So, you are using your cell phone as a display for your fishfinder, is that correct? If so, will only certain cell phones work? Is it like a flasher or a regular fish finder? Hard to tell from the video but it looks like you could tie a fishing line to the transducer and cast it out while shore fishing, during soft water season, to check what if any fish are off shore, is that correct.
