Skytraxx Tweety-Pro használt

Mini vario with sensor fusion of pressure, acceleration, and gyro, so the instant vario reads sensitive. Two buttons to run it, 3 volume levels. Up to 150 hours on a single CR2450, which comes installed. Small and light enough for hike & fly, works as a first vario or a backup. Ships with the CR2450 already in, Velcro adhesive pads, a safety cord, and a quick start guide.
