    I have this unit, it's a piece of ****. compared to the analog, this jb is very inconsistent.

    I have compared the supernova with my thermal and they are almost identical in performance, the biggest disparity is the way they react to a loss of vacuum, the thermal is way faster than the supernova, I got used to it and it does no bother me at all.

    Attempted to use my HB supernova this morning. The vac pump had been running over night, the supernova said I was at 2500 microns, I was 100% sure there were no leaks. Thought it might have been my pump, so I connected the supernova to just the pump, still only dropped to 2100. Got the trusty but bulky thermal vac guage out. Connected it to system.... 400 microns. This only the 4-5 time I tried to use the supernova. It might have worked properly the first time or two.
