Free-pass Ruler / Dimension Ruler

Free-pass Ruler
Free-pass Ruler

The free-pass ruler has a transmitter and a receiver attached to it which allows you to measure through the obstacle without any problems. Therefore, a normal tapeline or laser ranger is not needed anymore. Attach the transmitter at the starting point of the measurement and put the receiver at the end of the measurement and it will give you accurate and exact length even if there are one or more obstacles.
