I have an older Fishin Buddy from when they were still made by Bottom Line. My fishing partner has a vex. We use the two together to narrow down the location of the fish. I agree though that my Buddy lies to me a lot, telling me there are fish where the vex says there's none. It does seem to give me an accurate depth and the side finder has led us to a few schools of fish. I'd say it has its uses but I'd much rather have the vvex.
