I have not seen that one but it looks like just a straight shot not a rotating one.
The one I have is sold at Lowes and is a rotary self leveling one. We use it all the time from marking where to cut posts when building a deck, marking around a whole hose thats been added on to 4 or 5 times to mark the starting point for siding so as we work around the house the outside corners line up, to marking a line for setting chair railing. We work mostly in 100 plus year old houses where nothings ever level of flat so it's been a joy to use.
There so simple most people would not even need the directions.
