Anyone own an elevator tripod for your laser level? I am thinking about purchasing one. The elevator tripod would allow me to 'dial in' the same benchmark elevations on paver, bluestone, and wall jobs. I could write the benchmark elevations on the design (and the finish elevations) and not have to change or re-write the numbers everyday on the same job. I have seen the prices varying from $150.00 over $400.00. Amazon sells the Stabila, but it doesn't get good reviews. I would like to hear your experience with these tripods- if anyone is using them!
