supraGuide refurbished
The sustainable and affordable way to transfer knowledge
tonwelt is committed to sustainability. It goes without saying that our devices are designed to withstand the daily bumps and bangs of museum life for an extremely long time. Whether it’s a stuck button, a fading battery or a faulty display, almost all of the components in our devices are designed to be easily replaced. That’s how we avoid unnecessary electrical waste while at the same time helping to reduce energy use, costs and inconvenience.
The idea behind refurbished devices is familiar to us all: Second-hand devices with a short history of use are professionally cleaned, reconditioned, repaired and fully tested for functionality. At tonwelt, we check every aspect of our refurbished equipment thoroughly in order to ensure that your audio tours can continue to run smoothly. We also offer an 18-month warranty on all our refurbished devices. But that’s not all. To make sure it’s not just our refurbished equipment that impresses you, we’re now offering a 25% discount on the audio production of any additional extensions that you make to your tours in connection with our refurbished devices.

A part is a part even when it’s apart
Because we manufacture our supraGuides ourselves using transparent supply chains, we’re able to carry out our own repairs. Our service teams know every screw, joint and headphone socket of our devices inside out. We’re therefore in a position to replace almost any component. The short distances to our service-centres also mean we’re able to return your repaired devices quickly.The idea behind refurbished devices is well established: Used electronic devices are taken back by an authorised dealer after a short period of use, where they’re then professionally cleaned and checked for functionality. But tonwelt supraGuide refurbished goes one step further: Once the supraGuides have been returned to us, we professionally clean and disinfect them. All components that are subject to mechanical wear and tear are checked thoroughly and replaced when necessary. Displays and batteries are tested for damage and efficiency, and all devices undergo a complete functionality test, the results of which are presented to the customer upon delivery. As a result, our supraGuide refurbished devices remain ideally suited for daily use in your museum. That’s why we give you an 18-month warranty.

Expand your audio tour with multimedia and multiple languages
Audio content is still the best medium for the transfer of knowledge. But sometimes audio content needs visual support through elements like photos, videos or an overview map. Our central supraCMS system makes it easy for you to expand your existing audio guide. But why not go one step further, by turning your new multimedia guide into an interactive tool for your entire tour? If you already have a tonwelt visitor guidance system and you decide to add supraGuide MULTI or supraGuide TOUCH as part of your supraGuide refurbished multimedia upgrade, we’ll also give you a 25% discount on the audio production when you expand your tour to include an additional language. That way, you’ll make it possible for even more of your international visitors to enjoy top quality multilingual knowledge transfer. What better way is there to transfer knowledge both sustainably and affordably? Take a look at our various international projects here, and discover for yourself just how many possibilities there are to use multimedia within your guided tours.
