Our launcher dummies are made tough. The exterior is a heavy duty lined canvas cotton in two part "Flash" effect for greater aid in marking . The inner tube is stainless steel so can work on land or water without the corrosion issues steel or alloy gives. We use a specially selected adhesive and construction technique that holds the dummy together for longer given the violent launch and landings these often receive. Its consistently sized and we believe fits most launchers available in the UK . Made in the UK. Comes complete with a new seal for your dummy launcher .
