Back in 1998 Bandai released the Pocket Sonar for the Game Boy. Yes, a sonar device that can find fish that works on an original Game Boy. Sadly it was only released in Japan and there was also a version for Bandai's own portable gaming system the Wonderswan. If you want to know more about this odd little Game Boy accessory, The Gaming Historian Norman Caruso's latest video not only talks about the device but he actually tests it out to see if it can really help find fish.
