Check this vintage ad out...

My guess is late '50s.

@David Wilson can probably pin it down within a year or two by the masks and fins.

I would estimate it to be late 1950s or early 1960s, (probably the latter) if the Mares Riva compensator mask in the ad is anything to go by. Hard to pin down further. Mares used numbers rather than names for their masks in their 1959 catalogue.

Makes sense. Sea Hunt originally ran from 1958-1961

I did some remediation work for the petrochemical industry years ago; and it was not remotely like this ad:

"Here, Mobil scientists, the first company team of research geologists, trained as skin divers, probe the bottom of the Gulf of Mexico . . ."

Yeah, sure . . . the St. Malo Oil Field, for example, is located at a depth of 640m (2,100ft); and The Jack Field, at a depth of 2133 (7,000ft) . . .

...who said the SI Swimsuit issue began in 1964? A Look Back at Every ‘S.I. Swimsuit’ Cover Since 1964!

Zale puts them all to shame. (Except maybe Elle Macpherson on the 1988 cover)

She taught Mike Nelson how to dive.

She taught Mike Nelson how to dive.

Better, she taught Lloyd Bridges. And more.

http://en.m.wikipedia.org/wiki/Zale_Parry

"In 1953 she became a tester of underwater equipment for Scientific Underwater Research Enterprises. Later, she and her partner, (Parry Bivens, an aeronautical and aquatic engineer) designed, built, and marketed the first civilian hyperbaric chamber for divers. They were evangelists for the purchase of hyperbaric chambers around the world to provide lifesaving facilities for divers suffering from "the bends".

In 1954, Parry set a women's depth record to 209 feet. She is said to have stopped at 209 feet when she reached the bottom. That year, she became the third female instructor to graduate from the L.A. County UICC program...

Parry's beauty and her knowledge of the sea and diving made her a natural to join the Sea Hunt show. She was cast without a single screen test. Her role in the series was primarily as a female underwater stunt double, but she did appear as an actress in a few episodes. She also assisted in teaching Mr. Bridges how to use scuba gear prior to the series going into production."

She was just the 3rd woman to achieve instructor status in the LA county system

She taught Mike Nelson how to dive.

I spoke with Zale a few years ago to see what it would take to get her to appear at one of the Sea Hunt Forever Shows in Silver Springs, FL.
She was very gracious and we had some common dive friends but her $ rate to appear was way out of our league. We finally obtained the stunt lady (Betty Frazee) who was "The Girl in the Trunk" in that episode of Sea Hunt. (Magician trick goes wrong and Mike has to save the girl trapped in the trunk underwater).
