Does I dig 2d have a laser receiver or do you use the laser to find datums for the idig
So with the Idig you can use it with or without the laser.
For instance you want to dig a foundation 500mm down from ground level, 0 the system on the ground you want to go down from, then dig down 500. Once you move back, zero it on the dug ground and it will keep this level right along.
Or using it with a laser, your laser is just a fixed reference point. Same job, you want to dig down 500mm and your laser is 1.2m above the finished level, type in 1.7m and of you go.... the laser is just a fixed reference point and you only need to catch it every time you move the machine.
The reason for this is that the system doesn't know if the machine has risen or dropped when you have moved, so when you catch the laser is then recalculates the difference.
