A spinning reel can be used with many applications from small fish like bluegill to giant tuna weighing over 100 pounds. Setting up your spinning reel with the right line and rod are crucial to making sure you have a successful trip. The line size is critical for the spinning reel you choose and the type of fish you plan on targeting.
Spinning rods and conventional or bait casting rods are different so make sure you have the right rod for your reel. In general, the spinning rod has a larger first guide, which is the guide closest to the reel.
