Because DZ-series parts differ by their numeric member, the 54.94 marking is carried through EEPROM, label, and listing so it cannot be confused with an adjacent unit in the series. DDM/DOM support gives the host continuous visibility into the optic while it runs. MSA conformance testing, identity checks, and cleanliness inspection precede shipment for every serial number. Ownership includes the GreenLights4Life® Limited Lifetime Replacement Warranty. In-stock items ship same or next business day — contact 10.4@tenfouroptics.com to confirm availability and lead time.
