The LT400HS is a rugged 120-channel GPS+GLONASS handheld receiver designed to achieve sub-meter to RTK centimeter accuracy in adverse mapping conditions. The LT400HS is the most cost-effective and powerful GNSS Solution for survey, construction and GIS professionals.
The LT400HS is the perfect choice for companies which have not yet invested in GNSS technology due to cost or/and occasional equipment use (earth moving and landscape contractors, real estate developers, construction SMEs, agriculture irrigation, utilities mapping..).
Combined with DigiTerra Explorer Mobile GIS software, the LT400HS GNSS handheld offers feature-rich solution for accurate GIS field data collection and maintenance.
