COMPARATIVE EFFICIENCY OF THE AQUEON AND SWIM FINS

Navy trials some 30 - 35 years ago gave the following results: 

A swimmer pair, connected by a line, made underwater swims with SCUBA using twin 90 cubic foot tanks and a compass. The distance was a measured 1500 yards.
Time, using fins only, 44 min - 30 sec. The swimmers were exhausted.
Time, using Aqueons, 24 min - 00 sec. The swimmers were fresh and strong afterwards.
Note: The second test was made only two hours after the first test by the same swimmers. They felt that they could better their time since they were new to the Aqueon.

Analysis:  The ratio of the speeds is the inverse of the elapsed times, thus:

V_aq. /  V_fins = 44 min 30 sec  /  24min

Thrust = drag for steady motion and
Thrust = K₁V² for bluff objects, etc.. 
Propulsive power = V x Thrust = K₂V³ 
Therefore the propulsive power ratio is:

Power (Aqueon) / Power ( fins)  =  (44.5/24)³  =  6.37

This amazing result is corroborated by air consumption tests within reasonable precision of 5.0.
These later tests were made by the writer and are enclosed.
