electric troller "jig" machines ????????

[Litchfield Fisher]

has any one else heard of a small box that is electonic and has a spot where you mount a rod holder to it hook it to a battery and then after turned on it pulls your rod up along the boat and then drops in back down to give that flashy jitter movment of the bait in the water to add attraction to it as I have for years often pumped trolling rods occasionly but never heard of one of these has any one else used them and if so are they worth the money I just heard about them when reading a newhampshire fishing guide written by a connection of a faimly freind who plans to write one about maine hopefully at some point and was looking for conections that would write about lakes they knew well about so I read the book to see how he set it up just thought I would ask
