Attachment Tracking Made Easy

  • View the location of your attachments across multiple work sites in one dashboard

  • Track working hours per attachment to help predict the need for replacement wear parts or to replace the attachment itself
  • PL161 can be mounted to any asset brand or type
  • The PL161’s compact size allows you to collect data about your attachment without interfering with the work it is doing
  • View tracking through your smartphone with Cat App or on My.Cat.Com
  • View your attachments alongside your machines for full fleet management in VisionLink®

Rugged and Reliable

The PL161 is designed to be extremely rugged and maintenance-free to allow for installation in locations on assets that are exposed to harsh work environments. The device is battery powered for up to two years. The device’s firmware is pre-configured and installed. The PL161 communicates via Bluetooth® low energy technology in order to extend battery life.

PL161 is compatible with most smart devices that have Bluetooth 4.0 or later and is available for download from the App Store (iOS) or Google Play Store (Android).
