3rd the H9 DVT. Seems to be very accurate. I've used it on a few gassers and my OS FL-70 and it seems to give good results.
It is accurate. I've notice that when the battery inthe DVT gets low, the voltage indicator for your packs can be slightly off, but that is only when the DVT's battery is low. Other than that it is a great item and I've used mine for years so far.
