The RST Helix manhole inspection system from R.S. Technical Services can be deployed from a CCTV vehicle, pickup truck or ATV, and is capable of scanning a 10-foot manhole in under a minute. It has six high-resolution cameras that capture panoramic images of every surface, as well as six active 3-D sensors that record spatial data points for precision measurements. Once it reaches the bottom of a manhole, it returns and automatically transmits scan data to software where it can be reviewed in the office or in the field. 800/767-1974; www.rstechserv.com.
