The Model 505 GO-FER split-box locator from Tinker & Rasor locates buried metal structures with smooth accuracy and ease. Its quartz crystal controlled transmitter fine tunes the signal for precise location. It can reach depths as great as 20 feet and tracing distances of 1,000 feet are not uncommon. Its radio frequency receiver allows it to screen out distracting noise while it simultaneously detects cables and pipes with assured precision. It has a separate volume control for reducing signal loudness without sacrificing sensitivity, enabling quieter operation in enclosed areas where lower volume is desired. 909/890-0700; www.detectron.com
