The DT340 Pipe Crawler from Deep Trekker is completely self-contained in two carrying cases, requiring no dedicated service truck to operate. It can be operated in difficult environments, with anodized die-cast aluminum body and magnetically coupled wheel drives that require no maintenance. The optional track system is made from steel cord-reinforced polyurethane, ready to maneuver over tough obstacles. It is battery powered, with rechargeable lithium-ion batteries contained within the system. This means the unit can be deployed from anywhere. The batteries last between six and eight hours on a single 1.5-hour charge. It can operate both in dry and wet pipes, and is submersible up to 164 feet. 519/342-3177; www.deeptrekker.com.
