The GatorCam4 pipeline video inspection system from Radiodetection Corporation has a rugged controller with an integrated lithium-ion battery that removes the external power lead. A push-button fuel gauge provides a quick indication of remaining power even when the controller is switched off. It can be configured to suit most inspection requirements. A range of pushrods is available, from the extra-flexible 100-foot plumbers reel up to the 500-foot extra-stiff rod designed to push for longer distances. Both 1- and 2-inch cameras are available, which, when used with skids, can inspect pipes with diameters from 1 to 12 inches. 877/247-3797; www.radiodetection.com.
