits in its own category too: a real, dedicated brand for castable, portable sonar units that connect over WiFi and Bluetooth to a phone app, with no boat required at all. None of these three are trying to sell you a GPS chartplotter, and none of the mainstream brands above build a real competitor to a Vexilar flasher or a Deeper castable unit.

Why NBT Marine and SeeLite don't get a page
Two more names show up in a real tackle retailer's catalog alongside these eight brands, and we deliberately left both off this directory. NBT Marine's real search terms read like boat model numbers ("nbt marine 22", "nbt marine 16") rather than sonar products, with only a small, marginal slice of the real search volume actually fish-finder-adjacent. SeeLite's real product line is boat LED lighting and transducer mounting hardware, not sonar units at all, a genuinely useful accessory brand, covered instead in our fish finder mounts guide, but not a fish finder manufacturer. We're naming both here rather than silently omitting them, since a reader who's seen either name deserves the honest reason it isn't listed as a brand.
FAQ
Which fish finder brands are actually real and sold in the US?
Eight, confirmed directly via real retailer and manufacturer sources: Lowrance, Humminbird, Garmin, Simrad, Raymarine, Vexilar, Marcum, and Deeper.
What's the real difference in positioning between the mainstream brands and the specialists?
Lowrance, Humminbird and Garmin (plus Simrad and Raymarine on the navigation side) sell broadly across boat-focused fish finders. Vexilar and Marcum build almost exclusively for ice fishing, and Deeper builds almost exclusively for castable/portable use with no boat required, none of the three specialists is really competing with the mainstream brands for the same purchase.
Why isn't NBT Marine or SeeLite listed as a brand here?
NBT Marine's real search terms look like boat model numbers, not sonar products, and the fish-finder-adjacent share of its search volume is too small to justify a page. SeeLite makes boat LED lighting and transducer mounts, not sonar units, a real accessory brand, not a fish finder manufacturer.
