V-Line Pro (Vesper)

Air Drones (UAV/UAS)

Description

The V-Line Pro is a tethered drone system compatible with Vesper Blue UAS drones, featuring a 25-meter (82 feet) tethered line and DC powered tether station that enables infinite flight times through hot swapping capabilities. The system includes the V-Assist mobile app for Android devices that provides real-time telemetry data and works as a floating app alongside other drone applications. It extends Vesper drone flight time to 7 hours on a single battery charge and supports single-operator use for public safety and emergency response missions.
