What other water sports do you do besides foiling? What is particularly important to you when it comes to equipment and what do you think about e-foiling? Manufacturer Duotone is looking for answers to these and other questions in a survey that has now been launched. The aim is to optimise its own product range and website. Taking part could be worthwhile, as Duotone is giving away a brand new Unit Wing to all participants (HERE is a test report)which you can ride with either handles or boom.
