First of all, I know that there seems to be a preference for Luxfer due to its buoyancy characteristics. I've read all over the net that Catalinas are simply heavy even when empty. Here are the specs as per their respective websites.
Luxfer S40 -0.7 lbs +2.3 lbs
Luxfer S80 -1.4 lbs +4.4 lbs
Catalina S40 -1.5 lbs +1.4 lbs
Catalina S80 -1.6 lbs +4.1 lbs
Personally, I don't find the differences to be too much. Need an opinion
on what I should consider getting for myself. I've read in many places that only Luxfer should be used. But given these specs, I don't really see that much justification for the Luxer only idea.
I'd just like to get an opinion on the specifications here. Thanks a million guys.http://www.luxfercylinders.com/products/scuba/specifications/us_imp...http://www.catalinacylinders.com/scuba.html
