Down imaging?

[Canadian Black Bears]

I have a hummingbird and it is wicked in the small lakes we fish. We use it as a depth finder as the lakes we fish have a lot of shallows with rocks. We don't use this for deep water or huge open water just the small lakes which are approximately 2-3 miles long. Most likely this doesn't help ya out much but just wanted to let ya know the Hummingbird is a wicked product.
