The Mini Crawler PNT from Ratech Electronics is a self-propelled four-wheel-drive multi-conductor camera transporter. Its 12 super-bright LEDs with variable intensity control light the way through pipe 5 to 30 inches in diameter. The stainless steel tractor can be used for manhole-to-manhole or small-lateral pipe inspections, navigating through tight spaces. Using the full 360-degree-rotation pan-and-tilt camera, the user can see defects and obstructions more closely and in more detail. The power and controls to operate the crawler are in a handy remote control device. The unit comes with a manual lift and a conveniently built-in 512 Hz sonde for locating purposes. 800/461-9200; www.ratech-electronics.com.
