Raymarine Fish Finders

Raymarine is a company with a long and rich history in the fish finder category. They produced their first depth sounder way back in 1923, and have expanded into several other niches in subsequent years. Currently, Raymarine is more of a global marine electronics maker, manufacturing everything from fish finders to marine radar to autopilot systems.
Most of their mid- and high-end products include GPS capabilities, and their down-imaging sonar technology (DownVision) is included with even their entry-level units.
