Brauniger IQ Sonic is an audio only vario. It is designed for pilots who want to enjoy free flight with the minimum of technology, and also as a reliable back-up instrument for cross country and competition flying. The Brauniger IQ Soniic is also ideal as back-up Vario for cross-country Route and Competition pilots, excellent e.g. for coastal soaring, space saving for para-glider tandem pilots and mountaineers. It's precisely the right instrument for anyone who wants to enjoy activity with the strict minimum of technology. It offers simple and reliable climb and sink acoustics individually customizable. It is also great for coastal soaring, where an altitude indication is of little importance. Acoustic Scale Indication Although the IQ Sonic has no optical indication of climb rate, the critical point between 1 m/s and 1,5 m/s (200 ft/min and 300 ft/min) is indicated acoustically. Often it is not worth circling in a thermal at less than this climb rate (unless the conditions are really weak). This is why the timbre of the climb tone changes ( this is the Acoustic Scale Indication) when a climb of 1,3 m/s (260 ft/min) is exceeded. This is in addition to the normal acoustic information which indicates your climb rate in the thermal and helps to make the correct decisions Powered by a standard Lithium Battery The IQ Sonicis powered by a standard lithium battery of the kind used in cameras. The battery capacity is approx. 200 hours of flying. A big advantage of lithium batteries is that they loose almost none of their performance in very cold conditions. Mounting The IQ Sonic is mounted with Velcro. Stick the loop side of the Velcro wherever you want your vario to be, e.g. to your helmet. Special holes in the board and case allow the sound to be reflected to all sides. Choose a place on your helmet close to your ear so you can hear the sound of the vario easily. Because of the small dimensions and the low weight of the IQ Sonic it is possible to mount the vario in many other positions, e.g. to your flying suit, or the shoulder straps of your harness, for instance Experiment to find the optimal mounting position! Switch Positions The IQ Sonic is switched on with the main switch. This switch also turns on or off the sink tone of your vario. * Switch pos: - I- Instrument ON, sink tone OFF * Switch pos: - 0 - Instrument OFF * Switch pos: - II - Instrument ON, sink tone ON Adjustment of Volume You can adjust the volume of the IQ Sonic to adapt the sound to suit individual perception and positioning. To adjust the volume the case of the IQ Sonic must be opened. The volume can then be adjusted with a small screwdriver by carefully turning the potentiometer. The potentiometer is located on the board and designated Vol. BRAUNIGER IQ-SONIC MINI AUDIO VARIO FEATURES; * Bräuniger technology and quality * Acoustic Scale Indication ( ASI ) * Adjustable Sink Tone start * Adjustable Volume * More than 200 hrs. battery-capacity * Eco-friendly Lithium battery * Dimensions: approx. 89 x 37 x 19 mm * Weight 40g
