After the US Navy decided to replace the iconic Mark V helmet, they choose to use the Morse Diving Equipment Mark 12 fiberglass helmet. This model was in use mostly during the 1980s before being replaced by lighter weight models. Today this helmet has been rapidly gaining in popularity in the collector market.

A vast majority of Mark 12 helmets that have survived have been decommissioned by the Navy before they sold them as surplus. The decommissioning process involved pushing the base of the helmet together, causing irreparable damage and use impossible. A precious few of these helmets escaped destruction, making them prized collectibles today.

This example is one of the lucky helmets that did not get destroyed! Made in February of 1982 at the Morse Diving Equipment facility in Boston, MA, this helmet is serial #0399. The helmet is in excellent condition with only minor paint scratches from light use. The inside of the helmet is also in excellent condition with no deterioration to the components. The neck ring detaches with ease and there are no missing parts.

Finding a Mark 12 in this condition is extremely rare, so do not pass up on this opportunity to own an icon of US Navy diving history!
