The SM380V replaces the SMAN300 series and keeps the simple three-valve layout technicians expect while adding a built-in micron gauge and wireless range up to 350 ft, which is the single biggest reason to buy: it combines accurate vacuum measurement with robust wireless convenience in one handheld unit.
