Product Code: CHC i80 GNSS Receiver

Light And Ultra Rugged Eliminates User Fatigue




The i80 represents the pinnacle of productivity on today’s jobsite. Leading technology with superior capabilities, the i80 has tracks all five constellations, ten frequencies, and uses every connectivity method available. The i80 is the smallest receiver on the market incorporating dual hot swappable batteries, allowing continuous uninterrupted work. All these features integrated into a small ergonomic package results in the most productive day of surveying possible.


▪  Light & ultra-rugged eliminates user fatigue
▪  Tilt & azimuth allow for more shots to be collected using RTK
▪  Advanced connectivity integrates into any process with nearly any hardware
▪  Common work flows without a data collector
▪  Future proof design for years of productivity
