【Tested and Working】Game Boy Pocket Sonar Fish Finder This is a rare listing for the Pocket Sonar, a handheld fish finder made by Bandai for the Game Boy a long time ago. Using this, you can easily locate fish while fishing. Simply attach it to the Game Boy's cartridge slot, and it will display the position and depth of fish in the water on the screen in real-time. From fishing beginners to experts, anyone can easily improve their catch. Main Features: • Ultrasonic Fish Finder: Emits ultrasonic waves into the water and detects reflected waves from fish and obstacles. Accurately identifies the position and depth of fish. • Intuitive Display: Displays fish silhouettes and positions on the Game Boy screen in real-time. Makes it easier to strategize your fishing. • Easy Installation: Simply plug it into the Game Boy's cartridge slot and you're ready to go. Compact design for easy portability. • Suitable for a Wide Range of Users: Perfect for fishing beginners to professionals, and also for game fans. Please note that a Game Boy console is required separately. I do not have a Game Boy to test the functionality. No claims or returns accepted. Please note that this item is also listed on other auction sites, so please forgive us if it sells out.
