  • Each LFET pod is mounted to a specially designed sled that can be pulled or pushed through the penstock by the Viper
  • Provides a scan width of 16” across the bottom of the penstock
  • With 300’ of cabling it is able to scan 250’ lengths while also being able to traverse inside diameter transitions
