Gecko is an adjustable water spray gun for the urban gardener, result from an exploration of form and ergonomic studies using various modelling processes. A user trial was conducted with a foam model and questionnaire, the results of which were combined with anthropometric data to provide input for refining the design. The handle is designed to suit a variety of users, from the smallest hands to the largest, left handed or right. Users can select from eight different spray styles to suit all situations using a thumb dial. A smooth body makes for easy cleaning and a large pulse button allows for easy water control with your fore finger.
