The Toughest, Most Versatile Housing Available.

Only Radius combines the strength and protection of an end-load housing with the convenience of a side-load unit. While other side-load housings were designed for dirt drilling, our patented rock housing was specifically designed for drilling rock. Only Radius rock housings give you:

Enhanced Sonde Protection:

With our recessed cavity design, the sonde is secured into the body of the housing and locked in place. Rubber o-rings minimize vibration and protect the beacon inside the cavity.

Rock-Solid Durability:

Our patented smaller cavity opening can withstand the heavy torque and flex loads that are generated when using rock bits. While others use a hollowed-out design, Radius rock housings have a solid ?” door ? the thickest in the industry.

Extraordinary Flexibility:

Radius housings are the only side-loads to accept all electronics including Digitrak® 15” sonde and 19” deep sonde, Subsite® 86” series beacons as well as wire-line systems and high-flow models. Non-magnetic housings are also available for geo-navigation systems.
