We offer 2 half-day training courses on the use of ShellCalc© and more generally the production of Risk Assessments for professional firework displays. We also have a new Facebook Page for current information. Please click here for more information
ShellCalc© Pro is constantly in development and we try and incorporate as many user-generated features as possible. ShellCalc© Standard will have minor bug-solving changes as required but will not be developed further. Please ensure you have the latest version.
