BUILT FOR HDD CREWS

One locating language.
Five ways to work.

Every TerraPilot locator is built around a practical field workflow: scan the site, select the right transmitter frequency, match the locator, calibrate, and track the drill head with clear roll, pitch, depth and signal feedback.

01

Signal clarity

Choose frequencies for the conditions and use strong filtering to work through practical site interference.

02

Field control

Read roll, pitch, depth and signal strength in one workflow designed for efficient tracking.

03

Shared transmitters

TerraPilot 9, 7, 5 and 3 work with the shared ST, ET, S20 mini and S14 mini transmitter family. TerraPilot 50 uses its own integrated multi-frequency and Mini-Track transmitter family.
