The Mini Crawler PNT from Ratech Electronics is a self-propelled, four-wheel-drive multiconductor camera transporter. The 12 super-bright LEDs with variable intensity 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 pan-and-tilt 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; www.ratech-electronics.com.
