Apparently this device from IOLITE is USAT race-legal

GPS-thingy on your head that is wired to direction-indicating lights in your custom goggles.
That would certainly save me heaps of time in open water.
It seems wrong; but I stress – apparently USAT race-legal.
Who needs SwimSmooth when you can Swim Straight with this?
I seem to vaguely remember seeing a patent that Garmin had for this sort of thing.
In the words of the song “There may be trouble ahead” on many fronts, especially if I can keep with the leading swim pack (OK the one behind the one behind them)
