Model 505 "Go-Fer" Pipe & Cable Locator by Tinker & Rasor

Radio Frequency Transmitter / Receiver for Pipeline Locating

Durable Construction

The "GO-FER" is housed in rugged, indestructible Cycolac cases and has injection-molded instrument panels for added strength. All electronic components are mounted on a single detachable circuit board for quick and easy maintenance. In addition, convenient battery access is made through removable doors on the transmitter and receiver. Both cases and circuitry are designed to tolerate the most extreme field temperatures, and make the "GO-FER" ideal for use in any environment.

Quartz Crystal Precision

The all new Detectron "GO-FER" locates buried metal structures with smooth accuracy and ease. Its quartz crystal controlled transmitter fine-tunes the signal for precise location every time. And when it comes to tracing distance, depth penetration, and sensitivity, the Model 505 rivals all other pipe and cable locators on the Market. The "GO-FER" can reach depths as great as 20 feet, and tracing distances of 1,000 feet are not uncommon


Improved Controls

The "GO-FER"s radio frequency receiver allows it to screen out distracting noise while it simultaneously detects cables and pipes with assured precision. The "GO-FER" is also the first locator of its kind to have a separate volume control for reducing signal loudness without sacrificing sensitivity. This feature enables quieter operation in enclosed areas where lower volume is desired. As in other Tinker & Rasor null-detecting locators, a null in the tone is detected as the pipe is crossed.
