The Ratech Mini Crawler PNT is a self-propelled four-wheel-drive multiconductor camera transporter. The 12 super-bright LEDs with variable light intensity control light the way through 5- to 30-inch-diameter pipes. Using the full 360-degree-rotation pan-and-tilt camera, users will be able to see defects and obstructions more closely and in more detail. This same camera head is interchangeable with the head on the company’s push camera system. The power and controls to operate the crawler are in a handy remote control device. It comes with a manual lift and built-in 512 Hz sonde for locating purposes. 800/461-9200;
