The housing has a similar design to our normal High Flow Sonde Housing but is made from premium grade non magnetic stainless steels.
The housing needs to used with a non magnetic drill rod (sometimes called a collar) so the transmitter is well away from any magnetic interference than would upset it's "electronic compass".
These rods are normally 4.5m (15 ft) long. If the drilling job is in rock and a mud motor or tri-cone roller bit is being used then a second rod needs to be fitted to the front to ensure the steel in these components does not cause interference. For other ground conditions a non mag jetting assembly can be fitted or a non mag boring head with steering plate.
Our housing has a four part design to allow maximum flexibility to the user.
1) Rear Cap - attaches to the non mag rod and allows the transmitter to be removed.
2) Housing body - houses the transmitter in a protective capsule.
3) Indexing Sub - contains the indexing mechanism and connects to either another rod or
4) Boring Head and steering plate for drilling in soft ground. (This component is optional)
