Good work emits perfection. Imagine an unbalanced picture hanging on the wall. Doesn’t seem nice, does it? We like to see things in the level, balance in everything, a satisfactory shape in objects.

Not everything has a reference point with which you can straighten up designs and balance them. Torpedo level has successfully unraveled this problem in the case of non-linear objects. Torpedo levels are used to bring out a well-balanced and leveled structure both horizontally and vertically by the indication coming off from the liquid in the tube.


So, if you are looking for the best torpedo levels in the market, you have indeed come to the right place. All you need is PICK!

Torpedo Level buying guide

If there wasn’t need, there wouldn’t have been differences and superiority. The tool may be very simple to operate but not all model has your desired features. So, in order to buy a torpedo level, you must know what you will be getting and first of all you must know what you want and exactly what to look for.

That’s why we thought it would be better if we at first, take you through some delicate information that might help you to buy exactly what you need. Let’s go!


Vials in every torpedo level are not the same. So, you need to choose what you want for the vials. The material can be plastic, glass or acrylic. Among these three, we prefer glass. Because glass is tough and won’t leak, crack or fog over unlike others. There will be times when your torpedo level can fall from the surface. So, if you are looking for something durable glass would do a lot better compared to the others.

But also try to look for shockproof vials that will ensure that they don’t break from accidents or banging against anything. The vials are filled with diluted ethanol. The air bubble gives you the reading by moving per your adjustment. If you want a clear look at the readings even in the dark look for those which glow.

How many vials does your level feature? It’s important that it can’t be missed out. Two vials are the minimum requirements that measure horizontally and vertically simultaneously. These are often called plumb and level. They are able to measure 0 and 180 degrees and 90 degrees. But there are also vials for 30 and 45 degrees to give a more exact reading.


Torpedo levels mostly are designed and constructed to deal with arduous environments. Buy a tool that will serve you for a long period. So, testing the durability is really important. Try to look for the most durable material for the frame for your torpedo level.

The most common materials used in the torpedo level are ABS plastic and aluminum alloy. Both are comparatively lightweight for easy move around and portability. But there are differences. Such as plastic can be cast into any shape. Moreover, plastics are not affected by heat or cold depending on the temperature. But on the other hand, aluminum does not have a bit of edge like plastic. It conducts electricity which might be a danger in the case of the electric field. So, we advise you to look for a torpedo level that has plastic as a material.


Torpedo level with magnets featured is very much impressive. The magnetic system provides you a hands-free operation so that you have the luxury to focus on another thing at a time.

There are strip magnets and rare earth magnets. But in case of efficiency, the rare earth materials are comparatively more powerful than the strip magnets. Thus, it makes rare earth magnets a popular choice. But you don’t really need magnets if you are not working with metals. Magnets attract metallic dust when used in a workshop. So this indeed can create a problem ending in small shards scratching and damaging the surface. Also, do not forget to wipe away relics from a non-metal surface before getting started.


A V-groove is basically a concept to make way for the pipes and conduits to fit into places quickly and precisely. It’s very simple. A side of the torpedo level is designed like a V. More control is acquired by the material that fits into the groove. Though we only have been talking about pipes and conduits, these also do with any round shapes. It stabilizes the material and does the job effortlessly and gives you more fixity. V-groove is a must feature if you look forward to working with pipes and conduits.

Thumb Screw

Conduits require V-groove. But besides that, screw thumbs are also a part of the performance-enhancing. The thumbscrew fits the level to a piece of conduit to do good even in a bending situation. It comes in really handy for this specific job. If you are not into bending, then thumbscrews are not a necessary go feature. But what’s the problem if you get thumb screws even if you don’t need it. Then who knows when you are in need!

Accuracy level

You can never compromise with the accuracy level. The significant amount of maintaining straight lines and various angles require precise exactness. And that comes from a torpedo level which is made to assure success in projects.

Even a 0.01 inch of a failed measurement can ruin the entire structure. So, invest in one after a thorough test. Make certain the readings are right on the spot from the start.


In spite of obtaining the tool with great accuracy, the question remains. Can you read the machine clearly? 

Determining the level means able to grasp the extents despite its condition. The torpedo level’s contrast to the bubble or the size of the bubble could make a lot of difference.

Even the lighting situation can change the aspect of accurate reading. Always check the standards of visibility whenever you choose the particular item.

You are going to have to use it vertically or horizontally depending on your measuring project. This is why being able to read the bubble under any circumstance is of great importance.


Those with difficulty in reading traditional torpedo levels can move to digital ones if they want to avoid all the hassle.

Digital torpedo levels usually contain a screen that shows detailed measurements to almost every scale. It works exactly like a normal torpedo level with a little spice of digital tech.

So, if you have a knack of buying cool tech gadgets, you can choose this one for your works. Traditional or digital, they both are quite the same, to be honest.

Construction Material

You must be wondering how useful could this be; it is only a small level measuring tool! You will be mistaken if you think the materials do not matter. Because they do.

There are only two options, buy a cheap one that does not last long, get a quality grade level to pinpoint everything, and last more than expected. Easy as pie!

Think of the working environment. What if they are not always forgiving? What happens when the tool accidentally falls and breaks?

Sometimes getting durable things will require spending a little more than you want. But you will not be at a loss! A torpedo level must be able to withstand any pressure of tear or wear. 

The two most common materials used in the making are aluminum alloy and ABS plastic. Both are lightweight. However, aluminum could get hot or cold according to temperature.

Whereas plastic can mold into places that are hard to reach and will not be affected by a change of temperature. Electricians or mechanics need to consider this option carefully since plastics are nonconductive.

Even the color choice of color necessitates its value. A bright yellow, blue, or red could be easier to spot on a cluttered table. Saves a lot of time!


V-groove is a very important feature for those who have to work with pipes or conduits on a regular basis. You will see on one side of the level is shaped as V. This allows further stabilization on rounded materials.

Ease of Use

Most torpedo tool size ranges from 6 to 9 inches. The nature of your work ascertains the size of the torpedo level that entails. Go for a level that is easy to control and maneuver.

Do not forget to make lightweight a priority. Suppose the job involves cramped up space or unreachable spots. That is where a magnetic level would do the magic. The ease of operating it hands-free is beneficial in so many ways. 

A longer level is considered crucial for bigger construction purposes. But with a 6 or 7 inch, the level will perform an excellent job in any dimensional space.



It’s important to buy a tool with a warranty. The problem with torpedo levels is that the vials break or crack or leak the fluids out. So, try to look for the warranty that covers the vials. The best thing about the warranty is you get to know what it covers and whatnot. You never know what’s going to break. So, why not have a warranty and replace it or fix it without any expense!

What is a Torpedo Level

Before you get into the reviews, at first you should have an idea about what a torpedo level is. Basically, the torpedo level is a smaller version of a spirit level designed and made compact for easy use, portability, and convenience. You can use it in tight spaces and compare to large level contractors. These help you carry easily with you and do your work.

These tools are 5.5 to 10.3inches long but there are longer ones. Most of the two vials that measure 0 degrees and 90 degrees ensuring that you get the exact readings both horizontally and vertically. There are also levels that feature three or four vials to enhance performance. Technically, the 30 and 45-degree vials give you extended flexibility.

Do You Need a Torpedo Level?

At first, ask yourself do you want a picture on your wall hanging in a lopsided position? (just a simple example) If not then yes you do need a torpedo level. To make it more simple a torpedo level is like a fire extinguisher, you don’t really know until you need it.

For carpenters, electricians, and plumbers it is a necessary evil. Torpedo level has several uses. Used to put up a shelf for your books or a picture of your family o the wall. If you want flat-pack furniture, it is necessary to pick. Despite the fact, the contractors need larger spirit levels for their use but it comes in handy in tight spaces and these are not also too expensive.

How to Use a Torpedo Level

Before getting started, you need to clean the level and remove all dirt from the edges. Choose your surface and place the level on the object. The spirit tube must run parallel to the object. You will see the bubble floating to the top of the spirit tube. Focus at the level of the spirit tube.

Observe where the bubble is inside the spirit tube. If it is in the center between the lines on the tube, the object is level. If the bubble is on the right side of the lines, the object is said to be downward from right to left. If the bubble is on the left side of the lines, the object is said to be downward from left to right.

In order to find the true value for vertical, just repeat the same process but vertically.


Place the torpedo level on a flat and roughly level surface. See the bubble inside the tube and note down the readings. This reading refers to what extent the surface is parallel to the horizontal plane and the accuracy is yet unknown. Do a 180-degrees rotation and repeat the same procedure. If the readings in both events are the same then your level has high accuracy if not then not so accurate.

Spirit Level vs Torpedo Level

A spirit level indicates whether a surface is horizontal (level) or vertical (plumb). The carpenters, stonemasons, bricklayers, other building trades workers, surveyors, millwrights, and other metalworkers use different types of spirit levels. A device that consists of a sealed glass tube filled with liquid containing an air bubble which indicates the level by its position.

A torpedo level is a spirit level designed for use in tight spaces. Torpedo levels are small in size. It consists of two or three vials filled with ethanol. Some features glow in the dark visibility. The torpedo level also indicates the level by the position of the bubble.


What Is a Torpedo Level For?

A torpedo level is a type of spirit level that is an essential tool for any professional working in tight spaces. The body of the level is made of either metal or plastic and contains two or three tube vials. These tubes, or vials, contain yellowish-green additives and are used to determine the surface level.

Are Goldblatt Levels Good?

What Length Level Should I Buy?

Most Pros start with a 48″ level for general work or a torpedo level for plumbers and electricians. Each job is different, and you’ll notice that the more specific the job, the more specific the level lengths veterans will carry.

Q: Which one should I buy?

Ans:  It depends on what you work with. Two vials would serve you great, thumb screws are not necessary if you are only a frequent user.

Q: What are the numbers under the line?

Ans: Those are the multipliers you need to use for specific angles.

Q: Which one I should prefer, Glass or plastic?

Ans: Glass is a better option if you think about shock damaging and durability.

Q: Are longer levels more accurate?

Ans: Technically yes. A longer level provides better accuracy. Nevertheless, it would be useless when appointing in compact quarters. A practical of 7 or 9 inches is a good idea for all-purpose.

Q: What is a surface level?

Ans: A surface level is commonly applied to see if the camper vehicle is leveled on ground. It measures the 360 degrees of level in a circular vial as you lay it flat. 

Q: How do I know if the spirit level is accurate?

Ans: Best method is to check repeatedly on a flat wall vertically. Take note of where the bubble position is. If it is consistent to appear between the lines, you are good to go.

Similarly, you can try it on horizontal surfaces like flooring areas.

Q: Why is it called spirit level?

Ans: The bubble level is, at times, referred to as spirit level due to the mineral inside the vial. This liquidated substance is resistant to UV, fade-outs, and discoloring.
