To cast a float further, try these techniques: adjust your casting technique and practice your timing. First, make sure to use a long rod for greater casting distance. Next, load your rod with enough power to generate sufficient line speed. Keep your casting stroke compact and smooth, and release the line at the right moment to maximize distance. Avoid excessive force or sudden movements, as they may disrupt the casting momentum. Additionally, using a lighter float can improve your casting distance, as it creates less air resistance. Lastly, consider using a sliding float rig, which allows the float to move freely on the line, reducing drag and increasing casting distance. Regularly practicing your casting technique will help improve your distance over time.
