Modern rods are made of fiberglass or carbon fiber. CFRP rods are lighter and have better action, but they are more expensive. Composite materials contain a mixture of graphite fibers and fiberglass. The lightest carbon fiber rods have very thin walls that can be easily damaged. CFRP is a fairly fragile material, it does not withstand shock loads poorly. Even the impact of a load during casting or an excessively sharp swing can cause such a rod to break.
Action refers to the bending curve of the rod under load. A rigid rod has a fast action – the whip is bent and one or two knees following it. Soft, with a slow (slow) action, characterized by a longer length of the rod bending under load. Why do you need to produce fly rods of different construction? The tuning determines the features of the rod operation. For example, slow ones allow you to carefully remove large or small fish, reducing the likelihood of their coming off and breaking a thin leash. They are good at casting light rigs with low float capacity. Their disadvantages include low efficiency during accelerated playing. A soft rod is not capable of quickly pulling a fish weighing even 100 g out of the water.
Fast action rods are more aggressive when playing fish, but at the same time, in a situation of high-speed fishing, time is not wasted on long-term fatigue of the prey. Rods of this type are worse at casting light rigs, but they allow you to make a short hook-up, protecting a thin leash. If you have a fast rod, the physical energy required when casting medium-weight and heavy rigs will be minimal. The longer, heavier and softer the rod, the more difficult it is to perform a whipping cast, in which the rig lies flat on the water. Therefore, just such a cast allows you to avoid overwhelming the rig when fishing in shallow and overgrown places. Manufacturers combat unwanted rigidity by incorporating a soft rod into the rod.
By this term we mean a margin of safety. Sometimes power is confused with rigidity, meaning that the latter is not a system, but the load necessary for bending. A powerful, difficult to bend rod can not only work under a huge load, but also has a soft slow action, that is, it bends smoothly under significant load almost along its entire length. Conversely, a rigid rod may only be suitable for ultra-thin rigs and small fish. Power directly determines such a fishing characteristic as load. The load is not only the absolute size of the fish, but also the nature of its resistance, the style of playing, the possible presence of obstacles and the careful care of the tackle. The less time the angler spends on caring for the tackle, the more powerful and reliable the purchased product should be.
The performance that determines how a fish is played has a lot to do with the softness and elasticity of the whip. Given this fact, manufacturers make thin rod tips with a diameter of up to 0.6 mm. Most often, the tip of the whip is about 2 mm in diameter. In a duel with a large fish, one of the middle knees is more likely to break than the tip. Many anglers are unable to buy an expensive quality rod. Cheap models made in China or Korea may be fine for fishing with thin lines, but will require replacing their whip with a softer one with a thinner tip. On sale separately there are carbon fiber whips, the cost of which is much lower than the assembled rod of the corresponding class.
Recently, many telescopic rods have been sold in stores, equipped with guides and a spinning-style reel holder. Fitting rings usually degrades the action of a classic fly rod, but at the same time, such rods provide a number of advantages and therefore are very popular with anglers.
