The Fishin Buddy fishfinder is very user friendly - its One-Touch control provides access to all the advanced features, even Selective Fish ID+. For most anglers, all most anglers will ever need to do is power on the fish sounder unit and fish! The Fishin? Buddy automatically determines depth and makes adjustments to keep the bottom and fish visible on the fish locator display.
Here are all the technical details and features of each of the Humminbird Fishin Buddy portable fishfinder units. The major differences between the three models are the display, sonar type, transducer mounting pole and, of course, the price. Basically, the Humminbird 120 Fishin Buddy has a little better screen (higher grayscale level and more pixels) than the 110 in addition to side imaging sonar. The Fishin Buddy 130 also has a step up in greyscale and pixel resolution than the 120 in addition to a telescoping transducer pole that extends to 40". Then, the next step up, the Humminbird 140C Fishin Buddy, the only difference is the color screen.
