I have a Fishhunter Pro but I rarely use it for pond fishing, I usually cast and retrieve parallel to the shore where the water is shallow and it works best with 6' or deeper water to find fish. I do find it useful when I go kayak fishing though.
Yea, I would like to use it mostly to have a better understanding of a ponds topography. Knowing where some under water points, creek beds, and structure would be. I know it can also help with water temp as well.
