http://www.AsktheBuilder.com founder, Tim Carter, demonstrates how to get things level while building a shed using a modern laser level and a traditional optical builder's transit.
Both the laser level and transit are great tools. The advantage of the laser is that it requires only one person to operate it.
The optical transit requires two people - one at the transit and one holding the grade pole.
