The guy beside me with a flasher shows bottom, bait and fish. I think the bottom may be featureless(flat sand) but I don't see my bait as he does his. There weren't many fish in the area when I tried my Hawkeye so I'm not sure if they register either.I tried changing sensitivity with no luck. The depth reading appears to be accurate according to line dispensed on bait.But I cuoldn't see my bait. Is this normal?
