Are cheap laser levels any good?

Laser levels are commonly used in construction, woodworking, and home improvement projects to create straight, level lines across a surface. In this article, we will discuss the suitability of cheaper laser levels, the factors to consider when selecting a laser level, and when choosing a cheaper or more expensive option is appropriate.

The Pros Of Cheap Laser Levels

Cheap laser levels are significantly cheaper than their expensive counterparts, making them a cost-effective option for small home improvement projects or DIY tasks. They are lightweight, portable, and battery-powered, making them convenient for outdoor use where power sources may be limited.

The Cons Of Cheap Laser Levels (Limited Accuracy Range )

For the user, the limited accuracy and durability of cheap laser levels are their most obvious drawbacks. It will limit their usefulness in larger-scale projects or professional construction work.

Such as,

1. Due to the imperfect design and process of cheap laser level, the brightness will be significantly reduced when used for a long distance, the light will scatter, the line width will change, and the accuracy will be wrong.
2. Continuous use will cause the machine to heat up or under the hot working environment, affecting accuracy.
3. After an accident falls or is in alarm mode, there will also be accuracy problems.
4. The battery and power supply method design defects lead to too short working time, affecting normal use and so on.

Comparing Cheap And Expensive Laser Levels

When comparing cheap and expensive laser levels, there are several key differences in accuracy, range, and durability. These differences can significantly impact the cost-benefit analysis of choosing a cheaper or more expensive option.

Accuracy: Expensive laser levels typically offer higher accuracy than their cheaper counterparts. Cheaper laser levels may have a deviation of up to 1/8 inch per 33 feet, while expensive models may have a deviation of less than ±1/13 inch per 33 feet.

Range: The range of a laser level is another important factor to consider. Expensive laser levels can project a laser beam over a greater distance than cheaper models. For instance, while a cheap laser level may range up to 30 feet or more but can't keep high accuracy, an expensive model can project a beam over several hundred feet and keep high accuracy.

For example, Dovoh green line laser levels' working range (300LUX) is 20m/ 66ft. The working range can be extended to 60m/ 197ft under pulse mode with a laser receiver(the receiver is not included in the packing list). And it still can keep the accuracy.

Durability: Expensive laser levels are often more durable than cheaper models. They are made with high-quality materials and unique designs. It can withstand rough handling and exposure to harsh weather conditions. On the other hand, cheaper laser levels are often made with plastic components and imperfect designs that may not be as durable.  

As we know, accuracy is so important to the laser level. Then how to check a laser level for accuracy？

Conclusion

In conclusion, while cheap laser levels may be suitable for small-scale DIY projects or occasional use, they come with accuracy, range, and durability limitations. The brightness, line width, and accuracy of cheap laser levels may be compromised when used over long distances or in hot environments. Battery capacity can't keep up, affecting normal use. In comparison, expensive laser levels offer higher accuracy, longer range, and greater durability due to their higher-quality materials and construction. An expensive laser level may be a more prudent choice for professional construction workers or larger-scale projects.  

And one tip for choosing a laser level is to consider the warranty period. The warranty period is crucial in ensuring a laser level's quality, durability, and reliability, as it assures the manufacturer's confidence in the product and protection against potential defects or issues.
