DeviHead

Head assembly core orientation tool

DeviHead

The DeviHead is an innovative, unique core orientation system incorporating a miniature survey instrument, making it small enough to fit inside a core barrel head assembly. Utilizing top quality electronic accelerometers for high accuracy survey data. DeviHead measures inclination, orientation, gravity vector, temperature, and battery status, and offers quality control on the results.

The DeviHead is a revolutionary system that can be fully integrated with your drilling equipment. Unlike other core orientation systems, core barrel adjustments are not necessary, and core orientation may be started or ended at any time without having to retrieve the drill string and core barrel from the drill hole.

The DeviHead replaces the inner tube cap and spindle of the core barrel head assembly already on site. It is designed to fit head assemblies from most of the major drilling tool manufacturers, without affecting length, operation, or quality.

Utilizing our innovative Brilliant Blue Technology (BBT) the DeviHead is quickly activated and communicates wirelessly with the handheld device, without the need for opening any threads. Ensuring quick set up, data transfer and download.

The operation follows a clear step-by-step procedure, and one probe can be started or downloaded while the other is down in the hole, fitting in with the drilling cycle to optimize drilling productivity.

Each kit includes two DeviHead units with interchangeable survey tools and spindle assemblies, ready to be used with the standard head assembly on site.
