Topcon GR-3 GPS Receiver

GR3 is a GPS receiver used

 by surveyors to establish an exact position on earth down to one millimeter, by tracking up to 36 satellites simultaneously. Its unique shape and component architecture offers many advantages: Two battery packs nest into an I-beam shaped magnesium chassis. These batteries are oriented vertically to provide a handle, but also to keep the center of gravity as close to the range pole axis as possible to provide good balance. The top is square so it won’t roll if leaned against a wall. GR3 is completely waterproof to withstand extreme weather conditions. The top bumper even overlaps the base so rainwater runs off the unit, keeping the controls and handle dry.
