Sure, the Satellite Quick Marker is just set of slap bracelets that survived the late 80's. But these slap bracelets have the most noble use of the all slap bracelets that have come before them. Differentiating friend from foe! 2 red and 2 yellow team bands make little work of setting up teams for that backyard skirmish. Additionally the Quick Marker can be used to break your team up in to easily identifiable squads.
