Ranking: The 4 best bars
To achieve the perfect circle and arc you need a quality compass. But it is not easy to know which ones have this characteristic. So we went searching and separated in the Ranking below the best options of the market so that you can choose one without fear, check out:
It is believed that the compass appeared about 300 BC and is still a tool widely used not only at school, but also in the daily lives of some professionals.
This is very useful and easily accessible equipment. However, some are still confused about its characteristics and use. And it is to solve all doubts that we bring in this Purchase Guide the most important information about the product. Come on?
What is a compass and what is it used for?
The compass is a drawing tool used in geometry to create circles, arcs, mark a segment on a line, find the center of a circle and much more.
It consists of two articulated rods joined by a point, very reminiscent of a clamp. The end of these rods is different from each other, with a dry tip on one of them, composed of a metal needle, and on the other a graphite, which will be responsible for marking the design.
Both rods are opened at an angle of 180º and there are options in which instead of using the graphite that comes with the product it is possible to attach pencils or pens.
The compass is part of the list of school supplies for all children, but it is also widely used by those who work in areas that require technical drawings such as locksmiths, design, architecture, engineering and crafts.
What are the advantages and disadvantages of the compass?
With the compass it is possible to create perfect arcs and circumferences in an easy, simple and quick way. It is the best tool for this and for that very reason it has been used for so many years.
Another positive point is that it does not have fixed measurements and it is possible to draw the desired size. Even though a small class is necessary to learn how to use it, it is not difficult to get the hang of it and soon everyone can do their tasks with it.
In addition, this is a very simple instrument to be found to buy and that depending on the model has very good values.
The only problem with this product is that when it is used by children it is necessary to pay attention, since it has a needle, which even without having a lot of points, can hurt.
What types of measures are there?
As much as everyone has a similar design, there are different compass models. The most common is the school , which is used by children and for simpler activities. It follows a standard model, with no variations.
Different from it is the precision compass , technical or baluster, which has a mechanism that contains a transverse rod connected to the tool shanks and helps to adjust and maintain the measurement more accurately.
There is also the cutting compass , which is widely used in crafts. It has a very different design from the other models and has a dry tip and another with a kind of blade, which can be used to cut fabrics, paper and even glass depending on the model.
Another model is the external compass . It consists of two rods with curved ends and serves to measure diameter, width, length and also for transferring measurements. With this same function, there is the internal compass , which differs from the external in that it has straight rods with a small curvature at the tip.
Digital compass or technical compass?
Like all other tools, the compass also gained its most technological version and thus the digital compass emerged.
It has a structure equal to that of technical bars, but it has on its top a display that shows the measurements in inches, fractions and millimeters.
This model can also be used to perform the common functions of measures, which are to draw circles and the like, but when solving geometric equations they do this almost automatically.
It is an instrument indicated for those who use this tool in a professional manner as architects, engineers and designers.
The big drawback about it is the price, since it usually costs much more than conventional models.
The price of the compass is very variable and depends on the type chosen. If you are looking for a school compass you can spend between R $ 4 up to about R $ 15.
Technical bars have a wide range of prices, and it is possible to find options with a value of around R $ 40 and others up to R $ 350.
Speaking of digital compass, the average price is R $ 400 and cut-offs vary between R $ 25 and R $ 400. The internal compass options cost around R $ 35 and the internal one costs R $ 12 until around R $ 100.
Did you know that using a hard graphite can result in a line with a very light outline, even applying a lot of pressure on the compass?
The ideal is to use a soft graphite and with a beveled tip, which generally makes a line more clear in an easy way.

Purchasing criteria: Factors for comparing time signature models
Faced with so many variations and options, even when choosing the simplest measure it can be tricky to define which is the most suitable for your type of use and it is to assist you that we have prepared a list below with the points you should take into consideration when comparing the models, they are:
- Maximum measure
- Type of use
Check now in detail to know how to make the best choice.
There are bars that have their structure produced in plastic or metal.
- Plastic : Normally the plastic options are more suitable for children and are the ones with the lowest price, but they are usually very fragile and have low durability.
- Metal : Metal ones are of superior quality and all technical bars are produced in this raw material. This is because their durability is longer, they are less fragile and tend to be more accurate.
The maximum circumference that a compass can reach is also variable among models and this is a factor that you should take into account.
There are options that can reach a maximum radius of 40 centimeters, while others only go up to 24 centimeters.
The size of the straight line changes in the same way and especially if you work using this tool you should take into consideration which measure will suit you best.
Type of use
This is another factor to be taken into account and it is directly related to the price you will spend on the bar.
If it is a compass for school use it is not worth buying a technical model because the activities done at school are very simple and do not require a more advanced tool.
Those who work in this area can invest in a more professional product and thanks to the large number of models it is possible not to spend a lot if you are not willing.
The digital is indicated even only for those who want more ease on a daily basis or to streamline the work, however it can be a good option.
Focusing more on technical bars, it is worth knowing that some come with accessories that can be very useful.
- Strip line : This is an accessory that works like a pen nib on which a little ink is deposited to trace the line.
- Tips : There are also different options of tips, there are adapters for pens and pencils, which do not always accompany all measures, types of graphites with different thicknesses and extension rods.
