History and use
This hood is made of 17 ounce hand rolled copper, cylindrical in shape, domed top, with a rolled edge at the bottom to conform with, and fit comfortably over the diver's shoulders, upper chest and back. A lifting (ducking) handle is riveted to the top of the hood and the front is fitted with a heavy bronze frame in which two (2) plate glass windows (light) are located. The windows are made watertight by being set in soft wicking with white lead.

There is an air inlet valve on the right side of the hood and internally there is a copper baffle plate deflecting air towards the viewing window (light), preventing fogging. Small holes pierced in the bottom of the hood permitted the escape of excess air in addition to that which escaped under the helmet (at the shoulders). Broad copper straps are riveted horizontally to the front and back plates on which four (4) 8.25 pound lead weights were hung.

Miller & Dunn Ocean & Salvage Co. Miami, FL. was founded in 1914 with a focus on shallow water diving helmets (hoods) and simple equipmenment. Divinhood No. 1 was simplicity in its fundaemental sense and was given the slogan 'Divinhoods - so simple anyone can use it'. Most commonly used with hand lever pumps in water less than ten (10) metres deep.

By 1927 the company had introduced its second style of hood, the Divinhood No. 2, which became the US Navy's official shallow water diving apparatus and was included as part of the ship's gear on many naval vessels.

Dinvinhoods were also popular amongst yachties and underwater naturalists.
