I went to godfrey point on oneida lake, New York yesterday to take a look around. The water was wide open and there was 2 guys casting off the end of the point. I chuckled to myself seeing a huge top water lure being casted.
As I approached, I saw no hooks on it. They showed me the coolest thing I have seen in years. It was a castable transducer with a hand held screen. The transducer must have a transmitter to send a signal telling what is going on.
The transducer was like 2 1/2 " around and they explained that a line could be tied on the back side and a lure could be seen on the transducer.
I hope they don't tie on to a big tiger muskey and lose that rig.
