This is a KILLER module if its the original with the Shiver switch. I sold mine off (needed cash) and really miss it. Of all the Salvos I've tried, it was one of the top two (along with the Masholdano) Wish I had the funds! And you've got another beauty sitting there too- The snorkeler!! Mine was "lost" (ok it was stolen) in the mail. Very underrated module too.
