Can the Marlin be used in official competition?

While current rules may not have specific rules for audio equipment for swimming, we believe it is just a matter of time before all competitions will ban it because of the competitive advantage it offers. We envision there may be competitions that allow it provided all participants have equal access to Marlin. As a training tool, Marlin can help you improve your sighting. When you wear it during practise, you will learn to get a better feel of your direction because of the instant feedback it provides. You will also get a better idea of your optimal performance when you can swim in a straight line. In official competition , even though you may not be able to use the navigation feature, you can still detach the headset and use it to track your path for review after the competition.
