| 1. Laser Levels | | | | |
| | | | This particular piece of surveying equipment |
| There are many different types of laser | | | | is most often used when new pipes, drains or |
| levels now being used in the construction | | | | sewers are being laid (installed). Once one |
| industry and depending upon the demands of | | | | section of the pipe has been laid the laser |

| which kind of level is used. But when it | | | | be aligned and graded in line with the one |
| comes to choosing a laser level do you choose | | | | already in place. Using this helps to ensure |
| one that is able to self level itself or one | | | | that the pipes being installed are done so |
| that you have to level manually. | | | | with a great deal more accuracy. |

| Certainly the biggest benefit to be gained | | | | 5. Laser Receivers |

| adjustments to it. Whilst as a manual one | | | | mentioned above) and is able to cover a much |

| used in order to measure as well as define | | | | is achieved the receiver will emit a constant |
