This is a fascinating diving helmet made by the General Aquadyne company during the 1970s. It is a model DMC-7 TV helmet, which is based on the then-popular DMC-7 helmet but with a light and camera attached to the top of the helmet.


Unlike helmets that simply bolted on a light and television camera, General Aquadyne incorporated both features into the DMC-7 fiberglass helmet. The result was state-of-the-art in the 1970s and likely quite an expensive helmet. Today, very few of these still exist in any condition.


This example is in beautiful condition, with the original black-painted body looking nearly like day one! All of the metal components are also in excellent condition, still showing a shine. Based on its condition, it would be a safe bet to assume this helmet was never put in the water and possibly used as a display model. There is no neck dam. The helmet weighs approximately 28 pounds.


Based on its rarity and superb condition, this helmet will undoubtedly increase in value significantly over the years!


All diving helmets in this auction will be accompanied by a certificate of authenticity from Nations Attic.
