Bought one of them big Ole clumsy flashy gadgets myself. Can't remember the exact date but was in the seventies.
I believe the price was $99.99 and I bought it at Fergies on Wilhelm. Mounted the thing on my 16ft Starcraft SS.
Like today, back then, I knew nothing about the operation but like today, back then, I sure did look good.
I think mine can be found in a landfill somewhere in Ohio. However, Fergies is certainly still working. Though under new ownership, some years back.
Kokanee thanks for mentioning the Lowranger Flasher. Many many great memories.
