I bought me a hummingbird 565 about a month ago. It is detachable from the mount, like most all fish finders are. Before installing, I tested the connection of the detachable power and transducer cable to the head and thought to myself, the power cable seems to kinda fit loose. I installed and sure enough, every time I hit a wake, wave or any little thing that jolts the boat, the unit looses power and turns off. This is a major pain. I'm sure hummingbird will gladly send me a new cable, but hate to even have to mess with it again. I figured hummingbird was a quality product, they've been around a while. Anyone have the same problem with this type fish finder?
