The Tetrax system uses four strong neodymium magnets--arranged to reduce magnetic interference--to hold your favorite portable devices to your car's dash or air vent. An unobtrusive disk magnet attaches permanently to the back of your phone, GPS or MP3 player. The Tetrax GEO holder affixes to an air vent using a clamp system and can hold up to 1.6 lbs. (750g) while withstanding up to 5Gs of acceleration. Includes two adhesive-backed mounts.Price:
