Review on 🐠 Garmin 010-01550-00 Striker 4 GPS Fishfinder: Chirp Transducer and 3.5" Display by Jeremy Floyd

Very simple and intuitive user interface. This works exactly as I had hoped. However, there are two points that are sometimes overlooked. First, this device must be connected to a 12-volt power source, such as a car battery or one of those car battery power adapters. So if you want to use it in a kayak, you need to plan for a power source. Second, the screen/keyboard is not waterproof at all. If it may rain or splash, you will need a zippered bag or similar to cover the item.
