Review on 🎣 Lucky Wireless Fish Finder Sonar Sensor: Portable Depth Finders for Fishing, Ice Fishing, and Kayak Fishing - LCD Display Fishfinder by Damon Atonyo

I attached this to a cheap rod to cast out anywhere or keep close by when I was out on the boat trolling with it; mine is John's boat. Fish alarm and water temperature. works perfectly. Fish size and tag for different fish are displayed. In shallow water (less than 4ft) the depth isn't accurate but it does register the bottom and plants, but I didn't quite get what the roughness and smoothness of the bottom in the gauge meant. Can't beat the price, it works and we have fish for it!
