Hey fellas... I was wondering if you have to have CHIRP to see your bait while fishing a drop shot. I have a Gen-1 Helix 9 and haven't had much time to mess with the settings. I saw a video of Mark Zona on Youtube where he was watching his bait over a school of fish. I think his unit has CHIRP though because it was showing 175-225 Mhz as the frequency.
