Tilt Surveying

The Hemisphere C631 finally allows for tilt shots while surveying, up to an angle of 60°. With a 60° internal tilt sensor, you can get shots you thought were otherwise impossible. Whether the point is under a vehicle or directly next to a building, you can tilt the receiver to an angle where it can see more of the sky, ensuring your accuracy. The internal tilt sensor in the C631 offers 2 cm of compensation at 30° or 5 cm at 60°. Never have the calibration of your pole impact your results again.

Designed Around Surveying

The Hemisphere C631 is designed to make surveying easy. With the internal cell modem and powerful 1 Watt internal radio, the C631 is designed to give you the flexibility to work around your projects.

With the hot swappable batteries, there is no need to stop in the middle of the day and reconfigure your base and rover as the batteries die. Simply keep an extra set of batteries on hand and keep working as long as you need. Not that you should ever have to swap batteries as the C631 can run for 9 hours off a single set of batteries. This is the receiver that works as long as you do. The entire receiver is protected by a magnesium alloy enclosure that is rated for a 2 m pole drop, and is completely dust and waterproof.
