Re 130 feet maximum depth
I searched 'Underwater Recreation Manual , July 1954 by Bev Morgan the very first LA County diving instruction manual, which the first organizational dive manuals published a very historical document .
There is no reference to maximum depth
I searched the second LA County diving instruction manual, Underwater Recreation by Al Tillman No date on publication but I suspect 1958=9 (Al passed away about 10 years ago- no way to verify date)
Also there is no reference to maximum depth.
I have all of the LA co recreation al diving manuals as well as a number of long forgotten dive manuals in my library and will review in the future-- just to see if 130 foot is mentioned
I recall from the day I transitioned from free diving to SCUBA , in 1951, at that time 130 feet was considered the maximum depth or sport divers
Perhaps 130 feet is a modem urban legend of SCUBA ??
