Topcon RL-H4C Self-Leveling Rotary Laser 57177
The Topcon RL-H4C Self-Leveling Rotary Laser 57177 is accurate 1/16 inches at 100 feet, a range of up to 2,600 feet, and leveling within 5 degrees.  Its slope matching feature makes it an excellent tool for excavating. This self-leveling laser rotates at 600 RPM in full gear. If it is knocked out of position, it automatically re-levels itself with an outstanding accuracy of +/-10 arc seconds in angular measurements. The included laser receiver extends the range of this level to its full working range.  It is durable enough to withstand drops, and is both water and dust proof. The batteries provide up to 80 hours of continuous use and it automatically shuts off after 30 minutes of non-use.  There is a low battery indicator, and an out-of level alert that works on the 2-way communication system. It has fine and normal accuracy options, and 2 LCD displays - one on the front, the other on the rear.  Plus it comes with batteries and a rod clamp. Topcon's RL-H4C has convenient features like slope matching and high speed rotations. The new dual handle design makes this horizontal level easy to maneuver. This rugged construction laser has dry "D" batteries that provide up to 100 hours of use.  It is also weather-resist, being both dust-proof and resistant to water jets. The Topcon rotary laser also comes with a battery holder, a carrying case, user manual, and a 5 year limited warranty.
