Probably not the BEST advertisement for the units.
At the risk of sounding contrary, maybe this is a good way to begin to separate the
underwater tourists from
divers. The UWTs get a chance to go underwater, check the box on the list, and move on to the next piece of candy in their Whitman Sampler box of 'been there, done that, got the t-shirt' experiences. The potential DIVERS get even more excited by what they see underwater, and actually do decide to pursue dive training, or at least schedule a DSD for the next port stop. This seems more benign than jet skis.
And, if they are restricted by the floats, they (presumably) aren't crashing into the reef.
