It is difficult for you to find the range measurement from wall to wall with biggest range. Traditionally people are measuring by a tape or any measurement tool. Now you will get the range measurement just a second. Powerfull, efficient and accurately. It will save much of your time.
Bosch has come out with Digital Laser Rangefinder Kit (DLR). The Bosch DLR165K is also a lot cheaper then most other DLR’s because it is capable of about half the distance range. Come out with 4″ pocket size. Small and really usefull. This for most people is a great thing, because who really needs to measure more then 165 feet? If you do need more distance, you are looking to pay about double the price, for double the distance. Tom Smith Development have been using this tool for their measurement assistance.
