Leica MC200 Depth Master Digging System 

The Leica Depth Master MC 200 is designed for digging applications where only indicate control is required.  The ME200 works with most all rotary lasers.

In general, the rotary construction lasers on the market today are not all the same when it comes to accuracy.

The Dot Laser

A dot laser emits only a laser dot.  Usually a dot laser has a plumb down, plumb up and a
horizontal doe at 90º to plumb up and down.  

Dot, Line & Rotary Laser Levels

It is well known to any laser level contractor that there are varieties of laser leveling
tools available on the market.  

Laser Reference Alpha- C Cone Laser

The ProShot Alpha – C Cone Laser has the same durability and performance of the standard Alpha Laser.
The standard Alpha Laser has always had a great reputation for quality and dependability at a value price.

Leica Lino L2P5G Laser

The Leica Lino L2P5G uses the best green laser technology and combines it with functionalities of a cross line laser and a point laser.  It’s green laser beams and points are up to four times more visible to the human eye compared to red lasers, which makes it the ideal tool for bright environments and large rooms.

The Leica Rugby 640G construction laser is the perfect instrument for all contractors who need to level, align and square indoors or outdoors.  The Rugby 640G is a green beam laser at an affordable price.

Laser Distance Measuring Tools or Electronic Tape Measures off true laser light (not sound) for the most accurate measuring.  You simply point the laser distance measuring device's dot at a target like a wall, building, utility pole or nearly any object and the device will show the distance units LCD screen.  These measuring devices are true time savers and are very accurate at the same time.

Slope can be calculated as a percentage which is calculated in much the same way as the gradient.  Rise over run equals % of slope.  

Maybe you're wanting to figure the slope of a driveway, a sanitary or storm sewer pipe, a parking lot, a handicap accessible ramp or the slope of a drainage ditch?  Some people use the term slope (degree of angle) and people use percent.
