In 1957, Lowrance invented The Little Green Box, the first ever sonar device for consumer-level users. Ever since then, they have been producing award-winning marine electronics to keep boats safer and more productive. Commercial fishermen, charter boat captains and weekend warriors the world over trust Lowrance navigation systems and fish finders. The HOOK line of fishfinder/chartplotter combos contain both sonar technology and DownScan imaging, producing a complete view of the underwater environment so you can see what baitfish, gamefish and structures are beneath your boat. If you're a winter angler, use a portable ice transducer to get the same view even when a layer of ice is in the way.
