E90 RTK GNSS
The GNSS RTK E90 is equipped with wifi and NFC connectivity for flexible connection of other peripherals.
All new CHCNav brand GNSS RTK models are equipped with multi-channel connectivity in addition to Bluetooth as the regular E90 models are equipped with NFC and wifi connectivity. makes it possible to connect additional peripheral devices such as handheld rangefinders, reverb depth meters without having to plug in wires like before.
The multi-connection feature allows the CHC E90 GNSS receiver to be connected to the rangefinder to measure the intersection in the corners of the house without having to place the unit directly on the measuring point.
