Review on 🐠 LUCKY Portable Fish Finder - Advanced Handheld Kayak Fish Finder for Boat and Sea Fishing by Tyler Bonnell

Terrible product. Went ice fishing to a Michigan lake first used for crappie. Amazing weed found at 12ft depth, transparency was at bottom, weed was halfway through. The sonar worked and reflected an image full of fish at all depths, but when I looked into the hole there wasn't a single one (in fact, I didn't catch it at that point). Can be useful when fishing on sandy or textured ice but obviously not on shallow areas with weed or texture as it will mark the fish not habitat. Yes, even tried "Sensitivity" on one, still no change. I plan to go back and buy a camera. Lesson learned.
