Steelhead will refer to salmon or trout fish species, which are all known for putting up a good fight. These fish will often fight your line, which means that you have to have the patience to wait for them to tire before you can reel them into shore. Steelhead rods can be used for salmon fishing and are different from regular rods because they are extra sensitive.
The increased sensitivity will allow you to feel for objects in the water and for whenever a fish strikes, nibbles, or bites your bait so that you can quickly set the hook. You want salmon fishing poles to be extra sensitive because this will increase your chances of making a successful catch.
