The 200-foot pushrod capability of the PortaVision 3 from HammerHead Trenchless Equipment can be increased from its standard system to a 300- or 400-foot capability simply by changing out its fiberglass spiral-wound pushrod reels, eliminating the cost of duplicate system components. The fiberglass spiral-wound material used to make the pushrod lasts up to four times longer than less durable pushrod materials. Wheeled camera skids are available for use with 8- to 12-inch pipe diameters. 800/331-6653; www.hydraliner.com.
