The first CO 2 powered gun was designed by the late LA Co & NAUI instructor Bill Barada in 1935.
It was produced commercially by Mel Fisher, LA Co UW instructor when he owned Mel's Aqua Shop in Redondo Beach California The same CO2 powered gun was produced commercially by a Florida based company called Lo Bo in 1954.
In the 1950s while in the USAF during Korea I and several others made CO 2 powered guns. About 30 years ago I authored an article about the guns and our diving adventures in the now defunct American Magazine
Discover Diving in my dedicated column "The way it was" tilted
"The Magnificent Gas Gun"
In the mid 1950s three Co2 cartridge powered spear guns were produced in the US :
1) The
Barracuda by the late Chuck Blakeslee, who at the time was the co founder of Skin Diver Magazine. It was manufactured some where in Los Angeles, possibly Compton
2) The
Mark IV manufacture in Huntington Beach California
3) The
Viking manufactured in the mid west of the US
All three had a short life span - the Co2s were unreliable,. they cost 5 cents per shot, (from war surplus stores) the made noise and the spent cartridges were like a dead pelican-- So what do you do with a dead pelican?
It was about late 1950s or early 1960s they were declared illegal to use in all local & international spearfishing competitions and the Co2 Powered Spear guns slowly disappeared from the market place and common usage.
It is a dead horse...No need to kick it
