Level Up with Johnson
This pocket-sized sight level is an indispensable tool for spot checks of level references across your jobsite. Operation is simple – just hold the level to your eye and look through it. A mirror will allow you to see both the internal bubble vial (which ensures you are holding it level) and a non-magnified view to the outside world with a level indicator - so you can sight directly on your target.
Ideal for surveyors, plumbers, general contractors & excavators
Sight through the level at a grade rod or other target. Look through the scope, find level, then read the grade rod where it crosses the level indicator in the sight level. You've found level. Now, compare this reading to the height of your eyeball, divide by the distance between you and the grade rod, and you can easily calculate the grade between any two points. It couldn't be simpler!
Note: This sight level has no image magnification. If you need to sight longer distances or perform more complicated layout work, consider a builder’s level, transit level, or theodolite. See the chart below for all Johnson Optical options!
