Science Experiment

[mommy43]

I am finishing up a science experiment involving the loss of the red light rays at different depths under water. I am in the process of writing by report. Can anyone tell me when recreational divers started using depth gauges? I would also like to know if anyone knows when Captain Ron Stewart went to Bonaire? Any help would be appreciated.

Use of depth gauges began about the same time as water proof watches, when men first made dives using SAS or SCUBA. I know they were in use in the early 1950's. These instruments were in demand by SCUBA divers in particular because there was usually no surface support.

According the museum in Bonaire Captain Don arrived in 1962.

As the story goes, he used a red ribbon that he tied to his mask strap to tell depth rather than an actual depth gauge at the time, but depth gauges were available.

Do you mean Capt Don Stewart? If so I don't know the year but he is a member of the Bonaire board and I suspect he would be happy to answer the questions himself. You could PM him there. Bonaire Talk - The place to discuss everything and anything about Bonaire!

Arrived May 21st, 1962. As told by the man himself in a post here on Scubaboard: http://www.scubaboard.com/forums/abc-islands/255611-island-adrift-post-3-part-1-2-a.html

I had forgotten he had joined this board as well, maybe he will chime in, hope so.

The Italians had depth gauges in the Decema Mas operations during WW 11.

Crude capillary guages were produced and sold by US Divers in 1950...I have one.
