(H), extra-heavy (XH), or other similar combinations. It is often an indicator of what styles of fishing, species of target fish, or size of fish a particular rod may be best suited for. The power of the rod describes its strength ability, the heavier the rod's power is, the more weight the rod can lift up easily without snapping in half. Being stiffer than light or ultralight rods, the heavy power rods are less sensitive. But the bites from larger fish to heavy lures aren't hard to detect. Ultra-light rods are suitable for catching small baitfish and panfish, or situations where rod responsiveness is critical. Heavy/extra-heavy rods are used in deep sea fishing, surf fishing, or for large-sized game fish. While manufacturers use various designations for a rod's power, there is no fixed standard, hence application of a particular power tag by a manufacturer is somewhat subjective. Any fish can theoretically be caught with any rod, of course, but catching panfish on a heavy rod offers no sport whatsoever, and successfully landing a large fish on an ultralight rod requires supreme rod handling skills but more frequently still ends in broken tackles and a lost fish. It is generally advised to choose rod weights that are best suited to the intended type of fishing. Action The action of a fishing rod refers to the speed with which it elastically returns to the neutral (straightened) position after a flexional load is removed (i.e. the "recoil" or "rebound" speed), and is generally described as being "slow", "medium", "fast", or anything in between (e.g. medium-fast) or beyond (e.g. extra-fast). Contrary to how it is often presented, action does not refer to the bending characteristics (shape of the "curve") of the rod — a fast-action rod can as easily have a more evenly progressive bending curve (from tip to butt) as a tip-only bending curve, although tip-bending rods do inherently tend to have faster action. The action can also be influenced by the length of a rod, the tapering profile, and the blank materials used. Typically a rod that uses a fiberglass composite blank has slower action than one that uses a carbon fiber composite blank. Action, however, is also often a subjective description of a manufacturer. Very often action is misused to note the bending curve instead of the speed. Some manufacturers list the power value of the rod as its action. A
