28X vs 36X Auto Level Myzox CL-28 or CL-36 for Surveying Malaysia
28X vs 36X Auto Level Myzox CL-28 or CL-36 for Surveying Malaysia
When choosing an automatic level, one specification that buyers often notice first is telescope magnification.
The Myzox CL-28 provides 28X magnification, while the Myzox CL-36 provides 36X magnification. But does higher magnification automatically mean a better auto level?
Not necessarily. The right choice depends on working distance, required leveling accuracy and the type of construction or surveying work being performed.
MTM Precision Sdn. Bhd. is an authorized distributor of Myzox in Malaysia, supplying professional Myzox surveying instruments and accessories.
What Does 28X Magnification Mean?
A 28X telescope makes the observed target appear approximately 28 times larger in angular size than it would to the unaided eye.
For an auto level, this helps the operator see graduations on a leveling staff at normal construction-site working distances.
The Myzox CL-28 is therefore suitable for many routine applications such as:
Building construction
Foundation leveling
Finished floor level checking
Drainage work
Earthworks
Landscaping
Benchmark transfer
General site leveling
For contractors mainly working on building sites, 28X magnification can be a practical general-purpose specification.
What Does 36X Magnification Mean?
The Myzox CL-36 increases telescope magnification to 36X.
Higher magnification makes the leveling staff appear larger through the telescope, which can be beneficial when working at longer observation distances.
Applications where this may be useful include:
Road construction
Infrastructure projects
Large civil engineering sites
Long-distance leveling
Industrial development
Engineering surveying
Benchmark transfer across larger sites
Does 36X Mean the CL-36 Is More Accurate?
Magnification and leveling accuracy are different specifications.
However, in this particular Myzox CL series, the CL-36 also has the higher specified leveling accuracy.
Myzox CL-28:
28X magnification
±2.0 mm accuracy for 1 km double-run leveling
Myzox CL-36:
36X magnification
±1.0 mm accuracy for 1 km double-run leveling
Therefore, the CL-36 provides both higher magnification and a higher leveling accuracy specification.

The two models share several important specifications, making magnification and leveling accuracy the key considerations when selecting between them.
Is 28X Enough for Construction Work?
For many construction applications, yes.
A contractor working on building projects may typically use an auto level for:
Checking excavation depth
Establishing foundation levels
Checking concrete elevations
Transferring benchmarks
Establishing finished floor levels
Checking external ground levels
If these observations are made at normal working distances and the CL-28's specified accuracy meets the project requirements, 28X may be sufficient.
When Is 36X More Useful?
Consider 36X magnification when:
The construction site is large
Longer sight distances are common
Leveling staff graduations need greater visual magnification
Road or infrastructure work is involved
Higher specified leveling accuracy is required
This does not mean operators should intentionally use excessively long sight distances. Good leveling practice and project procedures remain important.
Does Higher Magnification Have Any Limitations?
Higher magnification does not eliminate environmental effects.
At long distances, observations may still be influenced by:
Heat shimmer
Atmospheric turbulence
Poor visibility
Strong sunlight
Staff movement
Ground vibration
This is particularly relevant in Malaysia, where strong daytime heating can affect optical observations over hot surfaces.
Higher magnification should therefore be viewed as one part of the overall measurement system.
Which Is Better for Building Contractors?
For general building construction, the Myzox CL-28 is likely to meet many routine leveling requirements.
Its 28X magnification provides a practical balance for common site work.
Typical applications include:
Residential construction
Commercial buildings
Foundation work
Concrete slabs
Drainage
Landscaping
Which Is Better for Civil Engineering?
Civil engineering projects often involve larger sites and longer working distances.
For applications such as:
Road construction
Highway projects
Large drainage systems
Infrastructure development
Industrial projects
Large earthworks
the Myzox CL-36 may offer an advantage because of its 36X magnification and ±1.0 mm leveling specification.
Which Is Better for Surveyors?
Professional surveyors should select the instrument according to the accuracy requirements of the work.
For routine leveling, the CL-28 may be adequate.
For applications where higher optical magnification and a higher specified leveling accuracy are valuable, the CL-36 is the stronger option.
Should I Buy Based Only on Magnification?
No.
Before buying an auto level, consider:
Required leveling accuracy
Typical sight distance
Type of project
Frequency of use
Site conditions
Surveying procedures
Available accessories
After-sales support
The best auto level is the model that matches the actual requirements of your work.
Frequently Asked Questions
Is 36X better than 28X for an auto level?
36X provides greater magnification, but whether it is better depends on your application. Many routine construction jobs can be performed with 28X.
What is the magnification of the Myzox CL-28?
The CL-28 provides 28X magnification.
What is the magnification of the Myzox CL-36?
The CL-36 provides 36X magnification.
Which model has better leveling accuracy?
The CL-36 has the higher specified accuracy at ±1.0 mm for 1 km double-run leveling, compared with ±2.0 mm for the CL-28.
Which model should a building contractor choose?
For general construction, the CL-28 can be a practical choice. If higher magnification or greater specified accuracy is required, consider the CL-36.
Which model is suitable for road construction?
Both can be used depending on project requirements, but the CL-36's higher magnification may be particularly useful for larger road and infrastructure sites.
