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

Absolute rubbish. Didn't work at all, never. I took it out on the bay with my kayak and it showed nothing but a flat line on the bottom. The depth said I was 20 feet deep when the cove was no more than 15 feet deep. There were no features of the ground either, even when I was sure I was over a large structure. Tried again in the sea with the same result. The device said I was in 3 feet of water and never changed, the water temp said it was 110 degrees. Don't waste money.
