- Grading contractors and land surveyors also use the hand level as a tool.
- To find a height or horizontal space, a hand level compares several points to a reference point.
- For preliminary land survey jobs, basic distance measuring, or any other site task, hand-level surveying is perfect.
- Since it does not need a tripod stand or levelling instrument rig, hand-level surveying saves us time.
- Contractors also use hand-level surveying because it is a fast operation.
Sight level, pocket level, and Abney level are all terms used to describe hand level.
What Is Site Level?
The bare minimum you’ll need to competently plan a construction design on a property is site levels. We recommend that you have these before you start writing (or mouse to mouse pad). It will save you a lot of time later.
This method is suitable for a construction site or one that needs to be cleaned of all structures in preparation for a new creation.
They help you predict the height of a building on ground levels and recession jets, and they’re also useful if the council has set a minimum floor level. They’re also good for draining stormwater to the road’s edge.

What Is Hand Level?
When levelling, a hand level is a small levelling device that is kept in hand. It is made up of a 100 to the 150-mm-long rectangular tube.
A hand level (also known as a light level or hand sight level) is an instrument used
for estimating rather than precision levelling. Within a telescope, a hand level is basically a spirit level. Grading contractors and land surveyors often use the instrument to equate several points to a reference point to obtain approximations of level or distance.
When opposed to putting up a tripod and levelling instrument, hand levels save time. The trade-off is that, while hand levels take much less time to set up, they are much less precise than precision instruments.
Sight ranges are useful for preliminary surveying and determining distances.
Bricklaying, fencing, and laying a lawn are examples of projects where hand-sight levels are desirable. Using a hand sight level may help most DIY projects around the house that need some level of estimation.

Estimating Distances with a Sight Level
A sight level, as well as a sighting rod, could also be used to estimate distances between both the user and also another object.
Start by taking a look around the unit. The lines at the high and low ends of the viewing window are worth noting. The difference between the bottom and the top is usually 1:12.
The customer is 36 feet away from its rod unless the top line is at 6 feet, as well as the bottom line is now at 3 feet, as seen from the range angle.
So this is how it works in mathematics. First, describe the difference in the viewing window seen between two distances: 6 – 3 means 3. To transform from the distance proportional to the real distance, compare the difference and measure it by 12: 36 = 3 x 12
A hand level, also recognized as a hand sight level or a sight level, is a hand-held optical instrument with a spirit level integrated into a telescope.
