And it shows the profitability of each leverage based on the entered data. You need to set the odds for both outcomes and specify the total amount of the bet.

The calculator will indicate the size of the amount for each leverage and profit in percentage and absolute values. The algorithm allows you to switch between surebets for two and three outcomes.

Arbitrage players use the calculator in live In-match bet when time to make a decision is limited. The program instantly performs the necessary calculations, freeing the player from manual calculations. A delay in live will result in a change in the coefficient and a missed situation. Even worse, if the bettor manages to close only one shoulder. Then, instead of a guaranteed profit, he gets a risky situation.

Sports betting arbitrage - what is it?

Fork - a situation when bookmakers evaluate the event differently and allow the player to get a guaranteed profit by betting on opposite outcomes. They are also called arbitrage rates. To play, a bettor will have to create accounts at least in two bookmakers (in practice, there are many more accounts, which increases variability and coverage).

Example. Bookmaker “A” gives odds of 2.15 for the victory of Rafael Nadal in the match against Novak Djokovic, and bookmaker “B” gives odds of 2.07 for the victory of the Serb. If you put down 1000 rubles for each of the outcomes, then the profit will be guaranteed for any outcome of the match.

A primitive example clearly shows how bettors make profit from surebets. But today, such situations are extremely rare, as companies monitor each other's lines, excluding the possibility of surebets.

The section will tell you how they can make a profit if you use the right strategies and calculators.

Arb calculator in live

The situation looks different in live. When playing online, the bettor finds a bunch of arbitrage situations that arise in different bookmakers. Live makers do not think about the fact that by placing a quote on the outcome of an event, it can be arbitrage with a different quote in another bookmaker. Therefore, the program for calculating surebets is an indispensable tool in the hands of an arbitrage player.

Sanctions are a sign of an average-level office. The most reputable bookmakers do not fight arbers. On the contrary, they publish calculators on their website. Their own, which will help to instantly calculate and calculate the profitability, the project website also offers.

The use of braided lines, no doubt, expands the possibilities of the angler. High strength, low stretch, flexibility, resistance to cold and salt water - qualities, of course, are useful. In the recently so popular fishing on jig heads with soft lures, these lines simply made a splash.

Instead of a fishing line Ø 0.28 mm, you can put a line of only 0.12 mm. The bait will reach the bottom sooner, the "interference" from the current will decrease, the tackle will become more sensitive, the range of the speed of the wiring will be wider.

And how much does the reliability of hooking increase with distant casting Or deep sea fishing?

Braided line makes the tackle elegant and sporty, as it allows the use of reels with a smaller spool diameter, the lightest baits.

One bad luck. Very expensive. It is unprofitable and unjustified to wind 300 meters of a beautiful cord just because that is how much a reel can hold. This is what forced the German fisherman Stefan Bork to do simple but important calculations.

fishing line- nothing more than a very long and thin cylinder. We will calculate its volume and thus the space it takes on the spool using the formula: the total capacity of the spool (RK) is equal to the number 0.7854 (constant) times the square of the diameter of the line in millimeters (d × d) and multiplied by the length of the line in millimeters (L ). Briefly, this can be written as follows: RK = 0.7854×d×d×L. Example: a reel with a spool capacity of 100 meters of 0.50 mm thick line has a total capacity according to this formula 0.7854 × 0.50 × 0.50 × 100 = 19.635.

The optimal length (L) of a line of any diameter can be determined by dividing its RK by 0.7854 and the square of the desired line diameter: L=RK:(0.7854×d×d). For example, if we want to fill the spool of our model with 0.25 mm thick braided fishing line, then the length will be as follows: 19.635: (0.7854 × 0.25 × 0.25) = 400 meters.

This result, as experience shows, is quite close to the actual capacity of the spool, even if the calculation does not take into account such indicators as line tension during winding, calibration consistency, evenness and density of coils.

But a line length of more than 200 meters is almost not required when fishing in freshwater reservoirs. Fully filling the spool with braided line means that much of the costly line would for a long time only serve as a substrate for the part of the line that comes into direct contact with the water. This function may well be performed by monofilament line, which should have at least the same strength and therefore about twice as much thickness as braided.

For example, if we decide to wind 150 meters of 0.25 mm braided line on a spool with a capacity of RK = 19.635, then the question arises of what length of filler line is needed. This can also be calculated using the above formula by dividing the total spool capacity by mainline capacity (RKhs) and filler line capacity (RKfs):

RK = RKhs + RKfs, or RKfs = RK-Rkhs

The capacity for the main line RKhs in our example is: 0.7854×0.25×0.25×150 = 7.363.

Therefore, the capacity for filler line will be: 19.635 - 7.363 = 12.272.

In our example, we use 0.55 mm monofilament line. Its required length according to the calculation is:

L \u003d RKfs: (0.7854 × d × d) \u003d 2.272: (0.7854 × 0.55 × 0.55) \u003d 51.65, that is, about 50 meters.

In other words, spooling would be optimal using 50 meters of 0.55mm monofilament line and 150 meters of 0.25mm main braided line. Compared to continuous winding of 0.25mm braided line onto a 400m spool, the material benefit is clear.

Since even an average spinning reel can hold much more braided line than is needed for freshwater fishing, monofilament filler line creates significant savings opportunities. It is not necessary to delve into mathematical formulas every time. With the help of the table, you can quickly find many quantities.

In our text example, the known reel capacity is 100 meters of 0.5 mm line. The corresponding value (RK) in the table is 19.635 (light blue). If 150 meters of 0.25 mm main line is wound on the spool, we find the corresponding RK value (red color) using the indicator 7.363. To determine the amount of filler line, we must subtract this figure from the RK value of the reel (19.635-7.363=12.272). In the RK column in the table, we find the indicator closest to this value - 12.566. The yellow line shows the appropriate lengths of filler line. If for this purpose we want, as in our example, to use a 0.55 mm fishing line, its length according to the table will be 50 meters.

Note. If the specified (known) capacity of the coil is not given in the left column, then RK can be determined from the table. A reel with a capacity of, for example, 280 meters of 0.3 mm line has the same total capacity (blue line) as our reel model. If, nevertheless, the exact number cannot be found, you can be content with the indicator that is closest to the one you are looking for.

The diameter of the braid indicated by the manufacturer on the spool is a very approximate value that may not correspond to the real one at all. After all, the same fishing line, even from premium brands, has an uneven thickness. The diameter of the braided cord is not a constant value along the entire length of the fishing line, but the value indicated on the spool is the average value of the diameter of the fishing line.

The problem also lies in the fact that it is almost impossible to accurately measure the diameter of the braid, and each of the cord manufacturers uses its own method of calculating it, based on the ratio of the mass of the material and other parameters of the multifilament fishing line.

Braid diameter

What does the question “what braid diameter to choose” mean if it is not specified for what?

It means absolutely nothing without specifying the parameters of the tackle and the method of fishing. Moreover, if we talk about braid for spinning, for example, then here the diameter of the braid can also fluctuate over a wide range. Ultralight for spinning is thin delicate cords, for jig spinning it is much stronger, depending on the weight range of the lures used. What braid diameter to choose in each case? Let's look into this in more detail, but first, a few facts about the braid.

Braid Facts

Braid under the microscope

What you need to know about braided line:

• the braid has almost no stretch (zero stretch), which is very good for controlling the bait and registering a bite, and not very good for playing the fish;
• braided cord is much stronger than any monofilament line (monofilament);
• depending on the type of weaving, a multifilament thread is round and flat in cross section (a round braid sails less and sinks faster);
• braided fishing line, especially without impregnation, absorbs water, so it cannot be used in winter (with the exception of special cords and impregnated from freezing);
• braided line very quickly cuts through low-quality rod winding rings;
• not all knots for ordinary fishing line are suitable for braided line (it has great slip);
• Braided line is more expensive than regular line, but it's worth it.

spinning braid diameter

What braid diameter to choose for spinning? You can endlessly rant on this topic, saying that everything is not so simple here and other “blah blah blah”, but we will try to be more specific.

The diameter of the spinning braid depends on the following parameters:

• test your spinning and reel class;
• the weight of the baits used.
• the size of the intended fish you are going to catch;

When it comes to choosing braided fishing line for spinning, it should be borne in mind that it is two or more times stronger than usual. Therefore, if you used monofilament with a diameter of 0.3 mm, you should choose a braid with a thickness of no more than 0.15 mm. You will be surprised how far your bait flies.

Braid for pike spinning

“What kind of braid for pike,” is what they often ask in stores.

Braid for pike? Are you seriously? Okay, let's revisit the analogy with regular fishing line. If earlier you caught pike up to 3-5 kg ​​and monofilament with a diameter of 0.3 mm was enough for you, then a braid with a thickness of 0.08 - 0.1 mm can hold such a weight. Braid with a diameter of only 0.1 mm will definitely go for pike up to 5 kilograms.

A thicker braid will be able to hold more, but the casting distance decreases with thickness and is very difficult to break when hooked. You should not get carried away with excessive thinning either, since the thinner the braid, the faster it wears out and serves less. Here you need to find a compromise.

For pike fishing up to 5 kg, a braided line with a diameter in a wide range is suitable - from 0.06 mm and thicker. For light baits and ultralight spinning we use up to 0.08 mm, for a medium weight jig a braid up to 0.14 mm is suitable, for heavy jig spinning you should choose from 0.14 to 0.18 mm. So we figured out what kind of braid for pike is needed.

Conclusion: the diameter of a suitable braid for spinning is more tied not to the type and size of the fish, but to the power of the rod and the weight of the baits used. It doesn't matter what you will be catching - perch, pike, zander or other fish, it is important that the braided line matches the power of the tackle as a whole (spinning + reel + bait).

Braided fishing lines from different manufacturers can vary significantly in breaking load for the same diameter, so this must also be taken into account.

Braided fishing lines for spinning - video

If you know very little or nothing about braided fishing lines and want to learn more, we recommend watching the film by the Shcherbakov brothers dedicated to choosing a braided fishing line for spinning and about braiding in general:

Feeder braid diameter

All that we have said about braided line for spinning is generally true in the choice of braided fishing line for feeder gear. Only instead of the power of spinning rods, the power of the feeder gear and the weight of the feeders used should be taken into account. Many parameters of a braided fishing line that are important in spinning are not taken into account for a feeder.

The main thing is that the fishing line can withstand the critical load that occurs when casting the feeder.

To cast a feeder weighing 100 grams over 50-60 meters, the peak load for the cord is no more than 5 kg, and for a 150 gram load - no more than 7 kg. These are approximate figures that can be used as a guideline when choosing a cord according to the test breaking load.

1. For fishing without a current with feeders up to 30 grams, a line with a diameter of 0.05 mm with a shock leader is suitable.
2. For fishing in the current with feeders up to 150 grams - braid with a diameter of 0.17 mm.

How to measure braid diameter

It is very difficult to measure the diameter of the braid

Measuring the diameter of a braided fishing line is not as simple a task as it might seem at first glance, but almost solvable.

Why can't you accurately measure the diameter of braided line? The thing is that, unlike monofilament, a braided cord consists of many ultra-thin threads connected by a special weave with or without impregnation. Even with a slight compression of the cord with a measuring tool (micrometer), we get incorrect measurements at the output. In addition, the braided line may initially have not a round but a flat section.

It would seem: if we know the number of threads in the braid, what could be easier than taking and “adding up” the diameters of all the threads and getting the total diameter of the braided cord? Theoretically, knowing the cross-sectional area of ​​​​each thread in the cord, it is possible to determine the total diameter of the cord, but the problem is that the diameter of each thread differs significantly from each other and is different along the entire length. And moreover: who said that the number of micro-threads is generally known and that it is a constant value? So this measurement method is also very inaccurate.

So how, nevertheless, to measure the diameter of a braided fishing line?

We can use a little trick: if we tie an ordinary single knot on a braided fishing line and tighten it, its density will allow us to use a micrometer and find out the size of the knot. If you tie several knots on one fishing line, their size will differ from each other within the margin of error. Thus, we can take the thickness of the knot as the conditional size of the thickness of the braided fishing line.

If we divide the thickness of the knot by two, we get the diameter of the braided thread close to the real one.

It should be understood that this method does not give us absolutely correct result, but allows you to compare the thickness of different braided lines with sufficient accuracy. Having a “reference” of a braided thread on hand, let's say 0.15 mm in diameter, and knowing the exact size of a simple knot on it, we get the opportunity to compare.

The Shcherbakov brothers even filmed a video about this.

The number of bearings provided in the design of the reel. Bearings are used to reduce friction of rotating parts, which, on the one hand, protects such parts from wear, and on the other hand, reduces excessive effort expended when the handle is rotated. Accordingly, than more bearings- the more friction units are protected and the better the coil is “optimized”; this parameter is a good indicator of the overall class of the product. At the same time, it is necessary to evaluate different models taking into account their purpose (see "Type").

So, in fly fishing reels, even quite expensive ones, 1 bearing is usually provided - at the point of installation of the drum on the bracket, designed for attachment to the rod. This is actually the only significant friction point, so more bearings are simply not required. For multiplier reels, this number varies from 1 for relatively simple options to 6 - 7 for premium ones. And in inertia-free bearings, the number of bearings can reach a couple of dozen.

clutch

The friction type describes the location of the friction brake mechanism provided in the reel and, accordingly, its adjustment knob.

The friction brake itself is responsible for loosening the reel at a critical force: when the load increases significantly, a properly adjusted friction clutch pits part of the fishing line, preventing it from breaking. But the specific actuation force may differ: some fishermen prefer to loosen the brake as much as possible, allowing the fishing line to slip with rather weak jerks, while others, on the contrary, tighten it, allowing operation only when dangerously approaching the breaking load. And in some situations, you need to change the settings right in the process of playing. The convenience of such a reconfiguration is one of the points that is affected by the type of clutch. In addition, design features may be due to the purpose of the coil. Specific options might be:

Spool capacity

The amount of line that can fit on the main spool of a reel with normal winding. It is indicated as a ratio of two numbers, the first of which corresponds to the length of the line being wound in meters, and the second to the thickness in millimeters: for example, the numbers 200 / 0.45 indicate that up to 200 m of line with a thickness of 0.45 mm can fit on the reel.

For different types fishing there are recommendations on the optimal value of this parameter; they can be found in special sources. Here we note that the capacity of the spool is indicated exclusively for a smooth fishing line; when using a braided cord, the actual performance may differ markedly.

Built-in line counter

The purpose of this function is generally clear from the name: it allows you to determine the amount of reeled line with a fairly high accuracy (for example, up to a foot). Most models with line counter refer to multiplier (see "Type") and are designed for trolling, where it is important to lower the bait to a strictly defined depth. This is especially true for sea fishing. The meters themselves can be analog or digital: the former usually do not require power supplies and are generally considered more reliable, the latter, as a rule, are much more accurate and have more extensive functionality (for example, they may provide for switching units of measurement between feet and meters).

Automatic line winding

Reels with this function are equipped with a built-in electric motor that can rotate the spool, eliminating the need for the fisherman to turn the handle himself. The advantage of such devices is obvious: fishing becomes less tiring. In addition, the design may provide for specific additional features- for example, automatic winding of a strictly specified amount of fishing line. On the other hand, the automatic winding system significantly increases the weight, dimensions and cost of the product, and there is a real need for it only in the most difficult types of fishing, where you have to regularly wind a large amount of fishing line with considerable effort. Also, do not forget that the motor requires a power source to operate. As a rule, an external battery or the onboard network of the vessel is used for this, because. batteries of the required capacity and power simply would not fit into the coil itself. In light of all this auto winding has not received much distribution - it is found mainly in top models of multiplier coils (see "Type"), designed for sea ​​fishing.

Coil material

The material from which the base of the coil is made is a part of the structure on which the spool and other mechanisms are installed.

Plastic. Plastic has a low cost, low weight, besides it is resistant to corrosion and completely immune to salt water. At the same time, this material is easily scratched, its strength is relatively low, and under the action of ultraviolet radiation in some grades of plastic it is even more reduced. As a result, plastic is mainly used in coils. entry level not designed for difficult conditions and high loads. As a rule, its quality directly depends on the price of the product.

Graphite. Most often, this term refers to a relatively simple type of carbon fiber, which has a low cost and can be used even in budget-class models. At the same time, with a small weight, graphite is somewhat stronger and more resistant to certain influences than plastic, and therefore is also found in more expensive products. The quality of this material may also vary depending on the price of the coil.

Carbon. Another type of carbon fiber, higher grade than graphite. Carbon combines high strength, flexural stability and durability under stress with extremely low weight; in addition, it is completely chemically inert (does not corrode) and tolerates ultraviolet radiation, temperature extremes, etc. well. The main disadvantage of this material can be called a high price, due to which ... it is used mainly in premium models. We also note that carbon requires quite careful handling, because. does not take a hit well.

Composite. Composites are materials that combine several separate components that are not mixed with each other (unlike, for example, alloys). In coils, this term most often means a combination of the graphite or carbon fiber described above with fiberglass. Fiberglass, despite the name, bears little resemblance to ordinary glass - it has high flexibility and can withstand bumps and falls without any problems; therefore, the combination of this material with carbon reduces the fragility of the latter. And in the "bundle" with graphite, fiberglass somewhat increases the strength of the entire structure. The composite base can be found in models of different price categories - this is due to the difference in the quality of the components used.

Aluminum. The main advantage of aluminum alloys can be called high strength, due to which this material can be found even in "large-caliber" coils designed for strong and heavy mining. However, there are simpler options - again, aluminum alloys come in different types, and their characteristics usually depend on the price. By weight, this material, if it surpasses plastic, is not much, and its corrosion resistance is very good. Of the obvious shortcomings, one can only note a rather high (in general) cost.

Magnesium. Magnesium-based alloys are premium materials. Their main feature is extremely a light weight combined with high strength and reliability, which allows you to create powerful and at the same time quite light reels. On the other hand, such products are not cheap, and the material itself does not tolerate contact with salt water, and in general its resistance to corrosion is relatively low (which requires the use of special coatings).

Main spool material

The material from which the main spool (drum) of the reel is made. The term "main" is due to the fact that some models can be equipped with several interchangeable drums; see below for details. The materials used may be:

- Plastic. The most simple and inexpensive option. In terms of strength, plastic can lose to more expensive materials, but for those coils where it is used, this is not decisive: such models are usually not designed for high loads, and a relatively short service life is compensated by a low price. In addition, this material weighs a little - and this means low inertia. At the same time, when buying a spinning reel with a plastic spool, you should take into account its poor compatibility with braided cords: a rough cord runs along the plastic side with great friction, which negatively affects both the casting distance and the durability of the reel. But with fishing lines, such drums work without problems.

- Graphite. In most properties, this material is similar to the plastic described above (including poor compatibility with braided cords); it is slightly more durable and durable, as well as, accordingly, higher cost.

- Aluminum. Aluminum-based alloys used for spools are characterized by fairly high strength combined with low weight, besides... e in spinning coils they can work normally not only with fishing line, but also with braided cords. With all this, such materials are somewhat more expensive than plastic and graphite, but not so much as to "raise the price to the skies." As a consequence, aluminum is found in a wide variety of coils, from relatively simple and inexpensive options to powerful premium models.

Magnesium. The main advantage of magnesium alloys is considered to be very low weight, providing minimal inertia with high strength (surpassing even the aluminum alloys described above). At the same time, it should be borne in mind that magnesium is very sensitive to certain corrosion factors, in particular to salt water - some manufacturers directly prescribe in the terms of the guarantee the inadmissibility of contact with it. Yes, and these spools are very expensive. Therefore, this option is used mainly in premium models.

Additional spool material

The material of the additional spool (drum) supplied with the reel.

Additional interchangeable spools are provided to expand the capabilities of the reel: if necessary, you can quickly replace the fishing line with tackle of a different thickness (or the same one instead of a broken one), install a reduced drum to increase the casting distance, etc. As for the materials for such spools, they do not differ from those used in the main drums; see the corresponding paragraph above for more details.

The weight

The total weight of the reel (only the device itself, without fishing line). This parameter is important, first of all, for those who select class equipment. "ultralight"- in such gear there is a struggle, as they say, for every extra gram. In other cases, you can not pay special attention to weight.
