Sonic is a mini-acoustic vario by Flytec for helmet or harness mounting. Small and effective! Ideal for coastal soaring, tandem and hike and fly, or as a back-up.

Sonic is a small "audio only" variometer (vario) designed for mounting on the helmet or harness with hook-and-loop fastener. Designed for pilots who want to enjoy freeflight with the minimum of technology. Small enough to tuck away in a harness pocket.
