- Active locating utilizes both the transmitter and the receiver. By applying a signal with the transmitter, the operator can trace the path of the utility with the receiver. Different utilities respond better to different frequencies, and the TW-8800 has three frequencies the operator can choose from: 82 kHz, 8.2 kHz, and 820 Hz.
- The passive locating method utilizes only the receiver. This method of locating uses signals that are inherently associated with the utility. The TW-8800 has two modes for passive locating: 50Hz/60Hz (power) and 14 kHz to 30 kHz (radio). The power mode senses the electromagnetic fields on energized electrical lines. The radio mode senses the re-radiated radio waves that are occasionally associated with utilities. Often these signals are weak, so to assist the operator, we added a feature that oscillates the signal, thus allowing the signal to be heard.
- Depth measurement to 16 ft. depending on conductor size, measurement mode, soil conditions. Automatic gain control for maximum sensitivity. Display gives intuitive 'left-right' signalling for accurate location of buried utilities.
- Designed for the most rugged field duty; weatherproof, durable. Made in the USA and comes with a two-year warranty.
- Tracing kit includes transmitter and receiver, ground rod, ground plate assembly and hard carrying case.
