Furthermore, the AutoChart Live feature allows you to create real-time maps of your favorite fishing spots, which is great for anglers who like to keep detailed records of their fishing locations. One of the drawbacks is that the device is battery powered, which may require additional planning for extended trips to ensure you have enough power. Another consideration is that while the screen size is decent, some users may prefer a larger display for even easier readability. Additionally, the unit's price point may be on the higher side for some buyers, but it does offer a comprehensive set of features that justify the cost.
