Product Description

The Topcon GR-3 unit is rugged GPS receiver uses 36 satellites to give you the geographical coordinates down to the last millimeter. It will also allow you to locate reference points with a high degree of precision.

The GPS receiver is easy to hold due to the dual hot-swappable batteries. For balancing, the 2 batteries are oriented vertically to keep the center of gravity close to the range pole axis. The device is shock- proofed, so it can "easily" handle frontal cliff impacts (but don't try it on purpose, though). The main housing is is an I-beam shaped rugged magnesium, engineered to resist a fall from a range pole. It's weather proof too: the micro-tuned antenna, the switches and the connectors are housed under a plastic and rubber dome which overlaps the base and battery handle.
