Scottsdale, AZ — August 23, 2010 — (TSX: HEM) Hemisphere GPS announces the release of the Earthworks X300 excavator guidance system. Integrating Hemisphere GPS’ patented Crescent Vector GPS compass technology X300 measures and displays three-dimensional excavator positioning to operators, vastly improving excavation proficiency and accuracy and greatly reducing rework.

Following the successful release of the X200 full two-dimensional machine guidance system in March of this year, X300 provides real-time three-dimensional visual feedback to the operator on the position of the bucket teeth relative to a design grade surface. X300 will also function in a full two-dimensional mode when jobs do not require a three-dimensional design file. ‘Design Grade on site’ features offered through the touch screen interface conveniently guide the operator through two-dimensional jobs. Even the smallest contractor will realize the benefits of higher productivity, increased safety, and a quick return on investment.

“X300 reduces the need for survey staking and manual grade-checking, which leads to greater efficiency, lower cost, and improved safety,” says John Bohlke, General Manager of Earthworks at Hemisphere GPS. “The operator can remain in the cab making the best use of the operating hours.”

X300 ensures improved productivity, accuracy, and job execution flexibility through a combination of ultra-rugged tilt sensors, GPS systems, three-dimensional design file, and an operator touch screen display. X300 is ideal for both coarse and fine-grade excavation applications including site preparation and general earthwork, road construction, mining, utility trenching, complex grading, and marine dredging. X300 is the excavator guidance tool that allows for more competitive bids, instills confidence in project status and completion accuracy, and nets significant enhanced profitability.

Hemisphere GPS has adapted its proven machine control technology and fit for purpose solutions business model currently used in agriculture, aerial application, marine, and survey markets to meet the needs of the construction industry.

Hemisphere GPS is in the process of signing Earthworks dealer agreements in the US and Canada and is currently seeking additional product dealers. The company also plans to expand its Earthworks product portfolio by offering complementary excavator and blade solutions throughout 2010.
