[Southsider]

Has anyone else worked with the CST Berger transit/levels and had problems with calibration?

Yes and I have had my laser level since 2001 and I just sent it in for a service and it has definitely paid for itself thru the time it saved me and keeping everything accurate. I just bought a cheap laser from home depot for $70 that does something similar and it worked out fine. I was out of state doing a siding job. I think there a must for contractors
