Neutral gas puffs are injected in the SOL region to visualize the plasma turbulence increasing the contrast and light emission. We report here on the design and implementation of such a diagnostic for COMPASS. The design of a low divergence nozzle will be presented as it is of importance to obtain local measurements of the turbulence. The first tests of the optical and injection systems will also be shown.
