TRAXALL is CDI’s major advance in state-of-the-art pipeline pig location and tracking. Building on 25 years of tracking know-how and our sophisticated new Digital Signal Processing (DSP) technology, the 770 tracks 22 Hz and as many as 7 additional transmitter frequencies simultaneously with a unique color assignment for each on the bright, wide temperature display.

CDI’s new Pinpointer user interface technology allows for easy pig location to within inches without the need for tricky nulling procedures.


For users that don’t feel that they need the full capability of tracking 8 transmitter frequencies simultaneously, the TRAXALL 720 offers every feature from the TRAXALL 770 but has a lower price point and tracks fewer frequencies – 3 instead of 8.


Passage detection, Pinpointing, and launch/receive verification of MFL inspection tools is a breeze with TRAXALL 770/720 advanced permanent magnet tracking and locating capabilities. The system’s graphical user interface for MFL shows familiar zero-crossing signals with full Pinpointing, recording and passage monitoring.


TRAXALL 770 and 720 are equipped with a high speed GPS systems allowing arbitrary points of interest to be Waypointed and stored in memory as GPS coordinates. Trackpointing records breadcrumb trails showing routes taken to and from hard-to-find locations. Returning to a pig’s Waypoint location or retracing your path along a pipeline with Trackpoints is a snap with the TRAXALL system’s robust, built-in Navigate to Waypoint capabilities. Waypoint and Trackpoints may also be downloaded and viewed with Google Maps for desktop PC viewing of navigation data. TRAXALL’s GPS system even provides automatic clock setting with high precision and stability.

Bluetooth and Satellite Notification

The system’s Bluetooth wireless feature allows downloading of recorded passages, Waypoints, Trackpoints, and remote viewing of the system from a vehicle in inclement weather. As another industry first, the TRAXALL systems may be equipped with a CDI LineStat radio system. LineStat provides the ability to autonomously monitor for pig passages and send remote notifications as emails or text messages. LineStat requires no cellular telephone network and functions anywhere in the world.


CDI has developed a very large variety of transmitters of various sizes (including ATEX certified versions) to work with our TRAXALL 720 and TRAXALL 770 receivers. These transmitters are user-programmable to operate at industry-standard 22Hz or TRAXALL-specific frequencies.
