Group guidance systems

For group guidance, soundgarden works with Okayo from Taiwan. Okayo products are TÜV-certified and approved for use within the EU. Their outstanding reliability and robust build quality set them apart from the crowd. In addition to permanently mountable charging stations, the guides also come with a special case which can be used for travel applications and excursions. You can rent or buy group guidance systems from us.
