They also extend the reel's life. A reel's smoothness and free rotation can reveal the quality of internal components. You do get what you pay for. Therefore, let your hands be your guide, buy the highest quality reel your budget will allow. Understanding gear ratios is critical for matching reels to techniques.
Gear ratio is the number of times the spool rotates for each handle turn.
The higher the ratio the more line per turn retrieved, but the lower the cranking power. The slower retrieve minimizes fatigue and maximizes lure action. Also use high speed reels for buzzbaits and other topwaters. They'll provide better lure contact during retrieve and better slack line control for hooksets and fighting fish. I am casting to a specific target and only working my bait for about 2 feet past the target.
