Paired my Tickr X with my watch. It appeared twice. One is listed as a number (ex 522689) the other is listed as TickrX 599. I figure one of these is Ant+ (guessing 522689) and the other is Bluetooth (TickrX 599). Is this a correct assumption? Is there a way to ID which one is Ant and which one is BT? Lastly, are both Ant and BT equally reliable/accurate?
