October 1969 issue of Skin Diver for this weeks TBT. I saw a full page ad for a company called OEC (Ocean Equipment Corp), What originally caught my eye was the underwater telescope, That's neat I thought, except it wouldn't be useful in our emerald green water.

Then I saw the Closed Circuit breathing system. And the price. $2975!!! Remember this is 1969! But what entertained me the most from the ad was at the very top. An Anesthetic kit for fish collecting. I immediately had visions of getting some and applying to some dogfish during a dive so they'd sit still long enough so I could take a picture of more than it's tail fin as it scoots away. Then I started reading more about it (I love Google) and see that they still use Anesthetic in marine biology for sample collections in tide pools. Very cool.
