line weights (size #0–#3) have also long been utilized for ultra-light fishing, as well as to protect the thin-diameter, lightweight end section of leader, or tippet, used in this type of angling. Ultra-light spinning and casting rods are generally shorter ( is common) lighter, and more limber than normal rods. Tip actions vary from slow to fast, depending upon intended use. These rods usually carry test fishing line. Some ultra-light rods are capable of casting lures as light as – typically small spinners, wet flies, crappie jigs, tubes, or bait such as trout worms. Originally produced to bring more excitement to the sport, ultra-light spin fishing is now widely used for crappie, trout, bass, bluegill, roach, perch, bream, pumpkin-seed, tench and other types of pan fish. Ice rods Modern ice rods are typically very short spinning rods, varying between in length. Classic ice rods – still widely used – are simply stiff rod-like pieces of wood, usually with a carved wooden handle, a couple of line guides, and two opposing hooks mounted ahead of the handle to hand-wind the line around. Ice rods are used to fish through holes in the cover ice of frozen lakes and ponds. Sea rods Sea rods are designed for use with fish from the ocean. They are long, (around on average), extremely thick, and feature huge and heavy tips, eyes, and handles. The largest of sea rods are for use with sport fishing boats. Some of these are specialized rods, including shark rods, and marlin rods, and are for use with very heavy equipment. Surf rods The most common type of sea rods are for surf casting. Surf casting rods resemble oversized spinning or bait casting rods with long grip handles intended for two-handed casting techniques. Generally between in length, surf casting rods need to be longer in order for the user cast the lure or bait beyond the breaking surf where fish tend to congregate, and sturdy enough to cast heavy weighted lures or bait needed to hold the bottom in rough water. They are almost always used in shore fishing (sea fishing from the shoreline) from the beach, rocks or other shore feature. Some surfcasters use powerful rods to cast up to or more of lead weight, artificial lures, and/or bait over . Trolling rods Trolling is a fishing method of casting the lure or bait to the side of, or behind,
