Easy installations

With an operational tilt range of ± 90°, the hole required for direct burial just got a lot smaller.

And, if you need to be up and running in the shortest timeframe, the long-period corner can be adjusted pre- or post-deployment* allowing you to match the response to the environment.

* when operated with a Minimus digitiser
