closed face reels. With a fixed spool, spincast reels can cast lighter lures than bait cast reels, although friction of the nose cone guide and spool cup against the uncoiling line reduces casting distance compared to spinning reels. Spincast reel design requires the use of narrow spools with less line capacity than either baitcasting or spinning reels of equivalent size, and cannot be made significantly larger in diameter without making the reel too tall and unwieldy. These limitations severely restrict the use of spin cast reels in situations such as fishing at depth, when casting long distances, or where fish can be expected to make long runs. Like other types of reels, spin cast reels are frequently fitted with both anti-reverse mechanisms and friction drags, and some also have level-wind (oscillating spool) mechanisms. Most spin cast reels operate best with limp monofilament lines, though at least one spin cast reel manufacturer installs a thermally fused "superline" into one of its models as standard equipment. During the 1950s and into the mid-1960s, they were widely used and very popular, though the spinning reel has since eclipsed them in popularity in North America. They remain a favorite fishing tool for catfish fishing and also for young beginners in general. SpinCast Reel Operation Pressing a button on the rear of the reel disengages the line pickup, and the button is then released during the forward cast to allow the line to fly off the spool. The button is pressed again to stop the lure at the position desired. Upon cranking the handle, the pickup pin immediately re-engages the line and spools it onto the reel. Underspin reel Underspin reels or triggerspin reels are variants of spincast reels that is designed for mounting underneath a standard spinning rod. The reel foot is now located on top of the reel (like a spinning reel), and the line release button is replaced by a front lever. With the reel's weight suspended beneath the rod, underspin reels are generally more comfortable to cast and hold for long periods, and the ability to use all standard spinning rods greatly increases its versatility compared to traditional spin cast reels. Underspin Reel Operation When the line release lever/trigger is lifted up by the forefinger (usually the index finger of the rod-holding hand), the line catch inside the reel disengages and retracts, and the line is free to slide off the
