In order to train officers how to correctly use P.A.V.A., we offer a very user friendly training system which involves inert cans. These cans are filled with de-ionised water and behave and feel exactly like that of a P.A.V.A. can. The system is called the “Clip-Cap” system as the caps on the cans are reusable. This means the user only needs to replace the actual can unit, ensuring costs are kept to a minimum.
