Portable Fish Finders, and Garmin GPS Software. First, you know that the boat should always be in good running condition. Then, you need the traditional fishing gear. Beyond that, you get to the fun stuff: by incorporating these real-time data into digital map databases accessible via laptop computers, users can determine positions and navigate courses based on continuous updates of their location on an electronic moving-map display. Some fish, particularly in salt water, move to different areas depending upon the phase of the moon and the levels of the ocean tides. So, wherever you are fishing, follow them and know where they are by using your new toy. Click on a category to the left to find the one that interest you, but remember once you get it, you still need to keep your eyes out for floats or bobbers in the water. Don't just focus on your cool new screen; someone may already be where you want to go. But, if they are, don't worry about it--you can find another great place and have fun.
