Have you ever seen the old Scubapro helium-filled 500-feet depth gauges? If you show up with one of those and a MK-VII you will give every other diver on the boat a permanent inferiority complex.
Ummm....I actually own one of those. I actually bought it last spring as new old stock from a dive shop that closed it doors. It works great with my double hose regs and horse collar BC. I often wonder what possessed Scubapro to market a gauge good to 500'. I suspect they were really optimistic about dive technology.
