SCUBA LAB FIN REVIEW

SCUBALAB REVIEW

Fin Manufactures make all kinds of claims about the underwater swimming efficiency of their fins, usually based on little or no data.
But there are clear differences in fin efficiency that can be documented by conducting hundreds of controlled, head-to-head evaluations.
So far Scuba Lab has performed over 3,000 such test. Here's what the data says:

• The propeller fins tested for this article performed, on average, 27 percent more efficiently than the best paddle fin.
• The performance of the best propeller fin we've ever tested is 142 percent more efficient than the worst paddle fin.
• The performance of the best paddle fin we've ever tested is 64 percent more efficient than the worst paddle fin.

So, yes, some fins are clearly better than others; one fin technology produces better efficiency than the other.
But it takes more than marketing claims to sort out the differences. It takes rigorous testing and hard data.
And you're holding in your hands the only place where you can find it.

BREATHING RATES IN PSI PER MINUTE

FIN EFFICIENCY: BY THE NUMBERS

From the hundreds of course runs, the 10 best runs for each fin were used to evaluate efficiency and overall performance.
This graph reports three numbers for each fin:

• The left end of each bar represents the best air consumption (in psi/minute) that any tester had for that fin;
• The right end of each bar represents the worst air consumption any tester had for that fin;
• The bold number on each bar is the average for the 10 best test runs.
• This psi per minute data came from full course runs at 15 feet with 75.8-cubic-foot steel tanks.
