There is a debate regarding which camera is better for main line sewer inspection: Ridgid or Spartan, or I would say between Ridgid or the other cameras. How probably has been seen on the picture I chose RIDGID. Easy to work in crawl spaces, hard access, easy to operate. The locator is very precisely, but gave some error when sewer is deeper than 7 feet and under the concrete path. Overall RIDGID camera is the best on the market.
