Using a baitcasting reel requires proper technique to prevent backlash and maximize casting distance. Start by adjusting the spool tension knob to control the release of the line and set the brake system to minimize the risk of tangles. When casting, hold the line with your thumb, press the release button, and then smoothly swing the rod forward, letting the line flow off the spool. As the bait reaches its target, use your thumb to apply gentle pressure to slow the spool and prevent a backlash. With practice, you can fine-tune the settings and improve your casting accuracy and control.
