How to choose a good Forrest Gump in detail? 0? three

Specific judgment method: hold the pole with your right hand and press your elbow down to make your elbow close to the bottom of the pole. 10-30g, gently adjust the lever, open the tiger's mouth, stretch out the index finger and put it on the lever body, so that the elbow, hand and lever are integrated. Then the elbow joint does not move, and the forearm and wrist shake up and down at an angle of no more than 45 degrees. Feel the rebound of the rocker, the position of the bending point and the strength of the bottom handle relative to the middle and front. Be careful to shake up and down, not horizontally or in other directions. It's like you lift the pole tip and then use it to quickly shock the object in front of you, so that your hand and the pole can move at the same time. When the pole moves to the horizontal position, your arm stops hard to keep the forearm horizontal. Due to inertia, the pole will continue to bend downward, from which we can see the position and elasticity of the bending point. Regarding the position of the bending point, the famous characteristics of rod fishing abroad are: S, F and so on. S (slow) stands for slow tone, which means that the inflection point is backward. This kind of pole mainly uses the whole and the middle and rear parts, which can fully enjoy the pleasure of fighting fish, and the whole pole feels very soft. But poor design will make you feel weak and heavy. F (fast) is a fast tune, the bending point is in front, and the strength of the middle and rear parts is much greater than that of the front end, which is somewhat similar to the combat pole. No matter what kind of fishing, a good rod should be done well: the center of gravity moves backward, the hand feels comfortable, the bending curve is smooth, and there should be only one arc when the rod is shaken. If you try a pole more than 6.3 meters, you will find that the front end fluctuates, the middle becomes a fulcrum, and it doesn't move much, and the back end fluctuates slightly. ) if this phenomenon appears on the luya pole, I suggest you not buy it. The resilience is controlled by the design of the pole, which reflects the mechanical properties of the pole. A good Lu Ya pole, with excellent toughness, can maintain enough "waist strength" after catching fish, so as not to consume too much physical strength in the process of walking fish, and can also improve the fishing speed. When encountering migratory fish, it is of great help to sea fishing. The method of testing resilience: Hold the front handle and the rear handle with both hands, swing the pole from the upward direction to the downward direction, and then suddenly stop with both hands. At this time, the pole then bends, immediately rebounds, vibrates back and forth several times, and then stops. The faster the rebound, the fewer the vibration times and the better the resilience. If you swing the pole for a long time, you will have a feeling. At this time, the feeling of rebounding is like the pole is full of strength, the back is tight, the tip is bent, and the tip is pulled back immediately. It takes a long time to find the feeling. Second, the accessories part of Lu's main accessories are guide wire ring, pulley seat, handle, tail piece, decorative ring, hook and so on. 1, thread-passing ring: the commonly used types are one-legged and two-legged. One-legged split bar is often used for light tuning and straight handle middle tuning. These wire-passing rings are composed of two parts: brackets and porcelain rings. The outermost metal part is called the bracket, which is stamped from a whole piece of stainless steel plate and then flanged in the mold. Because reed shoots will be corroded by seawater and salt spray, corrosion-resistant stainless steel must be used for the support of the wire passing ring. The innermost ring is called a porcelain ring. There are probably two reasons why it is so called: (1) The earliest porcelain rings were ordinary ceramics. (2) At present, most of them are ceramic compounds, including the "SIC" silicon carbide ceramic ring to be mentioned later. The classification of wire passing ring is based on the shape of bracket, the category of porcelain ring and the outer diameter of porcelain ring. Different manufacturers have different naming methods, which leads to different names for the same product. Non-professionals are hard to distinguish. The classification of porcelain rings is relatively standard, which is the same in almost all factories. "SIC" porcelain ring is a new material developed by Fuji in Japan: "silicon carbide reinforced ceramics". Compared with the previous generation of "alumina reinforced ceramics", it has four advantages: higher hardness; Lighter weight; Better heat dissipation and lower friction coefficient. Therefore, it is very popular and widely used in high-grade poles. The criteria for judging the quality of the wire loop are: (1) the strength of the bracket material and the corrosion resistance and weather resistance of the bracket after surface treatment. I have made a comparison of one-legged rings, and the result is that the strength of domestic brackets is weaker than that of Fuji brackets, which will be affected when fishing. (2) Model of porcelain ring. At present, there are four channels for Weihai factory to use porcelain rings: Suzhou, South Korea and Japan (generally, the finished products of the whole line are imported), and a small amount of Weihai local production. What is the quality difference between them? No one or authority makes comments, and everyone decides what materials to use according to the price of the pole. Reed shoots are divided into straight handle and gun handle. The difference between the wire passing rings is that the straight handle generally adopts a single-leg guide ring, with a small total number and a relatively large size; The grips are all leg guide rings, which are numerous and small in size. This is because of their different uses: the straight handle road auxiliary rod is used with the upper guide ring, while the gun handle road auxiliary rod is used with the guide ring (with the drum). If the number of guide rings is small, when the fishing rod is bent, the tight fishing line will rub the fishing rod and affect its use. 2. Wheel seat Wheel seat is used to fix fishing reel, which is mainly divided into plate type and plate type. Among them, tubular ones are divided into two categories: straight handle and gun handle, and there are many sub-categories below, and there are fewer plate-shaped ones. Common rod: the main materials for making tubular wheel seat are ABS plastic, nylon, aluminum alloy and so on. Prices are also rising in turn. The wheel seats produced by many informal manufacturers have one of the biggest defects: the groove is too small, which leads to the fishing wheel not being installed! This kind of situation mainly happens on the pole with relatively small tonality, and I have met it several times. Therefore, when you buy Lu, you'd better take a fishing boat for an experiment. Plate-wheel seats are basically useless in China, but they are available abroad. Method for judging the quality of tubular wheel seat: (1) First look at the appearance, whether there are defects, flying thorns, burrs, smoothness and flatness of plane parts. Because the tubular wheel seat is an injection molded part, the product has a mold joint, a gate and an ejector. The quality of these parts reflects the quality and manufacturing level of the mold. Once there is a defect, the mold must be replaced. (2) Look at the feel again: turn the nut by hand and feel the resistance. The smaller the resistance, the more uniform and the better the quality. Many poor-quality wheel seat nuts have different resistances in different parts, which makes them feel "loose and tight". (3) There is also a groove in the threaded part on the back of the wheel seat to prevent the fixture from dislocation. Hold the clip connected to the nut by hand and turn it. If the fixture rotates away from the groove, the quality will not pass. The main purchase channels of wheel seats in Weihai are: local factories, Taiwan-funded enterprises in the south, South Korea and Fuji in Japan. Price and quality are also rising in turn. Japanese Fuji accessories are generally used in high-grade poles. Third, poles with the same tonality, weight and specifications vary greatly due to different workmanship, and sometimes even exceed the cost of the pole itself several times! All poles are like this. So, don't feel incomprehensible when you see that the parameters are almost the same, but the prices are quite different. I think there are the following points to judge the quality of a Lu Ya bar: 1, the straightness of the material. Lu is generally long, and some single sections are as long as 2.4 meters, which brings great difficulty to the production of materials! Because making materials is a physical/chemical reaction process, with the changes of temperature and internal stress, it is almost impossible to ensure that materials are straight. When choosing Luya pole, insert the pole, aim at the guide ring, hold the pole with both hands and put it on your chest, slightly raise the pole tip, look for a white or gray background to avoid interference, pay attention, and keep your eyes on the pole tip (which is usually easy to bend) to see the bending. Sometimes you can see more bending by rotating the pole. Obviously, bending is not necessary, but it is impossible to be completely absent (about 2000 yuan or more). This can't be quantified, it depends on your own feelings. 2. The material "spine", especially the grips, should be inspected. You may wonder: how can there be a "spine" in the material? The English name of "spine" here is "SPAN", which refers to the relatively rigid area in the longitudinal direction of the material. This is like sticking a steel bar with a thickness of 1mm and a width of 2mm on a steel pipe with a wall thickness of 2mm, and closely bonding the steel bar and the steel pipe by welding and other methods, so when bending the steel pipe in the future, it will be more difficult to bend in this direction than in other directions. Theoretically, all materials have "thorns", but the degree and depth are different. We often see that the propaganda of "uniform wall thickness" is to avoid "thorn", and the density difference of fiber arrangement can also cause "thorn". Check the "spine" method: insert the pole, aim at the guide ring, hold the pole with your left hand, about 1 m away from the top, gently place the index finger of your right hand on the thinnest end of the pole, and then slowly press down to bend the pole. When your fingers feel strong, stop pressing and slowly turn the rod back and forth with your left hand. You will feel the tension at one angle is high and the tension at other angles is low. So we can find the spine. For a straight handle bar, the "spine" should be at the top (the back of the guide ring), and the handle bar is just the opposite. If you don't find the correct "spine" or "spine" at all when you tie the guide ring, then the pole will be distorted when it is stressed, which will seriously affect the use! 3. There are many guide rings in the guide ring straightness rod, and the rod body is thin, so the alignment of the guide rings has become a technical problem. Generally speaking, factories with a long history and rich experience are better, while new factories are relatively poor. The identification method is the same as the straightness of the previous identification materials, and will not be repeated here. 4, the guide ring is tied, and the painting quality is the earliest. After the FRP rod is tied, straighten the guide ring first, then burn the burr with alcohol lamp and apply primer and UV paint. The so-called UV paint is a kind of photosensitive paint, which will cure rapidly under ultraviolet irradiation. The advantages of UV paint are high efficiency and high brightness. But there is one of the biggest disadvantages: poor toughness, low strength and poor adhesion. It will burst when subjected to a strong force. Later, UV paint was gradually replaced by epoxy resin (thick paint). The advantages of epoxy resin (thick paint) are: high strength, strong adhesion, high surface fullness, good feel and appearance. However, the efficiency of epoxy resin (thick paint) is lower than that of UV paint, which requires a certain curing temperature and a certain cleanliness of the operating environment. So there are still many small factories and low-grade poles still using UV paint. Need to remind everyone: in order to ensure long-term use, please be sure to choose poles with epoxy resin (thick paint) technology (except DIY, of course) to judge UV paint and epoxy resin (thick paint): 1. According to the different adhesion, you can obviously see the larger recoverable deformation by pulling the guide ring bracket with your fingers. If it is UV paint, you can hear slight deformation. 2. Gently press hard objects (nails, keys, etc.). ) in an inconspicuous position. If it is UV paint, it will delaminate on thin ice with the bottom layer, while epoxy resin (thick paint) will not delaminate, and indentation will appear, but it will disappear after a while. The quality requirements for wire binding and painting mainly include the following points: 1, wire binding should be dense and not exposed. 2. The starting and ending edges should be aligned. 3. The coating thickness should be uniform, the edge should not be too long, and the edge should be neat. 4. No bubbles, burrs, protrusions, foreign bodies, etc. On the painted surface. 5. The line type should be full and beautiful, and there should be no grooves and sagging. These things are easy to say, but it is very, very difficult to be all right and impeccable. Including Japanese brands such as S, D and G, there is no guarantee that all of them will be in place. Because these are all manual operations, not mechanized production. Fourth, finally talk about the handle: the handle materials mainly include EVA and cork. Because more than 85% of cork materials for fishing rods in the world are imported from Portugal, cork resources are in short supply and expensive. Cork 2 is divided into pure natural cork, wrapped cork, compressed cork and rubber cork. According to the surface quality, pure natural cork can be divided into grade C, grade B, grade A, grade AA, grade AAA, wrapped cork subcontracted EVA, wrapped compressed cork and so on. So how do ordinary consumers tell? Cork and EVA are clear at a glance, and their appearance and hardness are very different, so you can identify them. In order to make full use of the feel and appearance of natural cork, manufacturers have come up with a method of "wrapping cork": the outside is pure cork skin, but the inside is EVA, compressed cork and other materials, which are bonded together through a certain process. Although this method solves the dilemma of cost and appearance, it never uses all high-grade poles. But how to distinguish pure natural cork from wrapped cork? If it is a cork wrapped in EVA, you can stack it with your thumb and press it hard. If you can feel obvious elastic deformation, it is wrapped by EVA, but you can hardly feel elastic deformation, so it is not wrapped by EVA. Compressed cork refers to the mixture of small cork particles and special waterproof glue, which is pressed at high temperature. Hardness is slightly lower than pure cork, but the price is much higher. Sometimes used on middle and low-grade poles, it is often used to match the decorative front seal or decorative back seal of pure cork. If compressed cork is packed, it is basically impossible for ordinary consumers to identify it unless the surface is cut. Basically all the accessories, as well as the remaining hooks, tails, decorative rings and so on. It can be distinguished by appearance, so I won't say much. In short, one shot involves many aspects. When buying, you should decide which aspects are primary and which are secondary according to your actual needs. For ordinary consumers, tonality and feel are the first, the quality of accessories is the second, followed by finish and workmanship. But for the high-priced pole, it should probably be reversed, because the design strength of big brands is good, and probably won't bring products with wrong tonality and bad feel to the market. Even if the tonality and feel of each brand are different, the difference is so small that ordinary people can't feel it.
