The Sonic mini vario is an “audio only” helmet-mounted variometer especially designed for the pilots who want a minimum of technology (and for pilots that want a reliable back-up instrument for cross country and competition flying). The Sonic is also great for coastal soaring, where an altitude indication is of little importance.
