Vexilar is Japanese......
The company is based in Shakopee Minnesota, but the units are built overseas. Same with Aqua-VU, based in Brainerd Minnesota but their product is built somewhere else.
As far as I know, Vexilar is/was Hondex. I remember seeing Dave Genz in an old magazine fishing with an FL-8 Hondex mounted in one of his homemade "Iceboxes". His unit was complete with a motorcycle battery and a compartment to secure it. In hindsight, I see a Vexilar FL-8 Genz Pack. He also had the prototype Fishtrap with him that was constructed of plywood and white canvas.
