The Blue Vigil RS1000 Ground Tether System features a 50m (164ft) tether cable that will power your DJI drone for the entirety of your mission, eliminating the need to land and swap batteries. The system automatically manages the tension of the tether cable which allows for a safe flying experience. This system is designed for use with the DJI Inspire 1, Inspire 2, and Matrice 200 series drones. In order to use the RS1000 with your drone, you will need the right accessory kits, which are sold separately. Please call 800-359-0530 if you need assistance ordering your drone tether system.
