The 4 kHz locate frequency is designed for tracing high-impedance lines such as twisted pair telecoms or street lighting.  Since such utilities are often found in areas of dense infrastructure, you can combine 4 kHz with CD to ensure you follow the right line. 

The MRX SG is effective for locating a wide variety of underground utilities and offers seven active antenna modes, including:

Peak+ which combines the accuracy of the Peak bargraph with Null arrows, which can indicate the presence of distortion.

Guidance, for rapidly tracing the general path of a buried utility.

Broad peak, can be used to detect and trace very weak signals, for example very deep utilities.

With 21 active locate frequencies spanning from ELF to 200kHz, the MRX SG provides a comprehensive range of frequencies for underground utility location. The available frequencies include a wide range of low, mid, and high frequencies to accommodate various terrains and utilities.

Locate and mapping professionals can optimise their MRX SG for their unique locating challenges by selecting up to 5 custom frequencies between 50Hz and 1kHz, adjustable with 1Hz precision.

This MRX SG supports four distinct sonde frequencies: 512Hz, 640Hz, 8kHz, and 33kHz. This range of frequencies allows for optimal performance in various locating scenarios.

The MRX SG offers five passive locating modes for detecting existing signals without transmitting a signal: Power, Radio, CPS (Cathodic Protection System), CATV (Cable TV), and a Passive Avoidance mode for simultaneous power and radio detection. 

Current Direction is a powerful tool that augments the capabilities of pipe and cable locators to help operators pick out their target line from others nearby. Using fundamental properties of electromagnetism, CD allows you to locate your utility quickly and eliminate wasted time following false trails.

Up to 5 additional frequencies can be programmed into the MRX G & MRX SG locators to match them to the signals found on your target networks. 

When a signal transmitter can’t be connected, tracing individual underground power lines through complex networks can be a real challenge: conflicting or powerful signals can confuse the operator, or combine to create a broad wash of signal. 

With a single key press, you can now utilize the harmonic properties of power signals to establish if a signal comes from one source or multiple cables, then trace and mark their routes.

Combine the MRX with an A-frame accessory to identify and pinpoint insulation sheath faults to within 4" (10cm).

iLOC is an advanced Bluetooth® link between the locator and transmitter, which allows you to control the locate signal’s power and frequency from up to 1400’ / 450m away. Less time walking and more time locating.
