What is a defining feature of a spinning rod?

A defining feature of a spinning rod is indeed that line guides are mounted on the bottom of the rod. This design allows the fishing line to flow smoothly from the reel and through the guides, enhancing casting distance and accuracy. The placement on the bottom also helps with line management during casting and retrieving, making it easier to use a spinning reel effectively.

While the other options present certain attributes, they do not define what a spinning rod is. For example, mounting line guides on the top of the rod typically characterizes baitcasting rods. The notion that spinning rods are exclusively used for large fish is misleading; they are versatile and can target a wide range of species, including smaller fish. Similarly, the idea that spinning rods cannot handle lures and bait rigs is inaccurate, as they are commonly used for both, making them a popular choice among various anglers.
